How to play.

Each puzzle gives you a square grid of tiles (3×3, 4×4, or 5×5). The grid has two axes: one for rows and one for columns. Arrange the tiles so every row and every column is in order.

Pretend the puzzle is fruit. The horizontal axis is size (smaller on the left). The vertical axis is rainbow position (red at the bottom, purple at the top). Here’s a solved board:

Take any single row. Reading left to right, the tiles must follow the axis shown along the bottom — here, size, smallest to biggest. The bottom row goes cherry (small) → strawberry (small-medium) → peach (medium).

Same idea for any column. Reading bottom to top, the tiles must follow the axis shown down the left side — here, rainbow position, red end to purple end. The right column goes peach (orange) → watermelon (green) → grapes (purple).

Below, the pear and the lemon have been swapped. The columns still read fine — but the middle row now goes pear (big) → lemon (medium) → watermelon (biggest), which isn’t small-to-big. One bad pair is enough to fail the row:

Swap them back and the row is in order again. The same idea applies to columns — every column must read red-end to violet-end going up.
