Two browser games use Alan Turing themes and interactive solstice or puzzle mechanics

Solstice Runner — A Browser Game Tribute to Alan Turing

This is a submission for the June Solstice Game Jam What I Built Solstice Runner is a browser-based endless runner where you play as a ray of sunlight racing across the June solstice sky — the longest day of the year. Your goal: jump over creeping shadow obstacles and survive as long as possible. As you play, the world transforms around you. The sky slowly shifts from warm midsummer gold to deep solstice night — a dawn-to-dusk progression tied to your score. Stars emerge, the moon rises, and the obstacles grow faster and taller. The game ends when shadow swallows you. Alan Turing tribute: the shadow obstacles are etched with binary code — fragments of the ASCII encoding of "ALAN" and bits from the binary patterns of early computing. As you play, facts about Turing appear at the bottom of the screen, reminding you whose birthday falls just after this solstice. He was a man whose brilliant light the world tried to extinguish. In this game, you fight to keep the light alive. Video Demo Code MakendranG / solstice-runner A June Solstice browser game — tribute to Alan Turing solstice-runner A June Solstice browser game — tribute to Alan Turing View on GitHub The full game is a single HTML file — no frameworks, no build tools, just vanilla Canvas 2D. Key files: index.html — the entire game (canvas, game loop, rendering, input handling) How I Built It The game is built entirely with the HTML5 Canvas API and vanilla JavaScript — no libraries, no frameworks. Everything runs in a single <canvas> element. Game loop: A standard requestAnimationFrame loop handles both update and draw each frame, keeping physics and rendering in sync. Physics: The player has a simple gravity accumulator (vy += 0.58 per frame) with a ground clamp. Jumping applies an instant upward velocity (vy = -12.5). It's minimal but feels satisfying because the gravity is tuned to feel snappy rather than floaty. Sky progression: Instead of a timer, the sky phase is derived directly from the player's score — skyPhase = score / 280. This means the longer you survive, the deeper into night you go. Colors are linearly interpolated between hex values for dawn and dusk, so the sky transitions feel smooth without any keyframe animation system. Obstacle spawning: Spawn interval shortens as the score rises (interval = max(38, 88 - score * 0.38)), creating a natural difficulty curve. Tall obstacles (60–84px) appear once your score passes 8, requiring better-timed jumps. The Turing layer: Every shadow obstacle has a ~55% chance of displaying a binary string down its face — fragments of ASCII "ALAN", "10" (binary for 2, Turing's birthday month), and "T". These are purely decorative but reward players who notice them. Additionally, a fact about Alan Turing surfaces every ~420 frames, surfacing quietly below the game without interrupting play. Celestial bodies: The sun tracks across the sky and fades as skyPhase rises. The moon fades in after skyPhase > 0.35 and gently bobs using a sine offset, giving the night sky a living quality. Particles: Jump particles are emitted from the player's base on each jump — 8 small circles that arc outward and fade over ~22 frames. They reinforce the feel of launching a burst of light. Prize Category Best Ode to Alan Turing Alan Turing was born on June 23 — two days after the solstice this game is built around. He was one of the greatest minds of the 20th century: the father of modern computing, the codebreaker who helped end World War II, and the man who first asked whether machines could think. He was also persecuted by the British government for being gay and died at 41. This game honors him in several ways: The shadow obstacles carry binary — the shadow in this game isn't random noise; it's encoded. Binary fragments of "ALAN" and early computing symbols are etched into each shadow pillar. The thing trying to stop you isn't mindless — it has structure, like the ciphers Turing spent his life breaking. The player is light — Turing's work was about illuminating problems that seemed unsolvable. Playing as a sunbeam fighting off darkness felt like the right metaphor. Turing facts surface during play — players learn about his work and his life without it feeling like a lecture. A new fact appears every ~40 seconds, quietly, below the game. The solstice timing — June 23 is two days after June 21. The jam ends on the solstice. This game is set on that exact day. The connection felt too meaningful to ignore. The mechanics, the visual language, and the narrative are all built around one idea: light persists, even when the world tries to extinguish it. Built during the June Solstice Game Jam, June 2026.

Turing's Light — A Narrative Puzzle Game About Logic, Pride & Legacy

🎮 Play the Game 🔗 Live: https://turings-light.vercel.app 💻 Code: https://github.com/redwanshahriarshubho/turings-light 📹 Demo Video What I Built Turing's Light is a browser-based narrative puzzle game honouring Alan Mathison Turing (1912–1954) — mathematician, codebreaker, father of computer science, and gay man persecuted by the government he helped save. The game spans four acts of his real life across five puzzle levels — every mechanic drawn directly from his actual work. No frameworks. No libraries. Pure HTML, CSS, and JavaScript. The Story Act Setting Level Act I Cambridge, 1930 — Young Alan discovers logic Logic Gates Act II Bletchley Park, 1940 — Breaking enemy codes Caesar Cipher + Binary Decode Act III Manchester, 1952 — Persecution and darkness Light & Dark + Enigma Machine Act IV The present day — His legacy lives on The Turing Test The Five Levels 🔌 Level 1 — Logic Gates Toggle AND, OR, and NOT switches to unlock a door. This is the boolean algebra Turing formalised in 1936 — the foundation of every computer ever built. 📡 Level 2A — Caesar Cipher An intercepted enemy message. Find the shift key hidden in a historical clue about Turing himself, decode the message. This is the cryptanalysis Turing performed daily at Bletchley Park. 💻 Level 2B — Binary Decode Eight binary bytes on screen. Convert each to its ASCII letter, spell the hidden word. Turing proved all information reduces to ones and zeros. 🌑 Level 3 — Light & Darkness A completely dark grid. Click cells to illuminate them — light reveals hidden symbols. Enter the sequence. This level is the emotional core: a metaphor for 1952, when the British government tried to suppress who Turing was. ⚙️ Level 4 — Enigma Machine Six rotors, each cycling A to Z. Dial every rotor to zero — mirroring how Turing's Bombe machine cracked Nazi Enigma codes. The world's first programmable computing device. 🧠 Level 5 — The Turing Test Read two responses to a question — one human, one machine. Decide which is which. Score 4 out of 5 to pass. This is Turing's 1950 paper "Computing Machinery and Intelligence" made playable. How I Built It Tech stack: Pure HTML + CSS + JavaScript. Zero frameworks. Zero dependencies. Opens in any browser. Two canvas layers: Background canvas — animated star field, solstice day↔night sky, aurora effects, floating binary fragments Game canvas — all puzzle rendering and UI state Visual design: WW2 terminal aesthetic — VT323 monospace font, amber phosphor glow, green CRT colours, scanline overlay Pride rainbow runs through the title gradient, HUD, particle effects, and ending aurora Solstice day↔night cycle animates continuously in the game background Story: Four acts of historically accurate narrative with typewriter effect — real dates, real events, real consequences. Solstice Connection The background canvas cycles a solsticeAngle variable, shifting the sky from deep night to pre-dawn and back — a living metaphor for the longest day. The light mechanic in Level 3 makes this literal: your ability to see depends entirely on how much light you bring to the darkness. This is the June solstice theme made interactive. 🏆 Best Ode to Alan Turing Every level mechanic comes directly from Turing's real work: Level Real Turing Connection Logic Gates His 1936 Turing Machine paper — boolean logic Caesar Cipher Bletchley Park cryptanalysis operations Binary Decode Digital information theory Enigma Machine The Bombe — mechanical Enigma decryption Turing Test "Computing Machinery and Intelligence" (1950) The Pride rainbow runs through every screen — not as decoration, but as argument. His identity and his work are inseparable. Honouring one without the other would be dishonest. The ending screen states plainly: he was chemically castrated, he died at 41, he was pardoned 59 years later. The computer you are reading this on exists because of him. Closing Alan Turing asked whether machines could think. He never got to see the answer. The June solstice — the longest day — is a moment of maximum light. For Turing, the light came too late. But it came. His face is on the £50 note. His test names the benchmark for every AI system on earth. "The light of truth can be obscured, but never extinguished." 🎮 Play: https://turings-light.vercel.app 💻 Code: https://github.com/redwanshahriarshubho/turings-light
