How to Solve Brain Test 4 Level 331 — Full Solution
- Drag the lime-green L from the upper-right into the central 2x2 frame so it fills the top-left, top-right, and lower-right cells.
- Drag the red multi-square piece from the upper-left down over the yellow L at the lower-left, then release.
- Confirm that the yellow L contracts to one yellow square while the red piece returns to the left.
- Drag the remaining yellow square into the empty lower-left target cell.
- Wait for the complete green-and-yellow target, the large green check, and the completion card.

Common Mistakes to Avoid
- Trying to fit the entire yellow L into the four-cell target.

- Stopping after the green L fills only three target cells.
Quick Tips for Brain Test 4 Level 331 (quick clues)

Board notes 5 details
- Layout
- A gray-framed 2x2 target is centered between a lime-green L at upper-right, a yellow L at lower-left, and larger red and cyan pieces on the left and right.
- Goal
- Fill all four target cells: green in the top-left, top-right, and lower-right cells, then yellow in the lower-left cell.
- Opening
- Drag the lime-green three-square L from the upper-right down-left into the central frame without rotating it.
- Danger Zone
- The cyan piece is a decoy, and the whole yellow L is too large for the target; first drag the red piece over the yellow L so it contracts to one yellow square.
- Mechanics
- The red polyomino transforms the yellow polyomino when it is dragged over it, leaving the single tile required by the target.
