This is a great free maths game for kids that allows the child to practice their adding, subtraction, multiplication and division.
The questions are multiple choice and the are a varying number of possible answers depending upon the level; easy - 3, medium - 4 and difficult - 5.
Points are awarded based on whether you get the answer correct first time, or have several attempts. There is an encouraging voice which tells you if you get an answer right or wrong, prompting you to try again. It's a very useful app if you are a parent who wants to help you child improve their maths skills. I would rate this 9 out of 10.
