The Heist, a puzzle game from the team behindMacHeistthatwe covered recently, has beatenAngry Birdsout of the US App Store’s Top Paid App spot in just half a day, bringing a record 275 day run for Rovio’s runaway app to an end.

According toThe Loop, The Heist’s developers report 25,233 sales of the app in half a day, which was enough to beat Angry Birds — at least for now. It remains to be seen whether The Heist will see the sustained sales that have kept Angry Birds high in the charts for so long: the competition for a customized iPad 2 couldn’t have hurt initial traction. Both apps compete at the $0.99 price point, leaving only gameplay and smart marketing to differentiate them.

The Heist was developed byMacHeistandtap tap tap. MacHeist is famous for putting together Mac app bundles that are sold at significant discounts, and tap tap tap, an iOS development shop, share quite a bit of their management and development staff.

Angry Birds’ market saturation works in The Heist’s favor (do you know any iPhone users without a copy? I don’t!). Angry Birds has been around for long enough that the majority of iOS gamers have the app already, reducing the pool of buyers for Angry Birds with a market ready and waiting for fresh blood and new challenges.

The Heist has also taken the top spot in the UK, where Angry Birds is only the fifth most popular paid app. And in Australia, both games appear on the chart but it’s Little Wings sitting at #1.

It’ll be interesting to see how sales of The Heist are looking in a few days, and whatRoviois preparing to do in response to this threat against its chart dominance.
