WHO IS PUZZLEMATE FOR?
For chess beginners who want a structured way to learn chess tactics. For club players between 1200 and 2000 ELO who want to close their tactical gaps. For advanced players who want to train visualization through Ghost mode. For anyone looking for a quiet, focused chess trainer without noise.

HOW DOES THE CHESS TRAINING WORK?
You start with an ELO rating per tactical theme (fork, skewer, discovered attack, mating nets, and more). After every solved chess puzzle, PuzzleMate adjusts the difficulty – correct solutions raise your ELO, mistakes lower it slightly. This way you always get chess puzzles right at your learning edge: hard enough to challenge you, manageable enough to see progress.

The Glicko-2 calculation considers not only success or failure, but also your confidence while solving. Solving a puzzle quickly and cleanly earns more ELO than reaching the solution after several failed attempts.
