Sudoku Royale: Number Puzzle

The classic sudoku you know, without the ads, the pop-ups, or the clutter.

One clean board, light and dark themes, and puzzles from Easy to Expert. Thousands of cells get solved here every day. Pull up a board and add yours.

NO ADS, NO INTERRUPTIONS No ads. No pop-ups. Nothing between you and the next puzzle. Take notes to track possibilities, tap for a hint when you're stuck, and turn on auto-check to catch mistakes as you go. Or switch it all off and solve it clean. Every puzzle has exactly one solution, so it always comes down to logic. Play in a crisp light theme or an easy-on-the-eyes dark one.

YOUR DAILY WIND-DOWN Make sudoku your daily ritual. A fresh Daily Challenge every day gives you a few quiet minutes to switch off, clear your head, and unwind. A morning-coffee companion, or the last calm thing before bed. Then see how your time stacks up against friends and the world.

PRACTICE WITHOUT PRESSURE Unlimited puzzles at every difficulty. No timer, no stakes. Try new strategies and sharpen your technique at your own pace.

TRAIN YOUR BRAIN Sudoku Royale reads your play and calculates your Brain Age, then maps your strengths across Speed, Accuracy, Vision, Poise and Repertoire, so you can watch your mind get sharper, day by day.

MASTER EVERY TECHNIQUE The Dojo turns tricky patterns into muscle memory: timed drills for Naked Singles, Hidden Singles, Pointing Pairs and more, each with its own leaderboard, fully playable offline.

A LEAGUE WITH YOUR FRIENDS Every cell you solve feeds the weekly Belt League. Climb from White Belt all the way to Black, hold your rank above the cut, and see how you stack up against the people you know. Collect cells, promote each week, keep the rivalry going.

AND WHEN YOU WANT MORE, IT'S RIGHT THERE You never have to touch it. But the day you want a rush, drop into a live match on one shared grid. Everyone races the same puzzle, no turns, no waiting, sharpest solver wins: • Battle Royale (2 to 18 players): one grid, everyone at once, most cells claimed wins. • Tournament: a shrinking bracket. Survive each round as the field is cut, until one solver is left standing. • Duel (1v1): one grid, one opponent, one winner. Challenge a friend or get matched at your level. Every competitive match updates your Elo rating and moves you up the global leaderboard.

TRACK YOUR PROGRESS Games played, win rate, accuracy, best score, current streak. Your profile keeps score of it all, solo or competitive.

Calm when you want calm. Competitive when you want a rush. One clean, ad-free app, in light or dark.
