Sudoku Zenith

Sudoku Zenith is a calm, clean Sudoku game that works fully offline. Every puzzle has exactly one solution, and the hints teach you the real solving techniques instead of just filling in numbers. CLASSIC SUDOKU, SIX DIFFICULTIES Work through numbered 9×9 levels from Easy, Medium and Hard up to Expert, Master and Extreme. Pick up where you left off, or browse the levels and replay any puzzle to beat your best time. A NEW DAILY PUZZLE One Daily Sudoku for every date, the same for everyone and made right on your device. Missed a day? Catch up on the last seven any time. LEARN THE TECHNIQUES Practice mode gives you a puzzle that needs the technique you choose, with free hints and nothing at stake. A built-in reference explains each method, from singles and pairs to X-Wing, Swordfish and chains. HINTS THAT EXPLAIN Stuck? A hint first points to the right cell, then a candidate, then explains the move, and only then reveals the number. Every game comes with free hints. CHALLENGE AND OTHER GRIDS Challenge mode: no hints, three mistakes and it is over, and a 1.5× score for the brave. Fancy a change? Play the same rules on quick 6×6 grids or roomy 12×12 grids. MORE WAYS TO PLAY Time Attack: solve as many quick puzzles as you can before the clock runs out. Endless: puzzle after puzzle on one run, a little harder each time. Missions pay coins and gems for your goals, and the shop has hints, board colours and a free chest.
