## What is Calvin Chess Trainer?

Master the chessboard from the ground up! Calvin Chess Trainer turns board fundamentals into engaging, hands-on drills designed for young learners.

Chess Notation Trainer
Learn files, ranks, and square names by tapping the board. Three modes let you progress at your own pace: Explore to discover, Practice to build confidence, and Speed Round to test your skills under a 30-second timer. Hear every square spoken aloud as you tap, reinforcing coordinate recognition through sight and sound.

Move Trainer
Read standard chess notation and find the correct move on an interactive board. Drag and drop pieces to solve 500 curated puzzles from the Lichess database. Incorrect? An arrow shows you where the piece should have gone so you learn from every attempt.

Chess Vision Drills
Build board visualization skills with four unique drills:
Forks & Skewers — find the square where a piece attacks two targets at once
Knight Sight — locate all squares a knight can reach in one jump
Knight Flight — navigate a knight to a target in the fewest moves
Pawn Attack — guide a piece through a field of enemy pawns to the other side

Built for Kids
Audio feedback on every tap — files, ranks, and piece names spoken clearly
Streak counter with milestone celebrations at 5, 10, 15, and 20
Personal best tracking across every drill, mode, and difficulty
Hard Mode flips the board to black's perspective for an extra challenge
25+ board themes and 28 piece sets to make it your own

No ads. No in-app purchases. Just chess.

Whether your child is just learning the names of the squares or sharpening their tactical vision, Calvin Chess Trainer makes every drill feel like a game.
