It's good and fun. The instruction could be clearer around the actual game play and flow. But, once you try, everything clicks together, and it's a really nice way to visualize how bitcoin works. Obviously, it's not 100% accurate, it cannot be and still be a game. But, mining, blocks, the chain of transactions, wallets. It's all there! And my kids 4-9 years old all were able to play (4 year old needing assistance of course). And they have been asking to play again.
I'm going to highly recommend it. If you have friends that like board games, this will give them language for understand bitcoin for when you inevitably start ranting about it. And for your kids, it gives them a mental structure for understand it for when you inevitably force them to setup their own nodes haha.
Give it a try!
