Sudoko! is an Android sudoku app built around one shared puzzle a day at easy, medium and hard. You solve the day's grid, keep your win streak going and compare your time with friends and a global leaderboard. A calendar archive holds the days you missed.

About Daily Sudoku Puzzle - Sudoko!

Sudoko! is a free Android sudoku app from the Spanish developer Rubén Martí López, published on Google Play as RubenM. Its centre is the daily puzzle: every day there is a new classic 9x9 sudoku at each of three difficulties, easy, medium and hard, and every player gets the same grids, so solving times can be compared.

A game follows the usual sudoku rules with a few limits. You have three hints per puzzle, and three mistakes end the game. Pencil marks let you note candidates in a cell, an undo button takes back a move, and tapping a digit highlights every cell that holds it. A Speed Run mode adds a five-minute timer for those who want to race.

Around the puzzle sits a progression layer. Each solve earns XP, and a perfect game with no mistakes and no hints earns half again. Five daily challenges (start games, win easy games, finish speed runs) refresh each day, a win streak counts the days in a row you solve at least one puzzle, with streak freezes for a missed day, and Wednesdays give double XP. A global leaderboard ranks players by level or wins, and you can add friends and share a result.

The Puzzle Archive is a monthly calendar of past days, each playable at the three difficulties, so a missed day can be caught up. The app is free with ads; a Pro subscription removes them. It suits players who want a daily sudoku habit with streaks and goals rather than a plain puzzle page.

How to play Daily Sudoku Puzzle - Sudoko!

Open Sudoko! and choose today's puzzle at easy, medium or hard.
Fill the 9x9 grid so each row, column and 3x3 box holds the digits 1 to 9 once.
Tap a cell, then a digit; switch to notes mode to pencil in candidates.
Use up to three hints if you are stuck, and avoid a third mistake, which ends the game.
Finish to earn XP and extend your streak, then compare your time on the leaderboard or open the archive to play a past day.
