Satori Sudoku 4+

Love the new version, puzzles are much better.. looks pretty

and looks like they made the markers a bit bigger.

good to see the dev is listeneing to comments.

pity all those comments for the 'old' version are still in the store.. they dont really apply anymore.

I love that the keypad doesnt cover the board like on some of the other games (how the heck are you supposed to see the board if the keypad is touching it?? those versions are lame)

this is very well thought out.

To darkest - game difficulty def gets harder when you change it in options. Did you actualy play the game? LOL

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.

In order for a $1.99 app to compete with the free ones out there doing the same thing, it needs to have a little more robust functionality, and this one doesn't quite deliver. For starters, the difficulty ratings are inconsistent and indistinguishable between "normal" and "difficult", and even on the most difficult level, the puzzles are far to easy for the advanced Sudoku puzzler. Users serious enough to pay expect a higher degree of difficulty and to leave the free apps to the ameteurs. This app could also benefit from some simple scoring/timekeeping elements for the competitive player to track their personal bests. An undo button would be nicer than the cheater elements, so you can backtrack to before your mistake was made instead of just cheating to see the answer. Finally, something at the end of a successfully completed puzzle would be nice rather than the bland statement "congratulations, you solved the puzzle." The overall UI is good so I think this one has promise but needs some work on the features.
