TSR Sudoku

TSR Sudoku is a clean, classic Sudoku game for beginners and experienced solvers. Every puzzle is generated on your device with a single solution, in four difficulties: Easy, Medium, Hard and Expert. HOW TO PLAY Fill the grid so every row, column and 3×3 box contains the digits 1 to 9 exactly once. Tap a number, then tap the cells where it goes. Every cell holding that number lights up, so you can see where it already is. TOOLS • Notes: pencil in candidates. Placing a digit clears it from the notes in its row, column and box. • Undo, erase, and live conflict highlighting for duplicate digits. • 3 hints per puzzle, plus an optional rewarded ad for one more. • Pause at any time. An unfinished puzzle is saved, so you can pick it up later. SCORE AND BADGES • Score points for every solve: 5 for Easy up to 20 for Expert, minus 1 per mistake. • Each mistake also adds 10 seconds to your time. • 28 badges with Bronze, Silver and Gold tiers for streaks, speed, skill and score. • Stats for every difficulty: puzzles solved, points earned, all-time and 30-day best times. MAKE IT YOURS • 23 color themes, from light and dark to bright patterned tables. • 4 board styles: classic grid, rounded, circles and hexagons. • Left-hand layout for landscape play. • Works on phones, tablets and foldables, in portrait and landscape. GOOD TO KNOW • Puzzles play without an internet connection. • TSR Sudoku shows banner ads. A one-time purchase removes them; rewarded ads for bonus hints stay optional.
