This game share the same rule with the "21" DLC in Resident Evil 7.
The descriptions is fully recorded in the game, so maybe I won't talk about it here.
But I still wanna remind you that you should nod or shake your head(which means you should move your mouse back and forth quickly horizontally or vertically) to choose to get another cards or not.
Besides, you can play the game with some of your friends, or you can just play it alone and a villager named "Hoffman" would show up and be your opponent.
support minecraft version 1.15.2
Players are picked randomly, but those with the tag named "out" won't be picked(for example, if you enter the command "/tag @s add out", you won't be picked by the game; Besides, you can just enter "/tag @s remove out" if you wanna be picked again).Those haven't be picked would be a wither ghost and hanging around in the game room as a spectator.
If there's only you and no other players in the game，you can just play it with a villager.
It is fun that you can also just enter "/tag @s add out" to watch two villagers battle against each other.
The winner would gain 5 coins and the loser would lose 2 coins each time.
Coins could be used to purchase the skins of your number cards.
The modle of cards would be sometimes in a wrong position after player used the trump card "exchange", but it won't bother the game anyway.
