How it trains you
- Puzzles at your level
You answer one question when you start: how much chess have you played? After that your rating does the work — solve a hard one and it climbs, miss an easy one and it drops, and the puzzles follow.
- Real positions, real lines
Every puzzle comes from a played game. The opponent moves first, then you find the line that works — move by move, not one clever move and done.
- Mistakes come back
Miss a puzzle and it goes on your review list, so the tactic you did not see gets a second attempt later instead of disappearing.
- A daily puzzle
One puzzle a day, the same one for every player. Train on any day and your day streak grows; only skipping a whole day breaks it.
- Fully offline & private
All 100,000 puzzles ship inside the app. Your rating, stats and history stay on your device — there is no server of ours for them to go to.
- No subscription, ever
Free to play with kings as your training lives. They refill on their own, and a single one-time purchase unlocks unlimited play and removes every ad.

Stats that tell you something
Your rating over time, how many puzzles you attempted and how many you got right, how long you take, your best streaks — and accuracy per motif, which is the one that earns its place: it shows at a glance that your pins are fine and your deflections are not.
Ten minutes of tactics a day
Beats an hour of watching someone else play. Pick up where your rating sits and start solving.
