Casino Games with the Best Odds: A Guide to High RTP & House Edge

“The house always wins.” It is the oldest saying in gambling, and mathematically, it is absolutely true. Every single game in an online casino is programmed to give the operator a slight mathematical advantage over the long term.

However, not all casino games are created equal. If you want to stretch your Canadian Dollars further, play longer, and give yourself the absolute best chance of cashing out a profit, you need to stop playing games based on flashy graphics and start playing games based on math.

Here is our expert guide to understanding the House Edge and the casino games that offer you the best odds of winning.

What are House Edge and RTP?

Before we look at the games, you need to understand the two most important terms in iGaming:

1. House Edge: This is the mathematical advantage the casino has over you, expressed as a percentage. If a game has a 5% house edge, the casino expects to keep C$5 for every C$100 wagered over the long run. You want this number to be as low as possible.
2. RTP (Return to Player): This is the exact opposite of the house edge. It is the percentage of wagered money that a game will pay back to players over time. If a game has an RTP of 95%, the house edge is 5%. You want this number to be as high as possible.

Now, let’s rank the best games on the casino floor based on their odds.

1. Blackjack (Single Deck)

• House Edge: ~0.5%
• Skill Level Required: High

Blackjack is the undisputed king of casino odds. If you play using a mathematically perfect “Basic Strategy” (a chart that tells you exactly when to hit, stand, double, or split based on your cards and the dealer’s upcard), you can reduce the casino’s advantage to a mere half of a percent.

Expert Tip: Always look for tables that pay 3:2 for a Blackjack. Avoid tables that pay 6:5, as this seemingly small rule change quadruples the house edge!

2. Video Poker (Jacks or Better)

• House Edge: ~0.46%
• Skill Level Required: High

Video poker looks like a slot machine, but it plays like a game of skill. In variants like 9/6 Jacks or Better (meaning a Full House pays 9x and a Flush pays 6x), playing perfectly can yield an RTP of 99.54%. Some rare video poker machines even offer over 100% RTP under specific conditions, though casinos heavily restrict bonus clearing on these games.

3. Baccarat (Betting on the Banker)

• House Edge: 1.06%
• Skill Level Required: Low

Baccarat is the game of choice for high rollers (and James Bond) for a reason: the odds are incredibly good, and it requires zero skill. You simply bet on whether the “Player” hand or the “Banker” hand will win.

Mathematically, the Banker hand wins slightly more often than the Player hand. Even after paying the standard 5% commission on Banker wins, the house edge remains a tiny 1.06%. Just never bet on the “Tie”—the house edge on a Tie bet is a massive 14.36%!

4. Roulette (European/French)

• House Edge: 2.70% (European) / 1.35% (French)
• Skill Level Required: Low

If you love Roulette, the most important rule is to never play American Roulette. The American wheel has both a single zero (0) and a double zero (00), which pushes the house edge to a brutal 5.26%.

Always look for European Roulette (single zero only), which cuts the house edge in half to 2.70%. If you can find French Roulette with the “La Partage” rule (which gives you half your even-money bet back if the ball lands on zero), the house edge drops to an incredible 1.35%.

What About Online Slots?

• House Edge: 2% to 15%
• Skill Level Required: None

Slots are the most popular games in Canada, but they also have the wildest variance in odds. The casino has a much larger advantage here. However, software providers like NetEnt, Microgaming, and Pragmatic Play publicize the RTP of their slot games.

If you are going to play slots, never play a game with an RTP lower than 96%. Games like Blood Suckers (98% RTP) or Mega Joker (up to 99% RTP) are legendary among smart players, which is why casinos often exclude them from bonus wagering requirements.

Summary: Play Smart
