The Tough Edge of Keno
Deep Dive into Keno’s Edge
The Huge House Win
Keno pins players against a tough 20% to 40% house edge.
This equals a loss of $20-$40 for every $100 gambled, making it one of the toughest games for players in casinos.
The Math of Odds
The way Keno is played is by picking numbers from 80 options, with 20 numbers ending up drawn.
Picking a 10-spot game puts players against rough odds of 1 in 8.9 million to hit all their picks. Even a smaller win of 5 out of 10 is about 1 in 323.
Payouts and Real Odds
The big gap between payouts and real odds creates a huge edge for the house.
While the game might pay 10,000 to 1 for nailing all 10 numbers, fair odds would be close to 8.9 million to 1.
This huge odds gap helps make Keno one of the worst for house edge.
Big Risk Points
- High House Edge: 20-40% gain for the casino
- Tough Odds: Unreal chances of hitting all numbers
- Payout vs. Odds: Big gap
- Statistical Downside: Lower payback
The Real Deal on Slot Machines
Slot Machine Paybacks
Today’s Slot House Edges
Modern slot machines keep house edges between 2% to 15%, different with each game and place.
Penny slots are the toughest, with returns only between 85-88%, while dollar slots hard hit a 95% payback rate.
Expect loss of $5-$15 per $100 played through time.
Fast Play Hits Hard
The speed of slot machine games is a core issue.
With 600 spins each hour at $1 per spin, you bet $600 against the house edge every hour. At a 10% house win, that’s about $60 gone every hour, way more than most old school table games.
The Magic of Random Spins and Jackpots
Random number generators (RNGs) make sure each spin is its own thing, with no way to guess or beat the system.
Progressive jackpots slash basic game returns as part of each bet grows the big win.
Slot volatility means a wide range between expected and actual payback, especially over short plays.
The Big Wheel of Loss
Wheel of Fortune: Betting and Edges

House Edge and The Odds
The Wheel of Fortune is an eye-catcher but it has a big 11% to 24% edge for the house.
This edge changes with different wheel setups and bet choices.
The Game Math
A typical casino wheel has 54 parts, including:
- Different cash parts ($1, $2, $5, $10, $20)
- Two parts where you straight lose
- Best payout spots which give back 45:1
- 1.85% shot (1/54) at hitting the top payout
Comparing Casino Games
The odds for the Wheel of Fortune are way worse than most old casino games:
- Wheel of Fortune: House win of 11-24%
- Blackjack: House win about 0.5%
- American Roulette: House win about 5.26%
What to Expect
Betting $1 on a single number usually eats about 11 cents each spin over time.
Despite the many ways to bet, the math keeps the house win steady across all betting ways.
Note, these odds are way tougher than most tables.

The Two Zero Roulette Deal
Understanding Double Zero Roulette Odds
The Math Behind It
The double zero roulette is worse for players than the European version, with a 5.26% edge for the house against 2.70%.
This big gap comes from an extra zero (00) on the American wheel, bumping up the total numbers from 37 to 38 but keeping the same payout rates.
Odds and Payouts Study
The two zeros (0 and 00) add more ways to lose while keeping normal payouts.
A straight-up bet on one number pays 35 to 1, though true odds are 37 to 1. This math gap keeps the house winning no matter what.
What to Expect
Edge Details
Putting down $100 on double zero roulette usually ends in a $5.26 loss over time, making it one of the tougher table games. 공식 인증업체 목록

- Edge for the House: 5.26%
