Hello,
3Doku for iPhone 1.3 has just been released on the App Store at http://itunes.apple.com/us/app/3doku-for-iphone/id452799900?mt=8
3Doku is a refreshing twist for die-hard Sudoku players: the goal is to complete a 3D cube obeying to Sudoku rules. It's quite a bigger challenge compared to normal Sudoku, especially when playing at the most difficult levels.
