Stemettes Cipher Challenge

Register for this event

Ever wanted to crack a secret code, or build the puzzle that stumps everyone else?

Ciphers & Quests is a one-day STEAM hackathon on Saturday 30 January 2027, from 9:45 am to 5:00 pm in London, for girls, young women and non-binary people aged 5 to 25. You’ll work in a team to decode secret messages and build games and puzzles around them, choosing the challenge that suits you. With different challenges to suit you, you can build a game in Scratch or MakeCode Arcade, learn different ciphers and crack coded messages, or design a cipher-based escape room using Figma and Thunkable. Plus, goody bags, lunch, and all the tech provided!

“I enjoyed working with other people, sharing ideas, and building a project in a creative environment where everyone was encouraged to experiment.” – Heebba
