Casino Games With the Highest House Edge: What to Avoid
While all casino games have a house edge, some games extract far more from players than others. Understanding which games carry the highest mathematical disadvantage helps you make informed choices about where to spend your entertainment budget. These games are not necessarily 'bad'—but you should know what they cost.

The Worst House Edges in the Casino
Keno leads the pack with a house edge of 25-29%, meaning the casino keeps roughly a quarter of every dollar wagered. The Big Six/Money Wheel follows at 11-24% depending on the segment. The baccarat Tie bet (14.36%) is one of the worst table game wagers. American Roulette's five-number bet (0-00-1-2-3) has a 7.89% edge—worse than every other roulette bet. Progressive slot side bets often exceed 20% house edge. These numbers are not opinions—they are mathematical facts.
- •Keno: 25-29% house edge
- •Big Six/Money Wheel: 11-24%
- •Baccarat Tie: 14.36%
- •American Roulette five-number: 7.89%
- •Progressive side bets: often 20%+
Why These Games Exist (Casino Revenue)
High house edge games exist because they are enormously profitable for casinos. Keno and Big Six operate with minimal staff costs—a few draws per hour with large margins. Slot machines with low RTP generate consistent revenue per square foot. The baccarat Tie bet capitalizes on the appeal of 8:1 payouts. Casinos deliberately place these games in high-traffic areas and market them with exciting visuals. The entertainment factor is real, but the mathematical cost is significantly higher than table games.
- •Low operating costs + high margins = profit
- •Keno: minimal staff, automated draws
- •Slots: revenue per square foot
- •Marketing emphasizes payouts, not odds
- •Entertainment value is the trade-off
Making Informed Choices
Knowing the house edge does not mean you must avoid all high-edge games. Some players enjoy Keno as a relaxed, social experience. Others play slots for the excitement of potential jackpots. The key is making informed choices: understand what you are paying per hour of entertainment. A $1 Keno bet every 5 minutes costs roughly $3/hour in expected losses. A $5 blackjack table might cost $2.50/hour. Treat the house edge as the price of entertainment and decide what you are willing to pay.
- •House edge is the price of entertainment
- •Know the cost per hour for your game
- •Keno: ~$3/hour at $1/bet every 5 min
- •Blackjack: ~$2.50/hour at $5/hand
- •Informed choice > uninformed avoidance
