In the PS2, PC, and GBA versions, gameplay contained one major difference from a normal Tetris game. In classic Tetris, when a Tetrimino touches the bottom of the screen, it locks in place. However, in these versions, Tetriminos do not lock until players make them lock (e.g., by using Hard Drop to lock them immediately), allowing players to rotate and move the pieces indefinitely until they are satisfied. Critics said that this made the game too easy (although the countdown clock still runs while the player is using unlimited move and rotate) and "GameSpot" said that it "broke Tetris". However, the GBA version features a hidden version of classic Tetris (titled "Popular" Tetris) that plays without this feature. It is accessed by holding the L button and pressing select on the "Marathon" game select menu. However, since it is not part of the "Default" presentation, many reviews did not factor in this mode.
