From the README

A fast, arcade-style 4×4 Sudoku for mobile browsers. Instead of writing digits, you eliminate wrong candidates under a 30-second timer while bosses attack your time bar.

Status: in active development. The current build is V1.51.

Play: (works best on a phone, in portrait)

Each cell shows a set of candidate digits. Tap the wrong candidates to remove them; when only the correct digit is left, it locks in. The usual Sudoku rule applies: no digit may repeat in a row, column or 2×2 box.

The interface is currently in Turkish. An English translation is on the roadmap.
