Is there an electronic bank or virtual money for table games?

Question

Fintech

Hello! There was such an idea: to have an intra-family electronic currency that could be used both for board games and just as bonuses for washed dishes or something like that. :) You can, of course, print papers and use them, but you must admit that a virtual online bank with electronic wallets for each family member is much more interesting! It would be especially cool if it were possible to check the balance from the mobile application and transfer game money to other participants.
Perhaps there are some services, applications, or something similar, where one could create an account with such a toy bank and wallets for all participants.
Unfortunately, I couldn't google anything like that. The maximum that I found is the "Monopoly Credit Card Terminal" application, but this is far from the main idea.

So what's wrong with modern cryptocurrencies?
There are hundreds of them now, and at the same time there will be an incentive for children to learn the basics of finance and financial literacy.
Bitcoins or Litecoins are certainly not bad, although you can start with something simpler, the main thing is that the infrastructure has already been developed.
