What children practice
This puzzle uses X-shape, F-shape, w5, y5, V-shape, longL5, Z-shape, T-shape and bar on a tighter fill target, with a difficulty score of 90 inside its age band.
The tighter fill target leaves fewer forgiving placements, so the child needs to think about what each move leaves behind before committing.
Keep the CTA direct: this page explains the challenge to parents, then sends the child straight into the real board.
What makes this one different: among challenge puzzles in this age band it is the most demanding step, at 90/100. It also introduces five-square pentomino-style pieces.
See What Changes When a Shape Turns? for a parent-readable look at that visible relationship.
Parent observation tip
Before the first move, ask which of the X, F, W, or Y pieces looks hardest to place if left until the end, then let your child test that idea calmly.
Try it when...
Use this puzzle when your child is ready to try a readable Level 1 board and turn a shape before assuming it does not fit. Watch how your child chooses a first piece, tests a placement, and notices when a later piece does not fit.
