Problem fixed -- now it's really quite nice

Daveed V.

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.

Works well, purchased on sale for $.99 - Sept 29, 2007


I reviewed all the Sudoku apps in the store before buying this one. I'm not a Sudoku expert, so the game is challenging enough to kill 20 minutes. It works well and I haven't had any crashes. I think the initial state of the game should include the full 1-9 "pencil marks" for empty cells. For me, determining which numbers are not appropriate for a cell is part of the game play. The "auto-fill' button seems like cheating (it tells you which numbers are possible for each cell). Once it's turned on, turning it off takes away all the "penciled in numbers", even the user-entered ones. During auto-fill use, user changes to the worksheet ("pencil") numbers are over written and not kept. Otherwise, a good app.

New Version just came out!


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
