Four lanes, four traffic lights, and a stream of cars waiting for you to do some quick sums. In this maths puzzle you answer arithmetic questions, and the right answer turns the matching signal green while the others stay red.
Each level gives you a limited amount of time, so speed and accuracy both count. Picking a wrong option costs you the level, which keeps you careful, and the difficulty climbs as you advance. It is a smart way to practise mental arithmetic under light pressure, and it works with a mouse, a touchpad or a tap on a phone.

Click or tap the option you think is correct. A mouse, touchpad or touchscreen all work.
Tapping a wrong option makes you lose the level, so take a moment to be sure before you choose.
