As we figured last week, Numblast will be blastin’ up the US store this week. (I couldn’t resist that one)
Sony has this to say:
Get your hands on this addictive puzzle game (available for both PS3 and PSP) at the attractive price of $4.99 for either platform. Based on simple number combinations, Numblast is colorful, quirky, fast-paced and easy to pick up, but only those with quick wits and mental agility will make it to the top of the online rankings.
For $4.99 I guess I will pick this one up to review this week!
F5ing the PSN Store like a madman.

I played the Japanese demo a while back so I’ll definitely be picking this up.
