Problem fixed -- now it's really quite nice – Satori Sudoku Review

Version 1.1 appears to address the problem with puzzles not having a unique solution, which now makes the game very usable. Things I like: - Clear and clean board with very readable digits (the subtle white/gray shading is a nice touch). - Very straightforward interface: single tap a digit to add/remove a "pencil mark:, double-tap to put/remove in the actual value. The "keypad" is always in the same position and doesn't cover the board. So far, the most fluid approach I've seen to Sudoku input. - Explicit "check this solution" button (I prefer that over the game automatically checking when I enter my last digit, in case I mistype). Things I miss: - A timer. Notable features: - "Auto" mode disables keypad buttons when first-order analysis makes a value invalid. - "Highlight": For a given digit, show all locations that could allow that digit after first-order analysis. All-in-all quite a nice implementation for $1.99. I think it deserves four stars. With an added timer and perhaps a little polish on the non-board part of the interface, I could give it five stars.
