Question 1 of 10
0 / 0- Maths reviewed by Josh Miller
- Tested by Diana Westfield
This house edge quiz has ten questions, and every one of them puts two or three bets side by side that look alike but cost very different amounts. Red on a single-zero wheel or a double-zero one? Banker, Player or Tie? How bad is a 6 to 5 blackjack table, really? Each answer shows the maths in a couple of lines and links to the free CasinoCalcs calculator behind it. People who play regularly tend to score five or six. We’ve seen very few tens.
What the house edge quiz is testing
Think of the edge as the casino’s slice of every pound you put down, taken a little at a time. On red at a single-zero wheel it’s 2.7p per pound, and you only notice it over thousands of spins. That’s what makes these questions tricky. Nothing on the table tells you the edge. A bet that wins two times in three can cost exactly the same as one that wins once in 37, and something paying 3 to 1 can be a worse deal than something paying evens.
We set the questions on standard rules: European roulette with 37 pockets, eight-deck baccarat taking 5% commission, a six-deck blackjack shoe and a money wheel with 54 segments. Play somewhere with different rules and the numbers move. The best odds in the casino page lines the common bets up next to each other, and the RTP and house edge calculator turns any edge into what it costs at your stakes.
Getting all ten right won’t beat the casino. What it does is tell you where your entertainment is cheap and where it’s expensive, and that’s worth knowing before you sit down anywhere.
