Brain Challenge

The game is structured like Big Brain Academy in that puzzles are divided into four separate categories: Logic, Math, Visual, and Focus; the Xbox Live Arcade version, PlayStation 3, PSP, Wii, Nintendo DS, and PC add a fifth category, Memory. The puzzles can be played at three difficulty levels and more complex puzzles are unlocked through a player's progression through the game.

Many of the puzzles are similar to those from both Big Brain Academy and Brain Age. For example, Balance shows different objects on scales, and the player must determine from the relationships on the scales which is the heaviest object. e. ).

The mobile phone and iPod versions were very well received, including an 8.3/10 from IGN for the wireless version, which praised "[the] majority of the puzzles are good and the production values are strong". Pocket Gamer raved about the iPod version in its 8 of 10 review: "It's almost a no-brainer to recommend Brain Challenge. It's enjoyable, invigorating and there's a remarkable amount [of gameplay] in it".

IGN's review for the Nintendo DS version was less enthusiastic, but still singled out the Stress Test as an innovative twist to the brain exercise game formula, as was its review of the Xbox Live Arcade version, though it did mention that "there's quite a bit of depth to Brain Challenge... Making your way through Brain Challenge could take a very, very long time". DS Fanboy's review was more generous with an 8/10 review, and while calling it "an odd little game", it praised "lots of replay value, interesting unlockables, and loads of content make up for the title's flaws".
