3D Tetris

Game Details:

The core mechanics of "3D Tetris" are similar to the 2D version, but the operational and strategic dimensions are greatly increased. The game scene is a five-layer deep cylindrical 3D "well", with various shapes of 3D blocks constantly falling from the top. Players must use the Virtual Boy controller's D-pad to move blocks horizontally, rotate blocks in four directions, and rotate blocks on the vertical axis. Shadows below the blocks indicate their final landing point, which is crucial for precise placement. The game has three main modes: "3D Tetris Mode" is the main mode, with the goal of eliminating filled layers and accumulating points; "Center-Fill Mode" requires players to symmetrically place blocks around a central preset block; while "Puzzle Mode" requires players to use the given blocks to precisely match a preset specific shape. When the blocks stack up beyond the top layer of the well, the game will trigger a penalty or end directly depending on the mode, which requires players to maintain a clear understanding of the five-layer spatial structure at all times.

Game Walkthrough:

• The clever use of vertical rotation (Z-axis rotation): Many players focus on horizontal rotation (X/Y axis), but vertical rotation is key to clearing internal voids and adjusting the orientation of blocks. For example, a long rectangular block may not be able to align with the target gap after horizontal rotation, but by vertical rotation, it can be changed from a "lying flat" state to a "standing" state, more precisely filling single-grid spaces deep within.
• Plan the bottom three layers in advance: The game well is five layers deep, but the difficulty of operation increases sharply when blocks are stacked to the fourth and fifth layers. Therefore, an efficient strategy is to send blocks to the bottom as early as possible and strive to complete as many layer eliminations as possible in the bottom three layers. Once there are voids in the upper layers, it becomes very difficult to clear.
• The symmetry principle of "Center-Fill Mode": In this mode, blocks must be placed symmetrically with the center block as the axis to eliminate. This requires players to have a complete mirror plane in mind when placing blocks. Usually, the best approach is to first place a center-symmetric block, and then place the asymmetric blocks on both sides in a symmetric manner. The goal of "Center-Fill" is to form a perfect circle or square around the central axis, rather than the traditional sense of completely filling.
• Reverse thinking of "Puzzle Mode": Puzzle mode requires you to use randomly falling blocks to reproduce the preset shapes of the game. This is not a mode that pursues speed, but rather examines spatial analysis ability. First, take a few seconds to carefully observe the target shape and identify its most unique and irregular parts. Then, determine which falling block is best suited to fill that unique part. Start with the most difficult-to-fill gaps, rather than starting from the easy-to-fill edges.
