SudokuSpire vs Unlike

Sudoku Spire turns the world's favourite logic puzzle into a roguelike climb. Every board is a fresh, hand-checked sudoku with exactly one solution — fill each row, column, and box, then climb the branching Spire to the next. But now a wrong number costs health, and running out ends the run. The calm of pure deduction, finally with stakes and a reason to dive back in. FAIR BY DESIGN There is no luck here. Every board is procedurally generated and verified to have a single solution, so you can always reason your way to the answer — never guess. Relics change the math in your favour; they never replace deduction with chance. RELICS THAT BEND THE RULES Clear boards to claim relics and stack a build that's yours alone: - Lantern reveals correct cells at the start of every board - Surveyor's Glass hands you a full solved box - Aegis Charm forgives your first mistake - Jeweler's Loupe auto-fills your candidate notes - Second Wind pulls you back from a lethal slip, once per run No two ascents play the same. CLIMB, FALL, CLIMB AGAIN Boards grow from a gentle 4×4 up to full 9×9, and Wardens at each milestone fight fair but hard — deducing from fewer clues, on bigger grids, or with your notes disabled. Every board you clear banks Shards, even on a failed run, to spend on permanent upgrades: more health, a starting relic, richer rewards. You always climb back stronger. SUDOKU SPIRE PRO (one-time purchase) - Removes all ads - +1 maximum health every run - A free Heartstone relic at the start of every run - +25% Shards from every board Free players can unlock all Pro perks for 30 minutes by watching a short video — and revive once per run the same way. Sudoku Spire shows non-personalized ads only and does not track you across other apps. If you love sudoku but always wished a single solved board led somewhere — this is your climb. Read the grid. Reach the summit.

Only shared edges count: above, below, left and right. Gold-dot cells are already fixed; every other cell needs a style.
