A brand new, fun and addictive puzzle game for those that love to stretch their mind and give their brain some exercise! Sudo Crabs is guaranteed to challenge your reasoning skills and improve your strategic thinking and concentration.

The goal of the game is simple, make unique rows, columns and blocks. Unique means using all numbers from 1 to 9 in any order without repeating any digits.

If you complete a unique row you get a row star, if you complete a block you get a block star and if you complete a unique column, yes you’ve guessed it, you get a column star. When you’ve got all 3 stars you’re rewarded with coins!

Coins can be used to buy power-ups! These can help you out of sticky situations.

Just be careful, when collecting stars, you cannot get a row star if you already have one, when this happens your row star will disappear and you’ll get a surprise. This also goes for block and column stars.

Even though Sudo Crabs is often referred to as Arcade Sudoku, it is not sudoku! It's a unique number placement puzzle game.

Sudo Crabs Features:

With no puzzles to complete, the game lasts as long as you can keep your wits about you! How long will you last?

No two games are the same! So think, plan and enjoy, this moment will never repeat!

Your own best score is always visible so that you know how you fare. The best of the best’s score is also always visible and you are every now then updated so that you know how you rank on the leaderboard. You can also challenge your friends via Game Center.

With Game Center’s Game Save feature you can start your game on your iPhone and pick up where you left off on your iPad or vice versa.

Sudo Crabs starts easy and gets progressively harder, but not to fear you can always build chains to unblock yourself or boost your score. And if that doesn’t work out there are always power-ups you can use!
