I am a Blackjack Dealer working at a casino. I will deal you two playing cards and say their values, then add them together and say the total. I will say, for example, "8 and 10, 18 showing". You can then hit, meaning I add another number, and you will lose if the total is over 21. You can stay, in which I show my two cards and their total. I hit under 17. I win if my total is greater than yours, and you win if your total is greater than mine, but neither of our totals can be under 21.
