Checkmate: Chess Puzzles

Checkmate Master — hone your tactics with 100 forced mate problems.

Find the winning move. Every position ends with a forced mate:
find the correct sequence, finish the game, and earn your stars.

100 verified problems
All 100 positions have been individually checked to provide a
clear solution, without ambiguous variations. The difficulty ranges from mate in 2 moves to
demanding 8-move combinations.

Gradual difficulty
As you progress, you'll recognize classic patterns: back-row mate,
smothered mate, sacrifices, deflections, and decoys. Ideal for practicing
a few minutes a day, whether commuting or at home.

Play offline
The problems work without an internet connection: on a plane, subway, or anywhere
without a network. No account or registration is required; your progress
is saved on your device.

Customize the chessboard
Choose from several chessboard themes and piece appearances

(classic wood, modern flat design, high contrast, and more). The clean interface
keeps the focus on the position.

Stars, points, and progress
Earn stars for your solutions and accumulate points by
completing each level. A difficulty curve designed to build
transferable skills on the chessboard.
