ClickPuzzle offers you to destroy a wall made of tiles to discover a picture behind it.
Tiles can’t be removed separately but in combination with other identical tiles. You have to identify a block of tiles and click on it. The program can highlight the blocks for you when moving the mouse cursor over them to facilitate the game.
The game is highly customizable. You can make it easier or harder to play by selecting the total number of tiles and the number of their types, and deciding whether the tiles should shift to the right when they fall down or not.
Several sets of tiles in different styles are available, such as flowers, signs, primeval art, etc. You can also choose the size of tiles but larger tiles tend to lose sharpness, so the default size seems to be optimal in most cases.
If you just randomly click on the groups of tiles you may have many tiles still remaining at the end of the game. It’s reasonable to think the steps through in advance to remove as many tiles as possible. Time and points are counted as you play so that you can try to improve your results next time or compete against friends.
