Count in L-shapes, discover squares

Instead of counting row by row, count in L-shaped layers from the corner. Each layer adds an odd number of cells — and the running total is always a perfect square. Look at the top row of the grid. What's special about them!

Layer by layer

1 = 1 = 1²

1 + 3 = 4 = 2²

1 + 3 + 5 = 9 = 3²

1 + 3 + 5 + 7 = 16 = 4²

1 + 3 + 5 + 7 + 9 = 25 = 5²

▶ Start

First row = perfect squares
