Casino Games and Maths – What Do They Have In Common

It is pretty apparent how casino operators earn their money. Their incomes don’t hinge on luck but on mathematical laws predominantly. It is solely about mathematics. Of course, exceptions occur from time to time, but in the long run casinos are always the victors. That is because they have a mathematical advantage over players. Mathematical percentages are numbers, and numbers never tell you lies. It is obvious that casinos wouldn’t offer their gambling services at all without having house edge. 

There are enough critics that suggest calling casinos the gaming market is incorrect. The explanation is that although casinos can be called gambling establishments, their operations aren’t based on gambling. It is the reliance on math laws and principles to make sure casinos make more than enough money to pay out debts, interest and other expenses.

Surprisingly, some casino fervent players may not know in detail how casinos benefit from exploiting mathematical laws. Of course, by having a house advantage, casino operators make their incomes. 

Satisfying Players’ Tastes 

Also, it is imperative for casino operators to learn how to provide entertainment for players. For the majority of punters, playing casino games is solely about getting fun and exhilaration. This way, adults can find a way to get away from pressures at jobs. But if the house edge of the casino players are about to kick off playing is too high, gamblers might consider withdrawing from such a platform. So, depending on players’ whims and tastes, casino operators and their games can either fail to satisfy punters’ preferences or succeed in it. And even irrespective of the fun players might get, if casinos don’t pay winnings often, there is a high likelihood players won’t select that platform. 

House Edge 

The unpalatable truth for the majority of players is that gambling platforms benefit from establishing casino games. This is because the house advantage keeps them afloat. Nevertheless, there are more than enough casino operators paying out winnings at lesser house edges. Having this in mind could make you win  slightly more than at other casino counterparts. 

For now, let’s take a closer look at the most traditional casino games and their odds of winning:

  • Craps
  • Roulette
  • Blackjack.


The game of craps is played using a playing table from 12 to 14 feet long. The maximum number of 16 punters could take part in playing craps simultaneously with 8 gamblers sitting on each side of the table.  

Players pass dice around in a clockwise direction. Once it is your turn, you just roll these dice. The very first attempt is a come out roll. A natural is a combination of dice when players roll either 7 or 11. If this happens, you win and reroll dice. On the other hand, combinations of 2,3 and 12 are called craps. Once you land these numbers, you lose the bet and have to make a roll again. 

As for odds, they vary depending on the exact numbers you land. For example, having 4 or 10 are 2-to-1 odds. 


The roulette game is all about spinning the playing wheel, the ball that falls on a slot and 38 chances to win. Of course, the European roulette doesn’t include the double zero slot, so there are 37 places where the ball can be located. Hence, the European roulette has higher winning probability than the American version. 

The table players make their bets on is divided into outside and inside bets. The table also contains numbers from 1 to 36 and places for zeros. Everything else is about outside bets. If you play the US roulette variation, every inside bet is of 5.26% house edge. The only exception is the 5-Number bet, it is calculated as a 7.89% house edge percentage. 


The uniqueness of the Blackjack game revolves around the fact that when punters play the basic strategy, the house edge doesn’t exceed 0.5%. Those who don’t make use of this tactic, play with a 2.74% house advantage. 

Basically, the blackjack game is played using 1,2,4,6 or 8 decks. The peculiarity is that the more decks are used, the more is the house edge because players can’t count cards in that situation. Besides, blackjack is the sole gambling game whose regulations differ from one casino to another. A great example is casinos in Atlantic City, where nearly all gambling platforms feature either 6 or 8 decks dealt using a shoe with face-up cards. 

On the other side of the coin, there are some land-based casinos in Las Vegas playing with just 1 or 2 card decks. Cards are dealt face down. It is natural that rules of blackjack may differ from one playing table to another in Las Vegas. 

Once you have finally decided to take a seat at the playing table, don’t forget to check out what the minimum and maximum bets are for the game. For example, this could be a $7 minimum bet and $2,000 maximum wager. Depending on how casinos are busy, brick-and-mortar casinos can adjust their betting limitations. 

Essence of Blackjack 

The aim of blackjack isn’t about beating other players at the table but defeating the dealer themselves. You are victorious in two cases:

  • When you have a 21 or less points in total and the dealers’ total is less
  • The dealer exceeds the 21-point limit, it implies that the dealer busts. 

In Conclusion 

Summarising, these are not all casino games enlisted here. One could find loads of more games with better odds than the aforementioned games.
