Okay, now this one reminded me of a game I played ages ago. I think someone sold me a game at school which was a bit like Mario Party, but where the minigames were maths challenges. I think the board was an island and the premise was that you had to escape it before a volcano erupted.
...I know, pretty much irrelevant, but the point is that it reminded me of a game I haven't thought about in ages and for that reason I give it 5/5.
