All-TimeThe daily master sudoku sits between Expert and Evil — 18 to 19 given digits, requiring forcing chains, coloring, and the deepest end of pure logic. A fresh puzzle every visit means the daily master never repeats its tricks. Most master-tier solves take 40 minutes to an hour, occasionally longer; this is the tier where pencil marks aren't optional and chains of inference span multiple cells. Master puzzles are deliberately constructed so every step has a logical justification, but finding the right starting move can take real searching. Solve a master daily and you've genuinely earned bragging rights. Create a free account to save your master solve times and see how you rank on the all-time leaderboard.
