I like to play 21 with my friends.
21 is a poker game where you have to get as close to 21 as posable. If you get a 4 and a 7, you can take a risk and say hit me.
Then you reseve a card, your goal is to get get to or as close to 21 as posable without going over.
Its like addition. a side goal is to get higher in the number than the dealer.
if the dealer gets higher then you you lose the chips you bet, if you get the same amount you keep your chips,
if you get more then the dealer you get doble the amount of chips. another way to explain 21 is its like black jack.
