If you’re a Mac user, there’s a decent chance you’ve heard of Macheist, a deal site that bundles different Mac applications together for a ridiculously low price. While The Heist isn’t a bundled software deal, it’s an insanely addictive puzzle game for the iPhone based on a theme of trying to crack into a safe — hence the title. There are four different puzzle types and over 60 levels, each one with distinct themes and objectives. And, in addition, there’s a promised prize to any user that completes every level in the game. Not a bad hook, right? The game is built by developer TapTapTap, makers of the Camera+ iPhone app, and it’s available now for $0.99 in the App Store — and it’s currently sitting pretty as the No. 1 paid app.
