Neon Tetris
Stack the falling blocks and clear the lines.
Neon Tetris is the block-stacking classic. Move the falling pieces left and right, rotate them and drop them to complete full rows, which then clear for points. It speeds up as you clear more lines — do not let the stack reach the top.
Controls: arrow keys on desktop; on a phone tap left/right to move, top to rotate, bottom to drop. A demo game by the GameFoundry team.
