You can play many games with rocks in real life.

For example, consider the following game that one might be able to play with rocks, which might increase the worth of rocks in ways both perceived and real:

When individuals get a package of collectible rocks, they should make it their duty to continue the strength and robusness of the rock as a species. To this end, they should hold rock duels. Taking two rocks between their thumbs and forefingers, they should apply pressure, squeezing them together until one of them cracks and splinters. That is the "loser", and should be burned immediately. The winner gets to go another round.

We might find, in general, the brown and red rocks to be tougher, and the newer blue ones to be genetically inferior. We might hypothesize that the blue rocks as a race cannot survive long in the intense theater of competition that is the modern rock world. Occasionally one might get a mutation, a rock that is misshapen, or pointier, or flatter than the rest. Almost invariably this will prove to be a weakness, but on very rare occasions it might give the rock extra strength. In this way, the species might continue to adapt to its environment. When one reaches the end of the pack, they would be left with one rock, the strongest of the herd. Since it would make no sense to burn this one as well, one should pack it neatly in an envelope and send it to https://collectablerocks.com, along with a 0.001 STEEM note reading, “Please use this rock for breeding purposes.”

A week later they might write back to thank the individual, and send them a token for a free 1/2 pound bag of plain rocks. One might consider this “grant crypto.” One might set aside the weekend for a grand tournament. From a field of hundreds, we could discover the True Champion. There can be only one.
