The last is akin to getting your legs waxed. Soothing music and colours take the edge off the pain, but you're still gritting your teeth in helpless despair through most of it. Once your goal is achieved, there'll STILL be a few irritating stragglers, but the overall result is one of beauty, so you'll go back for more, like a sucker. At least you don't have to pay money to play Boomshine though!
Fun for a couple of plays, but could use more questions and better difficulty scaling. The points below about the American cultural bias are well made, too. Nice graphics though.
This is exactly what I was looking for - need to improve my mental maths for psychometric testing. I used to be good at it in school, many moons ago, but... wow, I really suck now! Practice, practice, practice!
