Not all casino bets are created equal. Some give the house only a razor-thin edge. Others are designed to drain your bankroll at an alarming rate. Understanding the difference is one of the few real advantages a player can have.
Here is a clear, no-nonsense breakdown of the smartest and dumbest bets you will find on a casino floor (or online), ranked primarily by house edge — the mathematical advantage the casino holds over time.
The Smartest Bets in the Casino
These are the wagers that give you the best long-term odds when played correctly.
1. Blackjack (with Basic Strategy) – House Edge ≈ 0.5%
When you play perfect basic strategy and avoid side bets, blackjack offers one of the lowest house edges available. Single-deck and well-ruled multi-deck games can drop even lower. The key is discipline: never take insurance, never deviate from the strategy chart on emotion, and never play games with poor rules (6:5 payouts, no double after split, etc.).
2. Craps – Pass Line / Don’t Pass + Full Odds – House Edge ≈ 0.0–1.41%
The Pass Line and Don’t Pass bets sit at about 1.41%. Once a point is established, the free Odds bet behind them carries zero house edge. Taking maximum odds is one of the best moves in the entire casino. Avoid almost every other bet on the layout.
3. Baccarat – Banker Bet – House Edge ≈ 1.06%
Simple, fast, and excellent odds. The Banker bet is statistically the strongest of the three main options (Player is ≈ 1.24%, Tie is a disaster). Commission on winning Banker bets is the price of the low edge — pay it and move on.
4. Full-Pay Video Poker (Jacks or Better 9/6 and similar) – House Edge ≈ 0.5% or lower
With perfect strategy and a full-pay machine, video poker can rival or beat blackjack. Always check the paytable. “Full pay” means the machine returns close to 99.5%+ with optimal play. Anything less and the edge climbs quickly.
5. European or French Roulette (Single Zero) – House Edge ≈ 2.70% (or 1.35% with La Partage)
Still higher than the top table games, but dramatically better than American double-zero roulette. If you must play roulette, never sit at a wheel with two zeros.
The Dumbest Bets in the Casino
These are the wagers that exist primarily to separate players from their money as efficiently as possible.
1. Keno – House Edge 25–40%
One of the worst propositions in the building. The house edge is enormous and the game is slow. Avoid it completely.
2. Big Six / Wheel of Fortune / Money Wheel – House Edge 11–24%
Colourful, loud, and terrible. The higher the payout number on the wheel, the worse the odds for the player.
3. Most Slot Machines – House Edge 5–15%+ (sometimes higher)
While some modern video slots publish RTPs of 96%+, many still sit well below that, especially progressives and older machines. High volatility combined with a steep edge makes slots a fast way to lose money for most players.
4. American Roulette (Double Zero) – House Edge 5.26%
The extra zero nearly doubles the house edge compared with European roulette. There is almost never a good reason to play it when a single-zero wheel is available.
5. Side Bets and Proposition Bets
– Blackjack Insurance ≈ 7%+
– Any Pair / Perfect Pairs / 21+3 side bets → frequently 5–15%
– Craps Hardways, Any Seven, Horn bets → 9–16%+
– Baccarat Tie bet ≈ 14.4%
– Sic Bo and other specialty dice games → many bets exceed 10–30%
These bets look exciting and pay big when they hit. That is exactly why they exist. The casino wants you to take them.
Quick Decision Framework
| Goal | Best Choice | Avoid |
|---|---|---|
| Lowest possible edge | Blackjack (basic strategy) or full-pay video poker | Side bets, insurance |
| Simple & strong | Baccarat Banker | Tie bet |
| Social & good odds | Craps Pass/Don’t Pass + Odds | Hardways, proposition bets |
| Pure chance, better odds | European Roulette | American Roulette, Big Six |
| Entertainment only | Low-volatility slots with known high RTP | Progressive slots, Keno |
Final Reality Check
Even the smartest bets still carry a house edge. Over enough hands or rolls, the casino will win. The goal of choosing better bets is not to “beat the house” long-term — it is to lose more slowly, extend your playing time, and give yourself a realistic chance of walking away ahead on any given session.
Set a strict loss limit before you start.
Never chase.
Never increase your bet size because you are “due.”
And when the session is no longer fun, leave.
The smartest bet you can make in a casino is the decision to treat it as paid entertainment with a known cost — not as a way to make money.
