The game begins with a grid of tiles, each bearing a stamp image. The player's task is to match identical stamp images across adjacent tiles.
The core mechanic involves sliding tiles horizontally or vertically to create combinations of matching images. Each successful match results in the removal of the matched images, freeing up space for new ones to emerge. The player's goal is to clear the grid by making these matches.
The game features an increasingly complex grid as it progresses, requiring the player to think strategically about each move. It can be played directly in the browser without the need for a download or registration, allowing players to jump in and start solving puzzles immediately.
