If a block is placed in a layer's center block, it disappears, and any other blocks in the layer will also disappear if they have been successfully placed in a symmetrical pattern. In the Center-Fill mode, the player places blocks in symmetrical patterns around center blocks placed in each of the Well's layers. One of its gametypes, "Type A", requires the player to gain as many points as possible, and its other gametype, "Clear It!", contains multiple stages which the player progresses through by clearing five layers on each stage. The game is over when the final layer is lost. If blocks stack over the top of the Well, the number of layers will go down by one. In the 3-D Tetris mode, a layer disappears when it's filled with blocks, scoring the player points which are displayed in the HUD. Each mode's 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 "block character". The game's camera continually adjusts itself, but the player can manually readjust it. Each block displays a shadow underneath it which indicates where it will land.
Each mode contains a "Well", which itself contains 5 vertical layers that the player must fill with falling three dimensional blocks that can be rotated horizontally and vertically, as well as positioned in four different directions. The difficulty changes which types of block fall. The player can choose multiple different levels for each of these modes, which change the speed at which the blocks fall, as well as choose three difficulty settings easy, medium and hard. The game contains multiple different modes "3-D Tetris", "Center-Fill" and "Puzzle", each having different gametypes. 3D Tetris is a puzzle game that uses a three-dimensional playing field as opposed to the traditional two dimensions used in other versions of Tetris.
