Invisible Box Challenge

Đặt mình vào thử thách và bước qua một số hộp mà không phải là ngay cả ở đó.

The all original - Invisible Box Challenge!

Are you tired of stepping over your neighbour's dusty old box? Well you're in luck, because you've got all real invisible boxes right at the tip of your... finger tips.

Wider than you can ever imagine and taller than you're tallest dreams - put yourself to the challenge and step over some boxes that aren't even really there.

Play against your friends, family, co-workers, and the world wide leaderboards.
