How to play
There are 2x2-blocks falling down the top, with two different colors. The objective is to rotate and align the falling groups of blocks to create squares of the same block color once the blocks have landed.
A vertical line, known as the time line, sweeps through the playing field from left to right, erasing any completed single-color groups of blocks that it touches (typically 2×2 squares).
By default, Loonies 8192 has synthesized sound built in, but it's possible to also use CD-quality audio files.
Download the Loonies 8192 Sound Pack, and put the WAV files in the game folders for 3DS to upgrade your sound experience to fully sampled 16-bit audio.
