There are lots of sudoku games for the iPhone, but Astraware is one the few developers that's picked up an award for its number crunching puzzler.
Its popular nine-figured brain-teaser has now made it to the iPhone, and features a host of unique traits to help ease gamers into the mathematical number arranging classic.
AstrawareSudokuboasts a wide range of assistance functions including smart hints, pencil marks and 'hold-and-highlight' to help beginners. There's also a daily download to keep the gameplay fresh, a puzzle generator and a companion website featuring solving techniques.
If number arranging is your thing, it's probably worth swinging by the App Store before October is out, since Astraware is introducing the game at a special offer price of £1.19 until the end of the month (click 'Buy It! below).
If you're looking for a bit more reassurance before shelling out, here's a gameplay video, and don't forget to hit 'Track It!' for more coverage as it comes in.
