Apple Game is a free puzzle game available as a Chrome add-on that challenges players to enhance their focus and concentration. The objective is to remove apples from a 5x8 grid by selecting numbers that add up to exactly 10. Each apple is marked with a random number between 1 and 9, and players must strategically choose them in straight lines or rectangles to score points.

The gameplay is straightforward yet requires quick thinking and strategy. Players have one minute to score as many points as possible by clicking on the apples. Once the selected apples total 10, they disappear from the board, allowing players to continue their pursuit of high scores. At the end of the game, players can view their final score and have the option to take a screenshot of their board.
