Heatmap Chess

Read full description

Heatmap.Chess teaches you to read a chess board the way grandmasters do โ€” as a map of control, not a list of pieces. EVERY NUMBER IS A THREAT Each square shows how many pieces want to attack it. A "3" means three pieces are converging on that square. Drop your dock pieces in the right places, and every correct placement cools the heat by one. Get all numbers to zero โ€” puzzle solved. WHAT'S INSIDE โ€ข Hand-crafted themed rooms with graduated difficulty โ€ข Fresh daily puzzles โ€” keep your streak alive โ€ข Heart system + combo bonuses โ€ข Cross-device sync โ€” pick up where you left off โ€ข Quiet, focused dark UI built for one hand โ€ข One-time purchase removes ads + unlocks every room SHARPEN YOUR CHESS VISION No openings to memorize, no notation to decode. You start seeing what grandmasters see when they sit down at a board โ€” the geometry of attacks. A training tool for beginners and experienced players alike. DESIGNED FOR FOCUS No social feeds. No leaderboards screaming at you. Just numbers, pieces, and the small satisfaction of every count dropping to zero.
