Nearly all falling block games are capable of showing a preview of the next piece to enter the playfield. The next pieces are displayed in a window of the tetrion, generally positioned to the right of or above the playfield.
Game start |
O enters; J is next |
Player drops O |
J enters; next is T |
Player drops J |
T enters; next is Z |
Some of the older games gave more points if the player chose to turn preview off.
Many Tetris games released since 2001 show 1 to 6 next pieces.
