Scratch fast
Rub each spot until it is gone; thirty of them race the clock.
The fastest back scratcher in the land

Red itchy spots appear on a back. Rub them away as fast as you can, and never touch a cross.
Rub each spot until it is gone; thirty of them race the clock.
In the Challenge every itch has its own timer, and a perfect run builds up to a ten times combo.
Touching a cross costs you time, so look before you rub.
