FOURSTRA is a mathematical game that uses a repeating four-part pattern made up by combinations of the four foundational arithmetic operations (though not necessarily inclusive of all). Figure out the pattern by finding the next four numbers and then fill in as many boxes as you can to set your score. But hurry, once you’ve solved the pattern, the fuse is lit! Each correct answer buys you time, but less the further you go! Also, be careful with your answers, four wrong and you're out!

Come back for a new pattern every day and a chance to set the high score!
