Following the success of Nintendo’s Brain Age, mobile publisher Digital Chocolate is releasing Brain Juice–a series of ‘casual games’ for your brain.

Juice your brain with three fun, brain-stimulating modes! Boost your brain with mind blowing Mini Games that give your brain a well-deserved workout! Timed Mini Games include Quick Math, Path Memorization, Color Counting and more! Track your daily progress and challenge up to three friends at the same time in the ultimate battle of the minds!

Some reviews suggest however, that the games may not completely reach their goal.

Not only does boredom set in after the first couple of days, the exercises come down to your dexterity with your phone’s keypad as much as they do to the power of your brain.

A practice game mode enables you to try your hand at any of the challenges you’ve unlocked so far, but with the results not counting toward your brain wattage, it adds little interest. The multiplayer mode wears thin just as quickly. There’s just no incentive to keep going.

Still, the casual game category will be one to watch–both online and on mobile in the coming years–as it often finds success with audiences who don’t enjoy the traditional ‘gamer’ style console and handheld games.
