About Blockout

Blockout is a puzzle videogame, created in 1989 by Polish developer - California Dreams, designed by Aleksander Ustaszewski and Mirosław Zabłocki. The game is the logical extension of Tetris into the third dimension. In Tetris, the player manipulates a set of tetrominoes which fall into a two-dimensional pit (seen from the side). The aim is to solve a real-time packing problem by forming complete rows, which then disappear and score points. Poor play leads to incomplete rows, caused by inefficient arrangements of tiles; these rows do not disappear, giving the player progressively less space and less time to play subsequent pieces. Similarly, in Blockout, the player manipulates a set of polycubes which fall into a three-dimensional pit (seen from above; the pieces appear in the foreground and fall away). The pieces can be rotated around all three axes, and moved horizontally and vertically. The aim is to form complete layers.

Three-dimensional Tetris, years before 3-D Tetris tried it on the Virtual Boy — and a better version.

P.Z.Karen Co. Development Group handled the conversion of the California Dreams original, with Atari publishing in 1991. You rotate falling polyominoes around three axes to fill layers in a pit, with the field size adjustable to set the difficulty — a properly hard, properly good puzzle game that period writers described as taking the Tetris idea into its next generation rather than merely copying it.

Worth noting alongside the Virtual Boy’s 3-D Tetris, which attempted the same idea five years later on stereoscopic hardware and is generally rated lower. Never re-released — and one of the five titles Atari gave away in its 1993 Two-Fer promotion, which is part of why it is among the cheapest carts here.
