If you're looking to stretch your bankroll and maximize expected value when you play Grande Vegas slots, you need to understand how the Return to Player percentage is the single most important factor in game selection. By targeting the best RTG slots with high RTPs you can reduce the house advantage significantly.
Regardless of whether you prefer low- or high-payout games, navigating the Grande Vegas Casino floor or digital lobby with an eye on RTP allows you to convert a standard entertainment session into a calculated, strategic gaming event. This Grande Vegas online casino guide breaks down the slots that deliver the highest returns while offering the best in slots entertainment so you have the mathematical roadmap needed to pick the smartest bets and protect your cash stack.
Explaining RTP
The Return to Player (RTP) percentage is the theoretical percentage of all wagered money that a casino game pays back to players over a large volume of plays. It's the inverse of the House Edge – if the House Edge of a game is 5%, the RTP of that game is 95%. Statistically, for every $100 wagered on that game over time, $95 is returned to the player pool in winnings and the casino retains $5 as gross revenue.
RTP is a long-term statistical average. It does not guarantee short-term results. Even if you're playing a high RTP game, due to statistical variance, during the course of a single session, you could possibly lose 100% of your stake or, conversely, you could win 500x your wager.
Things to Take Into Account
Together with the RTP, there are other factors that you should take into account when choosing your slot machine.
Volatility Matters
Two games can both feature a 96^ RTP but play completely differently. Low volatility games offer frequent, yet smaller wins, which is a better game for players who are worried about keeping their bankroll stable. The wins in high volatility games are less frequent but they're higher, including potential payouts for jackpots and bonus features.
Base Game vs. Total RTP
Some progressive or other jackpot-type games split their total RTP. For example, a slot might have an overall 95% RTP but the base game's RTP is significantly lower because of the contribution that is placed in the jackpot pool. So in total, the RTP is higher but that kicks in only if you bet the minimum wager to join the jackpot competition and vie for that elusive prize.
How to Find High RTP Games
To find high RTP games:
- Review the in-game playtable/help screen. The RTP should appear inside the game's paytable – if not on the casino site, then on the game developer site.
- Check the game developer's technical audits. Independent testing laboratories (i.e. iTechLabs, Gaming Laboratories International, etc) place audit seals where you can click to find the verified payout percentages of each game.
