Select high numbers and low numbers one by one until you have six, then, before the countdown ends, try to reach a target number by adding, subtracting, multiplying or dividing these numbers. Play against others or just practise.
The target number can be random, or can have a known solution. Either way, you can ask to see the solution generated by the system (or the nearest that can be found).
