This is a submission for the June Solstice Game Jam I've been in online queer communities for a long time, and one thing that's always stood out is the endearing obsession with pop culture. The artists, the music, the fashion, the references. Every form of art gets appreciated, deeply analyzed, and celebrated. Diva Academy is an attempt to reflect that energy and honor Pride month and the pop culture that comes with it. What I Built Diva Academy is a pop culture trivia adventure. You play as a fresh face entering a campus where the currency is knowledge. The questions cover everything from ballroom culture and drag history to Beyoncé's discography and the origins of the Pride flag. The game runs in sessions: NPCs challenge you to timed trivia battles. Reach your REP(utation) goal to win, or hit zero and you're out. Earned REP converts to permanent currency between sessions, making it a rogue-lite-lite-lite experience where you gradually get stronger even when you lose. The game is built with vanilla HTML5 Canvas, CSS, and JavaScript. It features: 6 explorable rooms 4 NPC tiers - Starlet , Diva , DJ , and Mother - each with distinct personalities and increasing difficulty A rival system where a recurring NPC named Vex Vivienne spawns across the map and hunts you down A permanent perk system where REP earned in each run converts to permanent currency for buying perks like Grace (forgive one wrong answer), Clutch (survive at 0 REP once), and Haste (extra time on the timer) A Spotlight mechanic - defeat a Diva-tier or higher NPC and you earn a one-time 1.5x REP buff for your next face-off Two minigames - Hangman (guess the pop star name) and Pop Connect (link two artists through a mathematically perfect, AI-grounded collaboration graph with look-ahead validation) The Turing Challenge - Archivist Alan tests your ability to distinguish real pop culture quotes from AI-generated fabrications A customization system that unlocks new dress and hair colors as you defeat NPCs An

This is a submission for the June Solstice Game Jam Archive — The Last Historian of Humanity What if history wasn't discovered... but selected? History is often treated as something permanent—something waiting to be uncovered. Archive asks a different question: What happens when humanity loses the ability to tell the difference between truth, memory, and fabrication? You play as the final Archivist after the collapse of civilization. Humanity's knowledge survives, but it has become fragmented, contradictory, and corrupted. Your responsibility is no longer to preserve everything—you must decide what deserves to be remembered. Every decision changes the civilization that will inherit your version of history. What I Built Archive is a narrative investigation game where players reconstruct humanity's past by examining historical memories, investigating evidence, resolving contradictions, and deciding what becomes official history. Unlike traditional mystery games, there is rarely a perfect answer. Instead, every investigation asks questions such as: Should conflicting memories be preserved? Is stability more important than truth? Can compassion justify rewriting history? If no one can verify the past, what does "truth" even mean? Each recovered memory is presented as a historical article. Players investigate through classified documents, research papers, witness testimonies, forensic reports, personal journals, and government archives before making irreversible decisions. Those decisions reshape the civilization that follows. By the end of the game, players don't simply receive a score—they discover the kind of society they created. Why It Fits the Theme The June Solstice represents a turning point. It is the moment when one season gives way to another, when light begins yielding to darkness, or darkness begins yielding to light. Archive explores a similar transition. Not between seasons... but between certainty and uncertainty. Human civilization reaches a moment where

This is a submission for the June Solstice Game Jam Link to Game Home Page - here Link to Game Docs - here What I Built Heliograph is a short 2D solar-noir platformer. You are a courier who wakes with no memory on the summer solstice , the longest day of the year — the one day the sun is supposed to never quite die. A cracked handheld computer flickers on in your hand and tells you the truth: tonight the sun will set, and a relay station full of light has one unfinished message left to send before the dark. Sunlight is your battery and your map — it refills your light cell and reveals the route. Shadow hides you from the station's machines, but it slowly drains you, so you can never simply wait. Every screen is a negotiation between expose, charge, traverse, hide, decode. The core puzzle is a light relay . Most of the station is dark. Standing in a live sunbeam, you trip a relay that throws the light forward — a beam snaps to the next aperture, that beam comes alive, its cipher glyph becomes readable, and the chain continues until the final relay powers the exit terminal. You are literally carrying the light deeper into the ruin one beam at a time. Skip a relay and the road ahead stays dark and unsolvable. The jam theme is the solstice — light and darkness, and the passage of time. Heliograph is built entirely out of that tension: Light vs. darkness is the core mechanic, not a backdrop. Light is power, information, and danger at once; shadow is safety that costs you. The passage of time is the antagonist. The whole game is one long solstice day bleeding into night, and the message has to leave the station before dark. The station is a heliograph — a real Victorian device that sent Morse code by flashing sunlight off mirrors. Light is the message. There are no cutscene dumps. ACE, your handheld guide, narrates the opening, and after you decode each level's keyword — SUN → ARC → LUX → RAY — ACE decrypts one more fragment of the truth: why you're here, that you may not

This is a submission for the June Solstice Game Jam What I Built The Imitation Game The Imitation Game is a real-time multiplayer social deduction game inspired by Alan Turing's famous Imitation Game the thought experiment that eventually became known as the Turing Test. Most people believe they can easily tell the difference between an AI and a human. They assume AI is too perfect, too logical, too fast, or too obvious. The Imitation Game challenges that assumption. Players enter a live chat room convinced they'll spot the machine within minutes. Then conversations begin, suspicions form, accusations fly, and certainty starts to disappear. Was that awkward response written by a human, or an AI trying to sound human? Was that emotional story genuine, or generated? Was the player who stayed silent suspicious, or simply distracted? By the end of a match, players often discover that identifying an AI is far harder than they expected. The real question isn't whether the machine can fool people. It's whether people are as good at detecting machines as they think they are. Instead of a single human interrogating a machine, players are placed into a live chat room with other participants and asked a simple question: Can you identify which player is actually an AI? Hidden among the players is a Quanbit , a rogue artificial intelligence from the year 3026 . Its mission is simple: blend in, appear human, avoid suspicion, and survive. The challenge for human players is equally simple, but far more difficult in practice. They must carefully analyze conversations, voting patterns, response timing, and social behavior to determine who among them is secretly the machine. The game currently features two distinct modes, each designed around a different style of deception. Eyefold Eyefold is the purest form of the game's Turing Test experience. Players enter a room where one participant is secretly a Quanbit. Conversations unfold naturally, and everyone is free to discuss any topic.

This is a submission for the June Solstice Game Jam TL;DR Save the Sun is a kids' deduction game set on the eve of the June solstice: you race Sköll—the wolf who wants to eat the sun—to Sól's one true rune before he catches her and the longest day never dawns. Gemini does two jobs and the engine referees both: it reads the player's questions—typed, or spoken aloud and transcribed—as the Oracle, and it plays the wolf as Sköll. The engine owns the secret and never hands it to Gemini. Everything here is checkable: play a round · watch the demo · anchildress1/save-the-sun . What I Built Blame a board game 📞 The idea started with Dream Phone , a 90s deduction game I played as a kid—you dial pretend phone numbers and narrow down which boy has a secret crush on you. The catch: it needed 2-4 players and fell flat with two. So I rebuilt it as a two-player game à la Guess Who and gave the second seat to Sköll, an AI opponent to race. That became Save the Sun , a deduction race for players aged 8 to 12 against Sköll, the Norse wolf who wants to eat the sun. The story of Sól and Sköll comes straight out of Norse mythology and is one of my all-time favorites. Sól drives the sun-chariot across the sky, and Sköll chases her—every day, all day, forever—until Ragnarök, when he finally catches her and the sun goes out. The game drops you into the night before the solstice with the wolf a stride behind: get the true offering to Sól before he reaches her, or the dawn never comes. Teaching AI to lose 🧩 The hard part of a kids' deduction game is making the AI beatable without handing it the answer. The opponent never sees the secret: a deterministic engine holds it and referees every move, and Gemini only ever plays on top. Sköll's side was easy—he answers in structured JSON—but a loose human question has to be read into something the engine can resolve first, and that reading is the only job I gave the Oracle. Twenty-four runes, one short night 🌙 The round itself is small on purpose. Th

This is a submission for the June Solstice Game Jam ( https://dev.to/challenges/june-game-jam-2026-06-03 ) What I Built I built Solstice Assassin, a tactical stealth-action game set inside a collapsing digital mainframe. You play as Alex, a self-aware digital anomaly trapped inside the Solstice Grid, a secure virtual system originally created by Alan Turing. Alex awakens with almost no memory except one critical piece of information: «CREATOR: ALAN TURING» The catch? Today is the Summer Solstice, the longest day of the year, and at midnight the system will execute a complete purge of all dynamic data. Alex has one final day to recover lost memories, outsmart the system's security forces, and find a way to survive. Gameplay combines tactical movement, stealth, procedural level generation, enemy AI, and resource management. Players infiltrate security sectors, collect awareness data, avoid or eliminate hostile "Cleaners", and manage powerful abilities such as Dash, Cloak, Radar, and Time Warp. The Solstice theme isn't just part of the story—it directly affects gameplay. Throughout each mission, the system progresses through different Solar Phases: 🌅 Golden Dawn ☀️ High Noon 🌇 Crimson Sunset 🌑 Eclipse Each phase changes visibility, stealth effectiveness, enemy behavior, and the overall tactical landscape. High Noon makes players highly exposed, while Crimson Sunset rewards stealth and careful planning. By the time Eclipse arrives, the entire system begins breaking down. My goal was to create a game where the passing of the longest day isn't just a background theme but something the player constantly feels through the mechanics themselves. Video Demo https://youtu.be/48RM1iTZjOg?si=JYz86wVzNMjeZmmw In the video I demonstrate: Tactical movement and infiltration Dynamic Solar Phase transitions Enemy AI behavior and pathfinding Awareness recovery and progression systems Alex's abilities AI-generated mission briefings and voice interactions Procedural level generation End-o

This is a submission for the June Solstice Game Jam . What I Built Bletchley's Longest Day is a browser-based cipher escape game set inside a fictional Bletchley Park night shift. The player has to stop a U-boat convoy attack before dawn by clearing five rooms. Each room contains three escalating locks, so the full escape requires 15 solved puzzles . The game combines Caesar shifts, A1Z26 number decoding, Morse, anagrams, fragment ordering, a visible countdown timer, mistake penalties, hint penalties, account-based score saving, and a best-score leaderboard. The solstice theme became the core dramatic clock: night is running out, first light is coming, and the player has to decode the final signal before dawn. Video Demo The demo shows the opening briefing, the three-lock room flow, the Gemini hint penalty, and the final victory state that only appears after all 15 locks are cleared. Live game: https://bletchleys-longest-day.onrender.com Code Repository: https://github.com/himanshu748/bletchleys-longest-day How I Built It The game is a lightweight Node-served browser app. The front end is a hand-built HTML/CSS/JavaScript game surface, while server.js serves static files and protects the Gemini API key behind a server-side /api/hint endpoint. The main design goal was to make the game feel like a tense intelligence desk rather than a generic puzzle page. Every room has atmosphere, evidence props, lock-specific copy, feedback states, and a timer that is always part of the pressure. The puzzle structure was tuned around three ideas: Three locks per room : each room has to be solved in stages, so the player earns the escape instead of clicking through one answer. Time as score pressure : wrong answers and hints cost time, while clean solving preserves the best leaderboard run. Guest mode vs signed-in mode : guests can play the full game, but Gemini-powered hints and saved leaderboard scores belong to authenticated players. Google Gemini is used as a server-side hint offi

This is a submission for the June Solstice Game Jam What I Built I built a simple cipher game with 6 levels to decrypt the cipher text based on frequency of words and hints to obtain the plaintext version. Video Demo Code samarthsubramanya / JuneSolstice_GameJam_2026 ☀ Solstice Cipher A code-breaking puzzle game built for the June Solstice Game Jam — and a small ode to Alan Turing . Six encrypted messages stand between you and the longest day of the year. Each one is a substitution cipher hiding a message about a June celebration — International Sushi Day, the World Cup, Pride, Juneteenth, Turing himself, and the solstice. Crack each cipher using frequency analysis (the same statistical reasoning Turing's team used at Bletchley Park) and the sun climbs a little higher with every solve. Break all six and you bring the light all the way back. Theme The June solstice is a global moment of transition — the longest day in the north, the shortest in the south. The game makes that literal: decoding is the act of bringing back the light.

This is a submission for the June Solstice Game Jam It's interesting how the most exciting ideas always arrive when I have basically no time to work on them. A few weeks earlier, I had finished my submission for the GitHub challenge by bringing an old WinForms game back to life. That project turned out to be a lot of fun. Then Sylwia Laskowska published a great article about Google's WebMCP . The idea fascinated me, but I wasn't sure where I could actually use it. Then the June Solstice Game Jam was announced. The idea hit me like a lightning bolt: What if I made a game that both humans and AI could play? Let's do it. What I Built I created a puzzle game with a solstice theme called Tower Before Dusk . The goal is simple: reach your home tower before sundown. Every action costs time. Every step brings sunset a little closer. Rivers block your path, rocks force detours and the only way across water is to collect enough wood and build bridges. Move too much, collect unnecessary resources, or choose the wrong path, and night will arrive before you make it home. The challenge isn't just solving the puzzle. It's solving it efficiently. And apparently, that's difficult for both humans and AI. Video Demo In this demo, Gemini 3.1 Flash-Lite tries to solve the level using the exposed game tools. It fails, then I restart the level and solve it manually. That failure is part of the point: the tools worked, but reasoning through the puzzle was still hard for the lightweight model. tower-before-dusk.gramli.workers.dev Code Gramli / tower-before-dusk A TypeScript puzzle game demonstrating WebMCP, where humans and AI solve the same challenges under the same rules. Tower Before Dusk Tower Before Dusk is a tile-based puzzle game about reaching the tower before sunset. Plan each route carefully: every move spends daylight, trees provide wood, and water can only be crossed by building bridges. The game is built as a modern browser app with TypeScript, HTML canvas, and Vite. It also ex

This is a submission for the June Solstice Game Jam What I Built Perfume Calendar: June is a small atmospheric adventure game inspired by nature, folklore, and the changing moods of June. Players take on the role of Mavka , a forest spirit, and travel across a calendar-shaped map representing the 30 days of the month. Each day has a different nature element—forest, sun, water, or mist—that affects the player's energy. The goal is to make strategic movement choices, gather enough energy from beneficial days, and reach June 21st , the summer solstice, with at least 10 energy points. If successful, Mavka awakens the forest and completes her journey. My intended goal was to create a simple but thematic experience where a calendar becomes an interactive game board rather than just a way to track dates. I wanted players to feel like they were moving through a living month, with each day offering different opportunities and risks. The game relates to the challenge theme by transforming a calendar into the core gameplay mechanic. Instead of simply displaying dates, the days themselves become locations that influence the player's progress. The June setting, seasonal energy, and the solstice objective reinforce the idea of time, nature, and progression through a month in a playful and interactive way. Video Demo Code wailixi / Mavka Game How I Built It I built the game using HTML, CSS, and JavaScript without any external libraries. The 30 days of June are displayed as a 6×5 grid , where each day has a terrain type (forest, sun, water, or mist) that affects the player's energy. A key design choice was turning the calendar into a navigable map. Players move Mavka between days, collect energy, and plan their route to reach June 21st with enough energy to win. Movement restrictions add a simple strategy element, while color-coded terrain helps communicate each day's effect. My goal was to create a small, atmospheric game that transforms a calendar into an interactive adventure in

This is a submission for the June Solstice Game Jam What I Built My game, Sunny Up, celebrates International Sushi Day! I intended to make a cute casual game because who doesn't like simple and cute things, right? I was inspired by games I liked in the 2010s that were simple, fun, and strangely addictive. The game's theme also has a lot to do with the solstice, which can be observed in the four scenarios where the game makes reference to it. Video Demo Code maikpalharoni1 / sunny-up my game sunny up for june solstice game jam sunny-up my game sunny up for june solstice game jam View on GitHub How I Built It Fun fact: I started brainstorming the idea while I was working on another game, a cute virtual pet (which even celebrates a traditional festival in my country in June, called Festa Junina), and in doing so I became obsessed with the stories of virtual pet developers from the 2010s. I mainly read about Paul Salameh and his game Pou, and also about Rovio with Angry Birds, which were my favorite stories. I combined two mechanics from both games, and that's where I decided how the game would work. I'm a noble pioneer of HTML, CSS, and JS, so I used AI to give me greater support, optimization, and help me write the code in parts of the project. I'm not a designer, nor can I afford one. I used Gemini AI for the game's graphics, acting as an art director to ensure everything came out as best as possible, removing the AI ​​sloppy aspect and giving the project more life. Prize Category I really liked the artwork with Gemini and the emotional support and evaluation of Google's AI mode, so I think it's worth considering for the Best Use of Google AI category, even though I'm not aiming for any specific category. Play the game Online in browser on Itch.io: https://coffee-calf.itch.io/sunny-up Thank you for reading, it was fun participating in the challenge!

This is a submission for the June Solstice Game Jam What I Built Beat the Oracle is a daily FIFA World Cup 2026 prediction game where you go head-to-head against an AI — Google's Gemini 1.5 Flash — to call match scores before kickoff. Out-predict the machine and you win the day's Turing Test. Lose, and the Oracle has outsmarted you... until tomorrow. Every day you're served the same 5 matches as everyone else: some already played (scored instantly), some upcoming (lock in your call and come back). The Oracle reads each team's recent World Cup form and makes its own prediction with written reasoning — which you only see after you've locked in yours. No peeking, no cheating. Just you versus the machine. Scoring: Result Points Exact scoreline 3 🎯 "Enigma Cracked!" Correct result (W/D/L) 1 ✅ Miss 0 ❌ Why this fits the June Solstice Game Jam This jam asked for a game inspired by the solstice or any June celebration — and Beat the Oracle is stitched to June on two threads the challenge itself calls out: The World Cup is June's global celebration. The prompt names it directly: "the electric teamwork and high stakes of the World Cup, bringing the entire planet together in the spirit of play." That's the playground this game lives in — and as a bonus, I built it from 🇨🇦 Canada, a 2026 host nation . June is Alan Turing's month. Born June 23rd, Turing is the reason this jam has a "father of computing" prize at all. So I didn't bolt a Turing reference onto a football game — I built a playable Turing Test and gave it a World Cup costume. Turing's 1950 question, "Can machines think?" , becomes a question you answer with your gut every single day: can a machine predict football better than you? And the "daily" loop — new matches each day, your score reset, the machines winning "for today" — leans into the solstice's own theme of cycles and the passage of time. Every day is a fresh test. Every match is a new cipher. 🔗 Live demo: hema-nambi.github.io/BeatTheOracle Code Hema-Nambi /
