This simple (but noisy) game from BBC Skillswise for practising multiplication tables is always popular with students, although it is actually from a site aimed at adult learners.
I like this because it is offering practice rather than a test – the game shows you a question or an answer and you have to find it on the tables square. Matching the answer to a question is a nice way to practise multiplication tables.
It’s good fun too!
