Do you remember snake game? The game where you get fat by eating the object and end up increasing size and then reaching a stage where you eat your own tail. Another thing is that this would also means that the game would force you to play carefully avoiding the walls and the self touch. So it was a good game. 

Same concept has been created in the chainduel. You and other player would have to eat the object, called block. And you have to increase the size of the blockchain. And not to touch the wall or touch the opponent. This way you would win the game at the end. So this is a good addition of the Satoshi powered game where each game would require certain Satoshis to be added. 

In order for the chainduel function the paywall like satoshis is being created. Now coming back to games like these. They can appear simple but  they would make the developers enough money and also add to the economy. So it's a good game worth checking out. I found out about this game using the primal.net Nostr.
