- Chain
- A daily number puzzle. Each day you're given a starting number and a target, and three operations to get from one to the other.
-
- Three operations: Flip (reverse the digits), Boost (multiply by 2), Nudge (add 3). The challenge is finding the shortest chain.
- Every player gets the same puzzle each day so you can compare scores. Includes practice mode for unlimited puzzles and hard mode with longer solutions and limited undos.
- No-backend PWA — puzzle generation, solving, and stats all run client-side. Works offline.
