Xbox Live Arcade will see Brain Challenge and Bliss Island as its newest releases this week.
The first title, produced by Gameloft, is akin to Nintendo's well-known Brain Age offering. Online and offline multiplayer supports up to four players. Game modes include stress, creative and child tests. The price is 800 Microsoft Points.
Coming at half the price will be PomPom's offering, Bliss Island, which features a fantasy creature vying for the island's top prize. The colorful game offers 25 challenges across nine levels.
