What is a House Edge?

Regardless of the game you play, you should know that the chances of the casino winning are higher. This happens because casino games are always designed to provide the house with an in-built advantage. The only game that is exempted from the edge is poker because it’s played between players. 

As aforesaid, the house edge represents the average gross profit that the casino expects to earn from each game. The least paying games have an edge of around 0.5% to 2%. Other games have relatively high edges of between 15% and 40%. Nevertheless, this does not mean that players have no chances of profiting from casino gaming. With the use of a proper strategy and bankroll management skills, Singaporean players can make good money from online entertainment.

House Edge vs. RTP Percentage

Often many novices are confused with the house edge and the Return to Player (RTP) percentage. There are significant differences between these two concepts.

While the house edge represents the long-term advantage of the casino, the RTP is what the player expects to gain in the end.

Actually, it’s more straightforward to calculate the house edge of a casino than determining the RTP of a game. Normally, the RTP percentage is always higher.

Calculating the House Edge in Casino Games

Calculating the house edge of casino games will seem complex at first. The good thing is that the formula for determining it is more or less the same. Whenever you want to calculate the edge, follow this method:

House Edge = (Odd Against Success – House Odds) x Probability of Success

If you convert this into a percentage, the formula will be as follows:

House Percentage = House Edge x 100

For example, the edge in the Sweet Bonanza slot machine is 3.49%. To determine what the casino will keep as profit for every $100 you bet, it’s essential to convert it to decimal and multiply by $100, which gives us $3.49 as profit.

How It Works with Online Slots

Online slots are without a doubt the most popular game across the globe. Most online casinos in Singapore offer dozens of variations ranging from traditional fruit machines to modern video slots. All slots use a random number generator (RNG) to generate results, in order to provide fair gaming, the best online casinos have slots from developers that are regularly tested, to ensure that their algorithms are not rigged, and provide fair RTP numbers, which should be 94% and up. One of the main features of slots is that they are purely based on luck as opposed to some table games that require skills. Though online slots are the most loved, they are often unfavorable to players. 

These games come with a house edge ranging between 3% to 10%. Some land-based casinos have machines with a high edge of up to 20%, meaning, only 80% of the winnings are paid back to players. But, the good thing about this game is that they allow you to play low stake bets. If you are looking for excitement or more playing time, this is probably the best choice. We highly recommend Singaporean players find information about the slot’s RTP before staking real money bets.
