Skip the slots, 97% only means that one lucky person gets a jackpot, and the rest get to feed the machines. Keno is 25% house advantage, and worse. To count at "21" you need to practice about a year, and play perfect strategy, even then if they don't deal far enough into the deck, counting is usless. Video Poker is great entertainmemnt, and if you use perfect play, the only way to win is hit a Royal Flush. Roulette is actually inexpensive to play. A $20 stack of 50c wheel checks will last you over an hour.

That leaves you with some strange inventions, the big wheel, and sucker bets, EXCEPT... Baccarat and Craps. Good thing about baccarat is that it's almost impossible to make a bad bet. The rules control everything. If you can find a $5 table, it's the best bet in the casino. ie lowest house odds.

So here's the scoop on Craps. Reason #1, in many casinos, it's the only place you can find $1 chips! After that, the house percentage is 1.62 or lower on all the bets, you want to make. I've included a picture of the way the table should look, without all the casino's distractions.

Here are the ONLY bets on the crap table.
1) Pass or Don't Pass (1.41 / 1.40)
2) Come or Don't Come (same as above)
3) Place the number 6 (1.52)
4) Place the number 8 (1.52)
5) Take 1X odds (.8%), Double Odds (.6%)

That's all folks! LOL
