A quiet board, with useful depth when you need it.
Everything is designed to keep the puzzle central. Controls remain close at hand, while statistics and detailed reasoning stay available without competing for attention.
More than an answer
When a technique needs several steps, the game records the relevant candidates, source cells, shared units, and exact eliminations that produce the result.
Fast, varied puzzles
Ten thousand carefully validated source puzzles and safe transformations provide enormous variety without making you wait for puzzle generation.
Hints that explain themselves
A logical hint shows the technique, relevant cells, and exact eliminations. Keep the explanation open while you study the board and learn the reasoning.
Tools that stay out of the way
Notes, undo and redo, meaningful difficulty levels, local statistics, themes, and keyboard support—without clutter.
Private by design
Your game, settings, and statistics stay on your device. There are no ads, analytics, accounts, or tracking.
