Chess Brain Trainer
Puzzles built on how the pieces move. Not openings, not endgames — board vision: where a piece can go, what it attacks, and which square is safe.
Three modes
- Sleepers — capture every black piece, and capture on every turn. The pieces never move; the difficulty is the order. One wrong move blocks the path you needed.
- Avoidance — capture them all without ever standing on a square they attack. Quiet moves are allowed, but the danger does not go away.
- King Hunt — remove the black king's defenders first, then the king himself, with the black pieces lurking the whole time. The hardest of the three, and the one that punishes guessing.
Who it is for
Beginners learn the movement of each piece by using it, without the pressure of a whole game, and build board awareness one piece at a time.
Experienced players get calculation speed and pattern recognition under constraints that do not occur in ordinary play — which is exactly why they are useful practice.
Free, and what Premium adds
All three modes, every difficulty and all 18,000+ puzzles are free. No advertising, and no limit on how much you play.
Premium is a one-time purchase and adds:
- Progress history — how much you practised day by day, and how you are doing in each mode.
- Mistake log — replay exactly the puzzles you did not solve.
- Custom training — pick the mode, the difficulty, the session length, and whether the clock is shown.
Premium gives you insight into your own practice, never an advantage in it.
Scoring is the same for every player.
