I have two kids aged 6 and 7, they are just starting to learn about multiplication and they love this game. The multiplications are quite easy.... mainly 2, 3, 5, and 10 times tables with a few easy 4 and 6 ones thrown in. I think it is good for younger kids but may be a bit easy for kids who already know their tables quite well.
It is very useful for teaching about how different multiplications can add to the same total.... eg 3*10 = 6*5 or that 3*4 = 4*3.
It is a good fun game and I would recommend it.
