About the game
A browser adaptation by Zarocer.
Number Ladder turns a grid into a careful route-planning puzzle. Begin at 1, choose an adjacent square, and place the next number in the sequence. Pre-numbered checkpoints must be reached at exactly the right step, so a tempting shortcut can leave you with nowhere to go. The twelve-level journey grows from compact 3 × 3 boards to 6 × 6 puzzles. Practice lets you choose a board size, while the daily challenge gives everyone the same 5 × 5 board for the UTC day. Hints, undo, and saved games help you explore a puzzle at your own pace. Assisted and restored attempts remain local and are excluded from competitive submission. Play with a mouse, keyboard, or touchscreen, with eleven languages available inside the same game build.
Controls
Begin at the square marked 1. Select an adjacent square to place the next number. Move horizontally or vertically, never diagonally. Visit each square once and reach every numbered checkpoint at its indicated step. Fill the board to win. If no legal step remains, undo to explore another route or restart. Use arrow keys to move focus and Enter or Space to select. Escape opens pause.
