Mix Sudoku Light
Mix Sudoku Light is a multi-platform release from Conceptis just waiting to appease the sudoku monster within. The game has a number of useful features, including support for both mouse and keyboard interfaces, undo/redo buttons, the ability to check your current answers for errors, number highlighting, and a save function. It does a great job bridging the gap between pen and paper gaming and browser interfaces, all without the constant fear of paper cuts!
In addition to a very player-friendly interface, Mix Sudoku Light comes with six versions of sudoku, ranging from the very familiar to the less recognizable:
- Standard sudoku - Place the numbers one through nine on the grid in such a way that every row, column, and 3x3 box includes them only once.
- Diagonal - Like standard, but includes diagonals in the restrictions.
- Irregular - The nine-square "boxes" are now irregularly shaped.
- Odd/Even - All the numbers in shaded boxes must be one or the other.
- Chain - Like Strimko, numbers are set in crisscrossing chains.
- Multi - Grids overlap, but numbers must adhere to traditional sudoku rules.
The main downside as of now is the limited number of puzzles available: only ten of each variation for 60 total, and the same puzzles in each version. Conceptis says it will be releasing updates as the weeks go by, along with new online versions of other pen-and-paper puzzles, such as Picross, Kakuro, and Battleships. Conceptis has long been an excellent provider for these kinds of puzzles, though the registration requirement for the main site has kept a chunk of their potential audience away. I'm glad to see they're reaching out across the internet. Online sudoku games may be a dime a dozen, but they're always in demand, especially when, like Mix Sudoku Light, they're done so well.
