Monos is a puzzle game with Tetris-style controls and irregular coloured shapes for the players to place inside a well. The level count increases by one for every ten shapes cleared from the screen, and there are a total of fifty levels to play regardless of the difficulty setting chosen.

Your objective is basically to match two or more blocks of the same colour to remove them. The Z and X keys can be used to rotate the current piece in play. Press up to place a block at the bottom of the well immediately, or hold the down arrow key to move it downwards at a slower pace.

In the percent gameplay mode, players are given random shapes to fill a well with. The more shapes you can fit in, the higher your percentage count will be at the end of the game. (direct download link)
