The Japanese love their abacuses. Japanese children are taught from a very young age how to be abacus pros. Soroban DS (soroban=abacus in Jap lingo), is the first ever full length game focused around the love of the abacus.
Soroban DS will allow gamers to practice their mad abacus skillz while chilling around with their DS. The only catch? Users will be using a touch pen instead of their fingers. But maybe it’s kind of like the difference between a QWERTY keyboard and texting numerically? — Andrew Dobrow
