The aim of the game is to stack blocks into the pit without gaps. Full layers disappear.
The "active" block is displayed as a white wireframe. Rotate and move the
active block so it fits into the pit without gaps. The game ends when the pit
Tap-and-drag the yellow controls to move the block.
- Left control
- Use the inner ball to rotate the block out of the screen
plane (pitch and yaw). Use the outer wheel to rotate the block within the screen plane
- Right control
- Drag the ball to shift the block left-right and up-down
- Double click anywhere on the screen
- Drop the ball to the ground
Alternatively, you can move the block by directly touching the game field.
- Single-finger swipe on the block
- Rotate the block out of the screen plane
- Single-finger swipe around the block, or two-finger twist
- Rotate the block within the screen plane
- Two-finger swipe or (on capable devices) force-touch-swipe
- Shift the block left-right and up-down
You earn a little score for each dropped cube. However, to reach a really
high score you need to create full layers. As soon as a layer is full it will
burst (disappear) and you'll get points.
- You'll get more points when you burst many layers at once
(double-burst, triple-burst or quadruple-burst, also called a "qubotron").
To achieve a multi-burst, build up a stack of layers but leave one grid
position empty. Then, wait for a 3x1x1 block (a "bar") and fit it into
the empty position.
- After each minute of gameplay, the level is increased by one. The higher
the level, the faster the active block will fall down, increasing time pressure.
The good thing is that you will also get more points in higher levels.
For the same action (e.g. a layer burst) you will get three times more points
in level 3 than in level 1. Hint: You can select the start level in the
game options according to your skill, so you can earn more points right from
the start without having to go through the lower (easy) levels.
You'll get additional points for special moves like the "eclipse" and "eclipse burst",
known elsewhere as "T-Spin" moves.
An "eclipse" is when you first create an overhang (i.e. a void
space under another block),
and then manouver the active block into this overhang from the side.
After you drop a block (by a double-click) you still have a grace period of
half a second or so to rotate/shift the block.
Use this to shift the active block to the side into the overhang quickly after dropping it.
An "eclipse burst" is when this results in the completing of one or more layers.
This can be only done by rotating a block (preferrably a T-shaped block) after
dropping it. A more detailed explanation is found here:

A scientific study with teenagers showed that games like this can improve the spatial sense
. The study was
conducted using a
quite similar game, the DOS game Blockout
from the 90s.
In this study with more than 100 kids, half of the kids got the opportunity to play Blockout
during summer vacation, the other half did not. The spatial sense of all kids was
tested before and after the vacation using a standard test procedure (Gittler 3DW Test).
The kids having played the game improved significantly compared to the kids not having played the game.
