They can either pick up the card on top of the discard pile or draw from the deck. The person on the dealer’s left goes first. The dealer turns over the top card on the remainder of the combined deck and creates the “discard pile”. Jokers are wild and 3’s are wild (because you have 3 cards). For the first round, each player is dealt 3 cards. Start by taking 2 standard decks of cards (including the jokers) and shuffling them together.
You “get rid” of your cards by grouping them into sets of 3 or more, all of the same card (ie three Queens) or having a straight flush. To be the first player each round to “Tic” and get rid of all of your cards, and to have the lowest number of points at the end of the game. Any more than that makes the game get really slow. You can play with 2 players (HH and I do it all the time) and up to 6 players. I think there are several different versions of Tic, but this is the way that we were taught to play.
