So you have just enough time each day to play one Str8ts and one Sudoku. It might as well be hand picked by the author and it better be the best puzzle a human can make. It also should be made by the best number puzzle guru around. Andrew Stuart is the best at creating number puzzles that unfold like a symphony of numbers instead of musical notes. Sudoku+ Str8ts is also a universal app. If you don't play the puzzle from yesterday you can play it the next day essentially giving you four puzzles a day. http://itunes.apple.com/us/app/sudoku-str8ts/id404448321?mt=8 PM me for a code.
