Knowing the odds on any casino game is the first filter. Smart players spend their time on the games with the best player odds. Inside a game, they also know which bets are close and which are a donation.
Dice, blackjack, and baccarat carry the best player odds on the floor. That is why they get the bulk of serious play. Some vehicles are so bad they should be avoided as a habit: the Wheel of Fortune is the exhibit. Keno is a dinner tax. Slots are the most popular game in the house and the one where a tight loss limit matters most — the longer you sit, the more likely the session is a loss.
Short sessions do two jobs: they cap the damage, and they give you a chance to walk when you are ahead. Every regular has watched a nice win turn into a loss by staying for one more shoe.
Even-money versus a 35-to-1 single number is a constant itch. Tracking how long a number has been cold is not a system. The wheel has no memory. If you make that bet, make it small and call it entertainment.
Set hourly session limits. Four-hour stretches are plenty. Treat each session as its own book. When you are winning, you may press a little. When you are losing, you do not “win it back” by changing the math.
