NumShift - Number Puzzle

NumShift is the classic 15-puzzle reimagined with a clean modern design. A four by four grid holds fifteen numbered tiles and one empty space. Swipe any tile next to the empty space and it slides smoothly into the gap. Your goal is to arrange all tiles in numerical order from 1 to 15 left-to-right and top-to-bottom with the empty space in the bottom-right corner. Four difficulty levels control how deeply the puzzle is scrambled before you start. Easy gives you a lightly shuffled grid you can solve in a few moves. Medium is a proper challenge. Hard requires careful planning. Expert is a deep scramble that will test even experienced puzzle solvers. A move counter and timer run throughout your session and your best move count for each difficulty is saved so you can always try to beat your personal record. Completing the puzzle in fewer moves earns more stars.
