Think how the pieces will fit together to make a square before you start moving them around. You won't get very far if you don't plan ahead.

Use the memo function to figure out the correct placement for each block. There are four small L-shaped blocks. Three of them form corners of the square.

The T-shaped block goes on the right side of the square, slotted into two small L-shaped blocks. The Z-shaped block goes near the center with the red orb right underneath it.

The small L-shaped block in the bottom left goes one square above its starting position. The large L-shaped block goes directly below it, forming the bottom-left corner of the square.
