QuadRead the target
The small grid above the board shows the exact color pattern you need to reproduce.
The basic rules
Choose a square block
Each selectable block contains four tiles. Tap it to rotate those tiles 90 degrees clockwise.
Plan linked movement
If gears connect blocks, one tap can rotate more than one block. Check every linked area before committing to a move.
Match the complete pattern
The level is solved when the playable board matches the target within the time and move conditions.
Improve your star result
Replay completed puzzles and solve them with a more efficient move count to work toward three stars.
What changes in advanced levels?
GEARS
Linked blocks
A rotation can affect a partner elsewhere on the board. Treat linked blocks as one system rather than separate pieces.
COLOR STATE
Color inversion
Some levels let a block switch between the two puzzle colors. This changes tile state without using the normal clockwise rotation.
EFFICIENCY
Move planning
A solution can be valid without being optimal. Fewer unnecessary turns lead to stronger star results.
Practical strategy
| Situation | Useful approach |
|---|---|
| A gear move fixes one block but breaks another | Compare both linked blocks to the target before rotating. Plan the pair as a combined state. |
| A block appears correct early | Do not assume it should never move again; later gear rotations may require a temporary mismatch. |
| You are using too many moves | Work backward from the target and count how many quarter-turns each independent block needs. |
| The board becomes hard to read | Use undo to test a sequence safely, or use a hint to reveal a useful next action. |
Gameplay questions
What does tapping a block do?
It rotates the four tiles inside that square block 90 degrees clockwise. Connected gears can make other blocks rotate too.
How is a level completed?
Every tile color and orientation on the board must match the target pattern shown above it.
What are hints and undo for?
A hint reveals a useful next action. Undo reverses your previous action so you can try a different sequence.
Is QuadSpin the same as a classic block placement game?
No. You do not drop pieces or clear lines. The challenge is changing the state of blocks already on the board.
