This is a puzzle game where players try to complete filling in the puzzle field given a set number of colored pieces. Touch the screen or click on your mouse to select a piece and drag it where it belongs on the puzzle playing field.

- Blocky is not timed.
- When pieces are placed correctly they exactly fill in the playing field.
- Pieces can not be turned, making the game quite easy to play as there are a limited number of potential placement combinations.
- Pieces can easily be removed from the playing field if you make an error.
- Each piece can appear in exactly one location.
- Levels get progressively harder as you work your way through the game.
