Tetris Gems

The player must move and rotate the Gem-blocks as they are falling down, trying to fit them together. If the player can completely fill one horizontal line with colored gem squares, that line disappears and the player obtains all the animating gems in that line. The level is completed after the player obtains all the animating gems. If the player is unable to fill lines completely, the Blocks will stack up and eventually reach the top of the playing field. The game ends when a new blocks that is placed at the top of the playing field is unable to drop at all due to the filled blocks.

The different blocks of brick:
J-blocks face the opposite direction as L-blocks.
S-blocks for filling small holes.
O-blocks for filling large gaps.
Z-blocks face the opposite direction as S-blocks.
I-blocks are useful for competing four lines at once.
L-blocks for filling medium-sized holes.
