# GameJam Cipher > Source: > Published: 2026-06-19 00:30:05+00:00 *This is a submission for the June Solstice Game Jam* 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. 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. 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.** A night sky brightens into dawn as your accuracy rises, a Pride rainbow… I built it using ReactJS and hosted on vercel. I implemented a simple frontend with no backend dependency session-specific experience for simplistic approach Using hardcoded values and configuration.
