This is a wonderful maths puzzle site where players must use + - x or ÷ with a set of four numbers to equal 24. There are many modes to choose from, including an easier 'kids' version of the game, timed games and even a battle mode where you can challenge other people.

I hoped if I just waited a day the site would be back up. I really am interested in good math interactives. I am hopeful the site will be restored or redirected.
A great general maths site with lots of tutorials, activities and games which will help your students at school and at home.
