Match up three numbers to combine them and fill the counter by creating
multiples of ten to complete a level. You get 1 counter and 1000 points for 10,
2 counters and 4000 points for twenty. There are six levels, and level 5 is the
lightning round.
There's a life bar at the bottom which goes down if you let a number reach the
bottom or make a combination which is higher than 10 but lower than 20. You
don't lose life if you make a combination lower than 10, and you even get a
small amount of points.
Apologies in advance to those who 'waste' a lot of time on this, not that exercising the old grey matter is ever a waste.
