3D Tetris

3D Tetris is a puzzle game that uses a three-dimensional playing field as opposed to the traditional two dimensions used in most other versions of Tetris. The play field, called a well, contains 5 vertical layers that players fill with falling three-dimensional blocks. These blocks can be rotated horizontally and vertically, as well as positioned in four different directions. Each block displays a shadow underneath it which indicates where it will land.

The game's camera continually adjusts itself, but players can manually readjust it. The HUD displays a radar which provides information about each of the well's five layers, as well as the next block to fall, which is represented by a character. The game contains multiple different modes: 3-D Tetris, Center-Fill, and Puzzle, each having variations in how they play. Players can modify the difficulty in these modes as well as the rate by which the blocks fall.

3D Tetris was developed by T&E Soft and published by Nintendo in North America. A version was planned for Japanese markets entitled Polygo Block, which was to be released in February 1996, but was never released. Like all other Virtual Boy games, 3D Tetris uses a red-and-black color scheme and uses parallax, an optical trick that is used to simulate a 3D effect. The game contains 30 different block types, and renders each one as a 3D wire-frame model until they fall to the bottom of the well, where they are filled in. It was the last game to be released for the Virtual Boy in North America and the last game released overall for the system.

3D Tetris was added to the Nintendo Classics service, including in Japan for the first time under its transliterated American title, on February 17, 2026. D4 Enterprise owns the rights to the game, having acquired T&E Soft's trademark and intellectual property in 2019.

3D Tetris received mostly negative reviews. One common criticism was over the game's 3D perspective and red-and-black visuals. Entertainment Weekly staff experienced eye strain while playing the game, while writer Jeremy Parish experienced headaches. Aaron Curtiss of the Los Angeles Times felt that the 3D effects clashed with the Virtual Boy's visuals, while GamePro writer Scary Larry found its audio and visual presentation minimal.

GamesRadar+ writer Brett Elston found it difficult to tell what was happening because of the visuals. While Next Generation staff argued that all game modes missed the mark due to lacking the "simple elegance" of Tetris, VideoGames staff was less critical. They felt it was less appealing than Tetris due to the 3D effect, but nevertheless executed well.
