A while back I was wondering when we would see multiplayer Sudoku since it would be fun to play against a friend or someone over the Web. Well, the time for wondering is over: Introducing Sudoku Combat.
Created by Marc Belmont, this browser-based multiplayer version of the popular puzzle game offers a new experience for those that prefer a more competitive challenge. Just enter a user name, select a puzzle difficulty, and then choose to play against a friend or a random stranger. Then it's a race to the finish.
Once a game begins, your opponent's progress is shown in a grid to the right of your own, which adds a little pressure to the mix. A chat window allows for teasing and taunting or friendly chat during play.
Friendly play: To play against a friend, have one person initiate a game by clicking the "Play against a friend" button. Doing so will display a URL link to copy and send to your friend via email or instant messenger.
Avatars: You may also choose an avatar to use for the games you play from a list of hundreds. There is no account to create or registration with the site, your avatar choice and number of games won and lost are conveniently saved as cookies on your computer.
Settings: During play you may select to have cells display multiple numbers if you are like me and need to make little notes while you solve a puzzle. You may also turn on/off the use of colored numbers, as well as the display of the timer. An additional feature called "sticky keys" will insert the last number you typed into a cell just by clicking it.
Sudoku Combat is an excellent multiplayer implementation of a very addictive puzzle game. Oh, and there is a single player version in case you need some practice. Click.
