Shapefinder
Shapefinder: a timed shape-pattern practice mode. 20 puzzles, 2 minutes each.
Each puzzle is a 3×3 grid with the bottom-right cell missing. Shape, fill, count and the pointer each follow a rule across the grid; pick the cell that fits all of them. Your score is a separate practice estimate and does not change your rating.
