How Does the Casino Kings Sign-Up Offer Compare to Other Bookmakers?

Here’s a quick comparison of the Casino Kings offer versus other top UK sportsbook welcome offers.

Are Casino Kings Odds Fair?

Punters can evaluate odds fairness by calculating the overround (bookmaker’s margin). 

This is the sum of the implied probabilities of all outcomes in a market, and any total above 100% represents the bookmaker’s edge. 

A margin of around 105% is considered fair, whereas a margin of 110% or higher indicates less competitive odds.

To gauge odds fairness, we compared the combined odds (overround) on different games, which you can check out below.

Crystal Palace v Liverpool (Community Shield)

Crystal Palace: 5.20

Draw: 4.33

Liverpool: 1.56

Overround: 106.43%

Aberdeen v Celtic (Scottish Premiership)

Aberdeen: 6.40

Draw: 4.75

Celtic: 1.39

Overround: 108.62%

Viktoria Plzen v Rangers (Champions League Qualifying)

Viktoria Plzen: 1.73

Draw: 3.56

Rangers: 3.84

Overround: 111.94%

These three examples demonstrate that on higher-profile matches and events, Casino King offers competitive odds, but is less competitive on lower-profile matches. 

Overall, the odds offered at Casino Kings vary depending on the event, so it’s always worth comparing prices on less popular leagues and events.

How Competitive Are Casino Kings Odds?

Jannik Sinner – Men’s US Open (Tennis)
