A sheet seems so much more frugal but how would you get it to stay on? To keep a fitted sheet from slipping off, you could try attaching it to the bed with velcro, sew something around the elastic band that tightens up and holds it on, or straight up glue it to the mattress.
The spots could then be sewn on or drawn on the sheet before attaching. We also think painting them on with Plastic-Dip would be a great way to get some traction so no one breaks an ankle in the process of playing. It will make each spot rubber!
One king size mattress should be enough for small children to play on and if you're feeling less than creative, you could technically hot glue the entire game mat right to the mattress for a twist on the old classic!
