Cresset

A puzzle of signal fires — pure logic, no guessing.

Place one fire in every row, every column and every colored region. No two fires may touch, not even diagonally. Every puzzle has exactly one solution and is solvable by deduction alone. When you solve the board, day turns to night and your fires ignite.

• Classic — a generated puzzle with a guaranteed unique, guess-free solution.
• Daily — the same board for every player worldwide, every day. No account.
• Endless — an infinite strip of puzzles; solved land sinks into night behind you.

Pay once, own it: no ads, no in-app purchases, no subscriptions, no tracking. Offline-capable. Colorblind-friendly (every region carries a glyph as well as a color).
