Slide Puzzle Speedrun

Yeet those tiles into place! Slide Puzzle Speedrun turns the classic 15 puzzle into a race against the clock. Scramble, solve, and chase your best time on a silky 120 Hz board. Then watch your run replay side by side with the optimal solution, and see every wasted move. FOUR WAYS TO PLAY • Standard: One fresh scramble. One time. Go. • Marathon: Ten boards back to back on one clock. Pace yourself. • Blind: Study the board, make your first move, and the numbers vanish. Solve it from memory. Peek if you must. • Daily: One board a day, the same for every player. It flips at midnight Eastern. Check yesterday's board to see your best run next to the optimal solve. KNOW EXACTLY HOW GOOD YOU ARE • An on-device solver finds the fewest-move solution for every scramble in a blink. • Replays put your run next to the optimal path, with your efficiency and a moves-to-solved chart. • Every board gets a difficulty rating, from Easy to Brutal. • Every scramble is fair: drawn evenly from all 10,461,394,944,000 solvable positions. BUILT FOR SPEED • Metal rendering at up to 120 Hz on ProMotion displays. • Tap, Swipe, or Hover controls. Pick your style. • Five tile themes, from bold Fringe to clean Mono. STATS THAT KEEP YOU HONEST • Best, mean, moves, TPS, a time histogram, and a practice calendar. • Flip on Stats for Nerds for mo3, ao5, ao12 and beyond, with the standard WCA-style trim and rolling-average charts. • Export your full history as CSV or JSON. COMPETE ON GAME CENTER • Leaderboards for best single, ao5, ao12, fewest moves, the fastest marathon, and Blind with no peeks or 1 peek, in color or mono. • Twenty achievements, from your first solve to a no-peek Blind solve and a sub-100-second marathon.
