Quarrel Deluxe, the very fun iOS board/word game that mixes elements from Risk, Scrabble, and Countdown, is on sale at the App Store right now for just $.99, a fifth of its usual $4.99 price. New iPhone owners coming in with the 4S's launch, don't miss out on this!

The deal will last until this Sunday, 11:59 PDT, when it will jump back up to $4.99. Don't forget that you can still get standard Quarrel, the trial version of the game, for free. And if you don't have an iOS device, Denki still intends to release this as a downloadable game for consoles.
