Store description excerpt
Blue Sudoku is a quiet place to solve puzzles. No account, no sign-up, no daily streak nagging you to come back. Open it, pick a difficulty, and play. Your progress is saved automatically, so you can put it down mid-puzzle and pick it up days later exactly where you left it. FIVE DIFFICULTIES, EARNED IN ORDER Easy and Medium are open from the start. Win eight games on Medium and Hard unlocks, then Expert, then Chaos. Each level is a real step up, and reaching the next one means something because you got there by playing. BUILT FOR LONG SESSIONS • Pencil marks for the possibilities you are still weighing • Highlighting for the row, column and box you are working in • Matching digits lit up across the grid • Undo, erase, and a hint when a puzzle stops moving • A timer you can hide entirely if it stresses you out FIVE THEMES Light, Classic black and white, Dark, and two pastels — Lavender and Peach. Correct and incorrect entries stay clearly distinguishable in every one of them, which is not a given and took some care to get right. DUEL A RIVAL Race a stand-in opponent whose pace is built from your own past times. A lane above the grid shows both of you moving; finish first and the win counts. There is no server, no matchmaking and no chat — the rival is generated on your device. CLIMB THE FOUR ELEMENTS Fire, Water, Earth and Air, twenty stages each. Wins move you up the ladder one stage at a time, and the difficulty follows your rank rather than a menu choice. COLLECT THIRTY-TWO BADGES Every second finished game lights another badge. Eight badges seal an element; four seals complete the set. Finishing counts, not winning. TRACK YOUR PROGRESS Per difficulty: games played and won, win rate, flawless wins, best and average time, current and best streak. All of it stays on your device. ELEVEN LANGUAGES English, Turkish, German, French, Spanish, Italian, Brazilian Portuguese, Japanese, Arabic, Urdu and Persian. EVERY PUZZLE IS SOLVABLE BY LOGIC Puzzles are generated with a single guaranteed solution and graded by the techniques they actually require. You will never need to guess. PLAYS OFFLINE The puzzles are generated on your device, so the game works on a plane, on the underground, or anywhere with no signal. Only the ads need a connection. A NOTE ON ADS The game is supported by ads: a banner while you play, and an occasional full-screen ad between games. Video ads are always optional — you watch one only if you choose to trade it for extra hints, and declining costs you nothing but the hint.
