One run, five worlds
After every eight sums Max runs straight into the next world, and each one brings trickier obstacles.
Forest
Every run starts on a sandy path between wooden fences. Jump the fallen logs and steer round the giant mushrooms.
Suburban
Front gardens and quiet streets, with road barriers, dumpsters and parked delivery vans in the way.
Stadium
Hurdles on a red running track. The crowd does the wave and jumps up after every right answer.
City
Shops, flats and skyscrapers, zebra crossings and traffic lights. The obstacles come faster here.
Space
A rainbow road among the planets, with laser fences and asteroids. Space never ends: how far can you go?
