Xbox Live Arcade shows a belligerent disregard for productivity this week, hosting a pair of light puzzle games that are sure to weigh heavily on your mind during working hours. Why not have a go (and then just one more) at Gyromancer, the gem-shifting collaboration between Square Enix and PopCap? The cost of entry is 1200 ($15). If it's a cohesive concoction of puzzles, RPG elements and item collection, your departure is likely to be at no point.
PlayFirst is also serving up an XBLA version of Diner Dash for 800 ($10). The culinary-themed time management game should be an ideal snack in between gorging on Dragon Age: Origins, Modern Warfare 2, Assassin's Creed 2, Left 4 Dead 2 and ... hmm. How good are you at time management?
