A card math puzzle game — combine playing-card values with + − × ÷ to reach the target.
A full-stack number puzzle game built with Next.js. Each puzzle gives you a target (1–200) and a hand of card values (ranks 1–13). Select two tiles, apply an operator, and merge them until a single tile equals the target.
Practice mode is untimed and runs entirely in the browser. 5-Minute Sprint is a competitive solo mode with server-tracked scoring and a persistent leaderboard. Multiplayer lets you create or join a room (public or password-protected), share an invite link, and race friends on the same puzzles under a shared timer — whoever solves more wins.
