In Tetris, you have seven tetraminos to put clear lines with. Once you complete a line, it is cleared and all of the blocks above it fall down. Tetris has an odd gravity. When lines are cleared, every block moves down an equal number of grid spaces to the lines that were cleared. They don't fit into spaces to make chains or anything, they may just float in midair.
