15 Puzzle: Sliding Numbers

GEMDUCK LIMITED

About this game

Slide numbered tiles into order, using just one empty space. Begin with 40 small 3 × 3 sliding number puzzles, then continue through 80 classic 4 × 4 fifteen puzzles. Every starting position is produced by legal moves from the finished board, so every puzzle can be completed. Correctly placed tiles get a gentle color cue. There is no countdown or move limit.

WHEN YOU WANT A LITTLE HELP
