I like this idea, but these solutions do not match what actual dominoes look like.

Hi Janet. I guess their are bigger sets of dominoes than we realized. I thought you were right but wanted to verify and I found this: https://www.amazon.com/Double-Color-Dot-Dominoes-Game/dp/B001D4MIZM/. So apparently these are possible answers.
