Start at 1, then connect 2, 3, 4, and every hidden step in order.
Ordinal Trace is a calm number-order logic puzzle. Every number belongs on the board, but some are hidden inside dashed circles. Use the visible clues to infer each missing number, then trace one continuous path from smallest to largest. Neighbors may touch horizontally, vertically, or diagonally.

Learn on compact 3×3 boards, then work up to 12×12 challenges with more hidden numbers. Later levels span multiple connected boards, while mistakes cost lives.
