What is My Chess Puzzles (Chess Tactics)?

The app is based on solving chess problems. There are over 100 different puzzles in the app. The game is played on a board that has 64 squares arranged in an 8×8 grid. Each square can be occupied by a piece with a value of either 1, 2, 4, or 8. A puzzle consists of placing the pieces on the board so that they form a valid legal chess move.

When you are solving a puzzle, you are trying to achieve the desired result by making the best move. If you make the wrong move, the game will automatically try to find the best move that will achieve the desired result.
