Searching for 3D Tetris? Here is what Cubo actually does
People type that phrase looking for blocks in three dimensions. Cubo is blocks in three dimensions, but it is a fitting puzzle rather than a falling one. Worth knowing before you install it.
Free on iPhone.
What you might be expecting, and what is here
| If you came looking for | What Cubo does |
|---|---|
| Pieces that fall | Pieces sit in a tray. You pick one, turn it and place it when you are ready. |
| Speed that ramps up | Nothing accelerates. Speed mode counts your seconds, it does not push you. |
| Clearing lines or layers | Nothing clears. Placed pieces stay, and the box filling up is the goal rather than the danger. |
| Game over when the stack tops out | No losing state at all. A round ends when every cell is filled. |
| An endless run for a high score | Discrete rounds. Each solve gets a score and a time, then you start a fresh board. |
| Rotating a shape to make it fit | That part is the whole game, in three dimensions rather than two. |
What carries over
If what you actually like about a falling block game is the moment a shape clicks into the only place it could have gone, that instinct transfers directly. Cubo asks the same question with more axes: the box on Medium and Hard is two layers deep, so a piece often has to be turned out of the flat plane before it fits.
- Short rounds. Easy is a four by four box, one layer, four pieces.
- A clock, if you want one. Speed mode records a best time per difficulty on the device.
- Something new every round. Boards are generated rather than drawn from a fixed level list.
The part a falling block game cannot give you
Every Cubo board is made by cutting a filled box apart, so a solution is guaranteed to exist. When a board looks impossible it is not the board, and that changes how it feels to be stuck: the piece is in your hand, the space is on the screen, and the arrangement is somewhere in the 24 orientations you have not tried yet.

Falling block questions
Do the blocks fall in Cubo?
No. Pieces wait in a tray at the bottom of the screen until you choose one. Nothing descends, nothing speeds up over time, and no piece arrives that you did not ask for.
Do you clear lines or layers?
No. Nothing is removed from the board once it is placed. The round moves in one direction only, which is towards a full box, and finishing the box is the win.
Is there a game over?
No. There is no stack that reaches the top and no way to lose. If a board is not working out, the restart arrow gives you a fresh one at no cost.
Is it still about fitting shapes under pressure?
It can be. Speed mode runs a clock and scores the solve, which is the closest thing here to a falling block game. Relaxed mode drops the clock and leaves the fitting.
What makes it three dimensional?
The pieces are blocks of connected cubes rather than flat shapes, and the box on Medium and Hard is two layers deep. A piece has up to 24 distinct orientations, so turning it out of the plane is often the move that makes it fit.
