This was bought for my very scientifically minded brother who likes to play games with the family and win... even if he does make up his own rules! This game appears to be very simple when you get it out of the box, comprising of only a canvas mat and a load of magnets. When it comes down to gameplay however, that is a different story! After reading the instructions about 4 times over each we decided we would start playing and tackle each problem as it arose. The game is a really good idea, and can be very tricky when you lay down magnets, however we found a few glitches in the rules when two things happened simultaneously, we couldnt decide which player had to pick up magnets and add them to the stack! Very entertaining to watch... but it did create arguments when people jog the table (or cats jump on it) and knock over magnets etc! Overall i thought it was a fun game, if there was a few confusing parts!
