In Guess Tiles, players are presented with a grid of tiles, some of which are covered, and must try to uncover all the tiles in the shortest amount of time possible.
The game takes place in the player's browser and requires no download or registration to start playing. The main challenge is to uncover the covered tiles by making educated guesses, with each guess potentially revealing a blank space or a hidden tile. As the player makes each guess, the grid of tiles is gradually revealed, and the goal is to uncover all the tiles before running out of time.
