The chess tactics trainer that tells you why the winning move
works, not just that it did.
Solve a real puzzle from the Lichess database and the app names the tactical idea behind it,
fork, pin, discovered check and 43 more, then tells you what that idea does on your board: which
piece you moved, which two pieces it attacks at once, which pieces it lined up.
What is in it
7,092 puzzles, matched to your rating or drilled by difficulty.
A motif library of all 46 ideas the app explains, each with your own progress
and a way to practise just that one.
A daily puzzle, the same board for everyone, plus timed sprint and streak
modes.
Weak-spot tracking that resurfaces the motifs you keep missing.
No account required, and every puzzle works offline. Game Center is optional, for
leaderboards and achievements.
