If the tiles get dirty, can they be washed? If so, how?
The tiles can easily be wiped off with a damp cloth.
Can the game be played outdoors?
Absolutely – as long as it's not a very windy day.
What's the best surface for playing the game?
Hardwood floors, rugs, tile, concrete... as long as you're on a flat surface, on the ground, and you have lots of room to spread out and play, it will be great!
How far apart should the tiles be placed?
It's best to have the tiles about a foot apart from each other – so players can land on any tile, and still have plenty or room to move.
