The conceptually brilliant and rambunctiously cheerful "Quarrel" is what happens when Boggle and RISK join forces. Up to four armies share adjacent territories with one another, and dominating a "Quarrel" match comes down to wiping out opposing armies before they decimate yours.
This time, though, a battle comes down to eight random letters and one chance to build a better word than your enemy. The more troops you have occupying the conflicted square, the more letters you can use to build your word, and the winning army can (depending on circumstance) take the square completely, whittle it down to one opposing troop, or turn enemies into turncoats. "Quarrel's" cheerful presentation is dangerously caffeinated, but the actual game takes a great idea and gets it absolutely right.
All of this was already the case with "Quarrel's" iOS iteration, which included lots of well-tuned single-player content (campaign, customizable match play, daily challenges) but no multiplayer of any kind. With the move to Xbox Live, "Quarrel" finally fixes that: There's no local multiplayer (which makes sense given the game's setup), but you can play online with up to three others. This, along with all the iOS version's single-player content and some new scenario wrinkles for those playing alone, makes this the best version available (and makes the exclusion of multiplayer on iOS even more annoying than it already was).
The only downside: Playing "Quarrel" with a controller isn't as graceful as it is on a touch screen. Fortunately, it's a slight rather than significant inconvenience, and if you have a Chat Pad, you'll be happy to know it's supported.
