We should all come up with our own coin, Pincoin. Built into the latest pins each new high score generates a QR code that when scanned grants 1 Pincoin for a high score and 2 Pincoins for a grand champion score. There will only be 21 million possible Pincoins, just like Bitcoin.
Games would need to be on a network together for "mining" (playing) and high scores would need to be regularly beat to generate more Pincoins.
A new glass on detection system and required video surveillance for verification is required for every game on the Pincoin network.

Here's another one, BeefCoin. Supporting super markets provide a unique code for every pound of beef purchased. Buy 2 lbs of ground beef? You get 1 BeefCoin. Buy 24oz of fillet mignon? You get 10 BeefCoins!
