A simple game

In this game there will be a set of mahjongg pyramid tiles piled up together. You need to remove the mahjonggs pair by pair until all the mahjonggs are gone. You can match a mahjongg only if it is not blocked from both sides and that it does not have any other tiles stacked above it. When you finish a set, you will be promoted to the next level. There are a total of 3 levels. The faster you finish a level, the higher the score you get.

The classic game of Memory. The object of the game is to turn over pairs of matching cards. Find all the couples in as little time as you can, making as few mistakes as you can to get a high score! And, if you want, you can play against a friend on the same computer!

The object of this game is to rotate the blocks until four blocks of the same kind form the four corners of a square. The square can be of any size and orientation.
