Suji is a Sudoku app that teaches you how to solve, not just what to fill in. HINTS THAT TEACH Stuck? Ask for a hint and Suji walks you through it in three steps. First it points you to the right row, column or box. Then it names the technique and explains why it works. Only then does it show the answer. Six real techniques are covered: Naked Single, Hidden Single, Naked Pair, Hidden Pair, Pointing Pair and Box/Line Reduction. TWO BOARD SIZES Classic 9×9 in Easy, Medium, Hard and Expert. Mini 6×6 in Easy, Medium and Hard for a quick break. MADE FOR FOCUS Clean grid, peer highlighting, pencil notes, undo and redo, and error checking you can set to instant, on demand, or off. TRACK YOUR PROGRESS Win rate, best times, streaks and games played for every size and difficulty. PLAYS OFFLINE Every puzzle is generated on your device. No account, no internet needed. OPTIONAL ONE-TIME PURCHASES Suji is free with ads. Remove Ads is a one-time purchase, and the Theme Bundle unlocks 9 more color themes. No subscriptions.
