Brain Games are one-minute drills that each isolate a single chess skill, the way a gym machine isolates a muscle. They train the perception that comes before calculation — seeing which squares are covered, which pieces are loose, where the king can run — so that in real games you stop missing what was right in front of you. No other major chess platform (Chess.com, Lichess, Chessable, Aimchess) has a drill category like this. Every game takes exactly one minute, and your scores feed the same profile as your analyzed games, so your vision training and your weakness training point at the same target.
The games
Coverage · 1 min
A position appears; you identify which squares are attacked and which are safe — fast. Coverage trains raw board vision, the skill behind every "I just didn't see it." Strong coverage reading is the difference between calculating three moves and blundering in one. Maps to the real-game mistake: moving a piece onto a defended square. Play Coverage →
Knight Taxi · 1 min
Route a knight across the board to a target square in the fewest moves, again and again, against the clock. Knight paths are the hardest geometry in chess to internalize; Knight Taxi makes them automatic, so knight forks start appearing to you — in both directions. Maps to: missed knight forks, slow knight maneuvers. Play Knight Taxi →
Hanging? · 1 min
One glance, one decision: is that piece defended or hanging? Undefended pieces decide more club-level games than any opening ever will. This drill compresses "count the attackers and defenders" into an instant reflex. Maps to: hanging your pieces, missing free captures. Play Hanging? →
Escape Squares · 1 min
Read the king's safety at a glance by finding its escape squares. Players who can count flight squares instantly see mating nets — theirs and their opponent's — moves earlier. Maps to: walking into back-rank mates and mating nets. Play Escape Squares →
Free Material · 1 min
Find an undefended piece you can capture safely. Play Free Material →
Coordinates · 1 min
Find the named square, fast. Play Coordinates →
Mate-in-One Rush · 1 min
Deliver mate in one, over and over, against the clock. Play Mate-in-One Rush →
Remove the Defender · 1 min
Remove the defender, then capture the target it protected. Play Remove the Defender →
Find the Pinned Piece · 1 min
Find pieces pinned to their king or a more valuable piece. Play Find the Pinned Piece →
Pressure the Pinned Piece · 1 min
Add an attacker to the pinned piece, then complete the capture. Play Pressure the Pinned Piece →
Fork · 1 min
Fork two pieces with your knight, then capture the remaining target. Play Fork →
Why one minute works
A minute is short enough to do while the kettle boils and hard enough to matter when it's the right minute. Each Brain Game is scored, streaked, and spaced: the games you're weakest at come back more often. Do three a day and you've spent less time than one blitz game training the exact vision that decides your blitz games.
Brain Games FAQ
How do Brain Games make me better at real chess?
They train perception, not memory. Blunders at 800–1400 mostly come from not seeing — a loose piece, a covered square, a knight's reach. Brain Games compress those sights into one-minute reps until they're reflexes, and your scores feed the same weakness profile as your analyzed games.
Are Brain Games on Chess.com or Lichess?
No. Chess.com and Lichess have puzzles and puzzle-rush modes, which train calculation under time pressure. Brain Games train the perception before calculation — square coverage, piece safety, knight geometry, king safety — in 60-second single-skill drills. The category exists only on Mainline.
Do Brain Games cost anything?
No. Brain Games are part of Mainline, and Mainline is free.
