N-Blox is similar to Tetris 1989. It does not use many of the new features such as the hold function and the four block preview. Players are also not allowed to change the keyboard controls, which they can in every other mode. The goal is to score as many points as possible. The speed increases after a certain number of lines are cleared. This is similar to other standard Tetris modes available in other games.

A handheld game licensed by The Tetris Company and produced by Hasbro, this game features two LCD screens, with the smaller one on the shorter end and the wider one going around the body of the main unit. Game-play consists of the player twisting the shorter end to position the piece projected on the smaller screen above the gap in the pieces shown on the larger, twisting the smaller screen itself to rotate the piece itself in one direction or another, then squeezing both ends together to "drop" the piece in place. On Marathon Mode the player is given three lives, and the time allotted the player to maneuver, rotate and drop the piece gets shorter as the game progresses. Should the player either fail to drop the piece in time, or they drop said piece in a way that any part of the piece would stick out of the top of the lower LCD screen, the player loses a life.
