Of course, we should keep in mind that they sell their own sudoku, including one of your competitors. Nikoli argues that this changes (they would say improves) the gameplay, and I don’t disagree with them. How come you like this so much? Are there any advantages to solving such a puzzle? Or is it just a matter of taste? I’ll see I’ll add it as an option in an update. July 13th, 2008 at concept of rotational symetry is interesting. More importantly, ACTSudoku does not generate rotationally-symmetric puzzles. That said, I’m willing to give it a shot the way it is. I suggest swapping number-placement and pencilmarks, so that changing the number color is what takes the longer tap. Pierre: I did like ACTSudoku‘s input method (which I thought similar to the ring of numbers) based on the screenshot, but I’m more dubious after watching the screencast. Those are the black cells in the diagram. Yes, rotational symmetry applies to the given numbers. It’s also one of the few that generates rotationally-symmetric puzzles. The dragging idea is intriguing, and though a row of numbers is non-obvious no matter what you do with them, at least the product page tells you up front. Simple, usable interface: Matter of taste. OPTIONALLY, ACTSudoku may help you by automatically blocking excluded values. The ability to set pencilmarks: CHECK: ACTSudoku calls them markers. Obvious input method: Watch the screencast at I think you’ll like itĤ. They are symetrical along one axis: horizontal, vertical or diagonalģ. A sudoku generator: CHECK: virtually unlimited fresh games, not plain transformations applied to existing boardsĢ. I am the author of Houdah Software’s ACTSudoku for iPhone. Is that on initial placement of the “given” numbers? I also don’t quite understand the 180 degree thing. It’s small at 6.6 MB ( I bought and downloaded it over EDGE ) and keeps statistics (i.e. The only thing I think might annoy you is needing to tap the space to enter the number. I haven’t played any of these (the one I linked has 5 stars just 3 reviews), not much of a Sudoku player, just interested in UI design and convention on this new platform. Advanced Tile Sudoku does that, is only 1.5 MB, and is more visually appealing to me than the others you listed. What if the tiles are at the bottom and you drag them? That avoids the prefix/postfix problem and seems far more iPhone-appropriate / non-modal than prefix, postfix, or handwriting. I don’t mind that for a great app, but 100 MB is pushing it. 17 Responses to “Requirements for a proper iPhone sudoku app”īig Bang Sudoku doesn’t look too heavy to me: the Platinum Sudoku you also listed is 52 MB, though, nearly 19 times bigger! Still, just the size of an album. If your sudoku game is in CGA, then I don’t want to look at it, which means I don’t want to play it, which means I don’t want to buy it.Ĭategories: Gaming iPhone iTunes/iPod. I only have 16 GB of flash memory-don’t waste it! No excessive artwork like Big Bang Sudoku has. The ability to set pencilmarks, to keep track of what numbers are viable for a cell (helping to avoid wrong numbers, especially at higher difficulty levels). Platinum Sudoku is clearly postfix, because its input method is a ring of numbers around whatever cell you tap on. I could get used to either way, but a good interface doesn’t make me guess.Īmbrosia’s Mr. A row of numbers at the bottom doesn’t work because I can’t tell whether the game is prefix (tap number first, then cell) or postfix (tap cell first, then number). (In particular, all the Will Shortz puzzles are like this.) Many sudoku generators actually generate Number Place puzzles, which don’t have this constraint. The difference is that a sudoku puzzle is rotationally symmetric: if you turn the puzzle 180°, it still looks the same.

Proper sudoku puzzles, not Number Place puzzles. Give me all the sudoku the iPhone OS’ PRNG can create for me. The game should not cap me at x-hundred or x-thousand puzzles.
