Math practice game that isn't terrible

I am helping my niece through sixth grade math online and she struggles with some basic things like multiplication of integers. Is there an arithmetic practice video game that is even halfway decent? My search has turned up nothing that didn't seem incredibly cheesy and unfun. I would pay!

Thank you so much.
