GameJam Cipher

June Solstice Game Jam Submission

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.

☀ 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. A night sky brightens into dawn as your accuracy rises, a Pride rainbow…

How I Built It

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.
