Store description excerpt
You don't get a harder board here until you've earned it. Sudoku Daily is a clean 9x9 sudoku game built on that one idea. Five Levels, and You Unlock Every One Everyone starts on Easy. Solve two Easy boards and Normal opens. Four Normal solves open Hard, six Hard solves open Expert, and eight Expert solves open Master. Levels are unlocked by solving, never by paying, so the grid in front of you is always one you've already proved you can handle. Easy — 37 to 41 given numbers Normal — 30 to 36 Hard — 23 to 29 Expert — 18 to 22 Master — 17 Master: 17 Clues, 64 Blanks Easy hands you 37 to 41 numbers. Master hands you 17 — fewer than half, and fewer than any other level in the game. Almost the whole grid is yours to build, one cell at a time, and it only opens after eight Expert wins. Every number you enter is checked against the solution the board was generated from. Puzzles That Don't Run Out There's no fixed pack here. Every board is generated on your device the second you press start, so there's no puzzle count to exhaust and nothing to wait on. Tools for Thinking, Not for Cheating Pencil notes — jot every candidate into a cell, just like scribbling in the margin of a newspaper puzzle Undo — walk back through your moves when a line of reasoning falls apart Hints — three in a standard game, for when a grid stops making sense Mistakes — a five-strike counter, plus up to two extra chances when a board gets away from you Highlighting — light up the row, column, and box you're working in, or switch it off Timer — so improvement is a number and not a feeling Extreme Mode, When Five Levels Aren't Enough Solve four Hard boards and Extreme unlocks. One hint instead of three, three mistakes instead of five, no extra chances, and no notes or highlighting at all. It scores double and keeps its own stats. Built for the Gaps in Your Day Boards are generated and played entirely on your phone, so a tunnel, a flight, or a dead zone makes no difference. Pause halfway through, come back tomorrow, and your grid and your notes are exactly where you left them. The only thing that needs a connection is the global leaderboard, where each win scores points from your time, mistakes and level. How It Works Fill every row, every column, and every 3x3 box with the numbers 1 through 9, each used once. That's the whole rule. There's no arithmetic anywhere in sudoku, only deduction, which is why it stays interesting for years and works just as well at eight as at eighty. Sudoku Daily is free to download and supported by ads. Want more hints, or another chance after your mistakes run out? You can earn them by watching a short video. Two Easy boards are all that stands between you and Normal. See how far up the ladder you get. Questions, bugs, or something you wish the app did? Tell us. We read every message.
