Tomorrow sees the launch of Dual Brain Vol.1: Calculation, a brain training game not unlike Nintendo's very own franchise known as Dr Kawashima’s Brain Training in Europe (Brain Age in North America).

Of course, we're being treated to a brand new Brain Training game from Nintendo in the new year, but Japanese publisher D-O is getting in just ahead of that title and just in time for Christmas, too. You can check out some of the gameplay in the trailer above - even if some of the translated English subtitles are a little poorly worded.

The game has you solving problems within a time limit, aiming for a highscore that can be compared to other players from all around the world. There's a focus on calculations in this title, as you'd expect, and everything revolves around a 'Dual Task' mechanic whereby pulling off said Dual Task will earn you more time.

So why consider this over Nintendo's own offering? Well, it's a considerably cheaper way of getting your brain training fix. Nintendo's game - which you'd expect to be more polished and potentially full of more features - costs £29.99 in stores (or £24.29 if you want it digitally without a stylus); Dual Brain Vol.1: Calculation launches tomorrow for just £11.99.

What do you think? Worth considering, or will you be waiting for Nintendo's own Dr Kawashima’s Brain Training to launch in January? Tell us below.
