Tetrominoes... where do they come from?

Move the peg around to swap its position with a neighboring tile.

When you make a move, there are 3 possible outcomes:
Good Move:
You made a tetromino. +1 on your score.
Free Move:
The tile you moved connects to one of its kind.
Bad Move:
The tile you moved is isolated. -1 on your bad move gauge.

In Twenty mode,
you are allowed 20 bad moves until the game ends.
In Marathon mode,
you start with 4 bad moves and gain one for each tetromino you make.

8 game presets:
2 modes (twenty & marathon) x 4 sizes (5,7,9,11)
