Numslide: Slide Sudoku Puzzle

Numslide is Sudoku with a twist you've never played.

Instead of a ready-made grid, the 3x3 blocks arrive scrambled. Slide them into place, 8-puzzle style, to BUILD a valid Sudoku, then solve the numbers. Two kinds of thinking in one board: spatial and logical.

■ How it works

1. Slide the blue blocks into the empty gap to assemble the board.
2. Lock it, and the empty block opens up. Now solve it like classic Sudoku.
3. Stuck? Unlock and rearrange. Your entries and notes move with the blocks.

■ Two modes

• Slide Sudoku: the signature build-then-solve puzzle, across a ladder of tiers.
• Classic Sudoku: a full, clean Sudoku with 4 difficulties x 30 levels if you just want the pure game.

■ From gentle to brutal Climb from Beginner to Legend, then unlock the hidden Trials of Hell (Cerberus, Minotaur, Hades and Lucifer) where "traps" look consistent but can't be completed. The ultimate test for Sudoku veterans.

■ Fair leaderboards Rankings are raw completion time, with no normalized scores. A cheat-detection pass keeps boards honest, so a fast time actually means something.

■ Save Point (one-time unlock) Save before a risky guess and rewind if it goes wrong, without breaking ranking fairness. The power tool for climbing the hardest tiers.

■ Honest by design

• No subscription. A single one-time purchase unlocks unlimited hints and answers, the Save Point, and removes all ads.
• Play offline. No account required.

Slide, build, solve. Welcome to Numslide.
