You have to build up your gambling skill to be able to play the various games. The more you gamble, the better you get! Also, the higher level tables you are allowed to go to.

Slots
You just pull the lever and the wheels spin - there is no control here. You win or lose.

Video Poker
You have a 'coin value' for each coin you put into the machine, anywhere from $100 to $10,000. The payouts are right there on the screen. The payouts are in coins - so if it says "two pairs - 2" it means that for every coin you put in, you get 2 back if you get two pairs. Note that a given bank of machines randomly chooses a new dollar amount if you go to another bank and return to it.

How to play? You get 5 cards and press HOLD by each card you want to keep. Press DEAL again for a replacement on the non-held cards, and then whatever you end up with is your hand. If you don't know how to play poker, here are the definitions:

Royal Flush - A-K-Q-J-10 in a single suit (all hearts etc)
Straight Flush - any 5 in a row in a single suit
Four of a Kind - four of the same card (four 8s etc)
Full House - three of one card, two of the other (like three 8s and two 4s)
Flush - any five cards in the same suit (five hearts)
Straight - any five in a row regardless of suit
Three of a Kind - three of the same card (three 7s etc)
Two Pairs - two sets of pairs (two 3s and two 6s etc)
Jacks or Better - a pair of jacks, kings, queens or aces

You should always play the 5 coin maximum for a given machine, just in case you hit that royal flush. There are always super high payouts for the 5 coin royal flush. So it makes more sense to play 5 coins into a $100 coin machine vs a single coin into a $500 coin machine.

Wheel of Fortune
These are classic as the worst gambling odds in a casino. You don't even get to see the odds - you just bid based on dollar amounts on the table. The wheel has those same dollar values up on the wheel. If you lose, you of course lose your money. If you win, you keep your money PLUS you get that amount as indicated. So say you bet $1 on the $1 spot. If it lands on something other than $1, you lose. If you actually land on $1, then you get that $1 win plus your original $1 is still yours. You now have $2. If you bet $1 on the $40 and win, you keep your $1 plus you get $40 in winnings. Of course there are hardly any $40 spots on the wheel so that is the gamble :)

Blackjack
This is the traditional card game. The different tables have different maximum amounts on them. Your aim here is to get 21 points without going over. Whoever gets closest to 21 wins (you or the dealer). You place your best and then get 2 cards. He gets 2 cards - one is face down. If he gets blackjack (ace and 10/J/Q/K) he wins. You can 'hit' to get another card. 'double' means you get only one more card and your bet auto-doubles. Quit means you give up and forfeit your money. Stick means you stay on what you have right now. The dealer automatically hits if they have 16 or less, and stands on 17.

If you end up with 2 of the same card right at the beginning, you can split those into two separate hands and play each one separately. You can't split again after that. Blackjack (ace and jack) pays 2:1.

Roulette
The classic spinny ball game! The items to bet on on the left side (odd/even, red/black, 1-18/19-36) are all even money. Meaning if you bet $1 on red and win, you end up with $2 (your $1 bet plus the $1 in winnings). The second group in of 3:1 or 1st 12, 2nd 12 or 3rd 12 are now 2:1. If you bet $1, you get $2 in winnings and end up with $3.

If you bid just on one number, you get 35 in payback. So if you bet on 13 with $1, then you would get $35 in winnings. You can bet on two numbers at a time by putting a coin on the line, or 4 at a time (in the quadrant) or 6 at a time or 3 at a time (by betting on the line on the far right of the board). If you put your cursor on a line between two numbers (say between 1 and 2) means either of those two numbers win. That gets you $17 for every $1 you bet. If you bet on a row of 3 numbers, that's 11:1. A block of 4 numbers is 8:1. Six numbers at a time is 5:1.
