Always a good reason to come back
A game takes two minutes. Your streak, your quests and the daily challenge do the rest.
Your streak and quests
Three quests a day, a chest of coins to open, and a streak of days to keep going.
The daily challenge
A Speedrun and a Marathon, the same grids for everyone, a single ranked attempt.
Over 200 achievements
Records for every game and level, from Easy to Master, and a few hidden achievements for the most dedicated.
Stuck? Filou teaches you the technique, not just the answer.
The first time you open a game, he shows you the rule in one picture. During the game, every hint explains the reasoning so you can do it on your own next time.
In this box, the 7 has only one spot: the other cells already see a 7 in their row or column.
Challenge your friends on the same grids
Add them with their friend code. Send them a Speedrun or a Marathon: everyone plays it once, and you see who wins. Every record also moves you up the leaderboard, among friends or worldwide.
Invite a friend: 200 coins for you and 100 for them, after their first 3 days of play.
