What's confirmed and what isn't
The developer, Hungry Studio, hasn't published a full rulebook. To avoid guessing, every rule below is labeled:
- Official: stated in the game's own App Store description.
- Reported: described by an independent gaming publication, but not by the developer.
- Unverified: how the game is commonly described, and what our solver assumes, but not yet confirmed.

The board
The game's App Store description says you “place cube blocks on the 8x8 board.” That's 64 squares in total: 8 rows across and 8 columns down. Every piece you place takes up some of those squares, so the whole game comes down to managing that limited space.
The pieces
Pieces come in many shapes: single blocks, straight lines, squares, L shapes, and more. Pocket Gamer describes them as “3 blocks at a time (of varying shapes, sizes and colours).” The full official list of shapes hasn't been published, so we don't present one here.
Can you rotate pieces? We couldn't confirm this from a reliable source. Most informal guides say pieces can't be rotated, while a few say some versions allow it. Our solver assumes pieces are placed exactly as shown. If your piece looks different, enter it in the solver as it appears on your screen; you can draw any shape.
Order and new pieces. The solver assumes you can place your three pieces in any order, and that new pieces appear only after all three are on the board. Both are common descriptions of the game but haven't been confirmed yet.
Clearing rows and columns
According to the developer, you “complete rows or columns of tiles” to clear them. Columns count just as much as rows, which is easy to forget, and a single piece can sometimes finish both at once. In the example below, one block completes row 4 and column 4 at the same moment.
Starting board
Move 1
Place piece 1 (Single block) starting at row 4, column 4. Clears row 4 and column 4.
- Piece 1: Single block
- Block already on the board
- Piece being placed
- Line that clears
Clearing is how you get space back. Each clear removes a full line of 8 squares, so the board never has to fill up, as long as you keep completing lines.
When the game ends
The game is widely described as ending when none of your remaining pieces fits anywhere on the board. In the example below, 22 of the 64 squares are filled, yet there's no place for a 3 × 3 square or either 5-block line. It isn't how many squares are filled that matters; it's how the empty space is shaped.
- Piece 1: 3×3 square
- Piece 2: 5×1 horizontal line
- Piece 3: 1×5 vertical line
Is every board solvable?
We haven't found anything from the developer saying the pieces you get are guaranteed to fit, or explaining how pieces are chosen. What you can check is a specific board: given your board and your three pieces, our solver tries every order and every position. If they can't all fit, it tells you so and shows how to place as many as possible.
Scoring and combos
The App Store description promises “massive points” and says placing blocks can “trigger chain reactions,” but the developer hasn't published how points are calculated. Online guides disagree, and some describe different games entirely. Rather than guess, we don't list point values or combo rules. What's safe to say: clearing lines frees up space, which keeps the game going, and the developer's own description ties planning to scoring: “Plan your moves to unlock massive points.”
Modes this page covers
These rules describe the classic, endless 8 × 8 game. The App Store listing also mentions “progressive levels with unique jigsaw designs,” a separate mode with its own goals. That mode isn't covered here, and our solver doesn't support it.
