Yushino

Yushino offers a social crossword game using numbers for iOS devices.

Yushino is a social 'crossword' game with numbers, best described as the Words with Friends of numbers. The gameplay and user experience is similar to Words with Friends and Scrabble, except numbers replace letters. The lack of a dictionary allows non-native english speakers to play as well. Although the game is not a derivative of Sudoku, it is a multi-player number-based game, so several Sudoku players have started playing it, judging from the reviews on the iTunes store. Yushino is currently available on iOS and it has just started accepting testers for its Android and Facebook Apps which will be released in February and March of 2013.
