On August 1, 2008, iLounge published iPhone Gems: Every Sudoku Game, Reviewed, a feature article looking at 23 different Sudoku releases for the iPhone OS. This review focuses on Sudoku Vol. 1 ($6) by Japan’s Hudson Soft; you can read the full article, with screenshots of all of the games together, through the link above. A collective screenshot below shows you some of the other Sudoku interfaces you can expect to find in these titles.
If you’re reading this article, you probably already know that Sudoku is a one-screen puzzle game based upon a 9-by-9 grid that’s partially filled with numbers. The objective is to fill the empty spaces of the grid with single digit numbers so that the same digit does not appear twice on any horizontal or vertical line.
Additionally, the same number should not appear twice in any of nine 3-by-3 mini grids on the screen.
iLounge’s top-ranked Sudoku games are ones that offered fully-functional renditions of the game, with impressive interfaces, bonus features, user customization, and pricing as of the time we tested them. The fewer of these features a given game had, the lower it rated. While updates to these games may well be released over time, and their features may change, we couldn’t wait around forever for bad or so-so titles to catch up with ones that were already good or great.
One of the standout versions we tested is the professionally-developed Sudoku Vol.
1. In addition to six plain wallpapers and six fonts—notably including a Japanese font so that players can experience the game in its fully original form—the game has its own simple music and sound effects, pre-empting your iPod’s, and the ability to make guess marks on the board. Hint, undo, and redo features are included, as is an interactive tutorial. The game features 15 stages, five initially locked, with 50 puzzles a piece. It was co-developed with Nikoli, the “originator” of Sudoku.
