Ok, this has to be played on a solid surface, please don't listen to what it says about you can play on grass, it cannot, my grass is very low we have someone up keep it every week, do what is needed in between. If you have luxury carpet it wont work as well. You need a flat surface like commercial carpet, stone or tile. The game was fun, we missed going to the boiling alley. I did an out door oasis for my sons birthday. We had to play on deck to make it work.
