Puzzle IO also features :
=> A smart point system ! Each complete and valid row gives you 11 points and you get to multiply that by 20 or more ! But be careful, the multiplier will decrease over time !
=> With Game Center implemented, you can now rank and compare Puzzle IO scores against your friends and challenge them to beat your highest score !
=> Six levels of difficulty which will test your wits in more than one way !
You gain access to medium, hard, expert and nightmare levels by defeating the previous difficulty level. All levels are generated on the spot, you won't face the same grid twice !
