How to Choose the Best Slot Machines to Play at Casino

If you ask yourself what is the best slot machine to play to win, the most efficient and straightforward method for choosing a well-paying online slot machine is to check its tech specs in the first place. Look for online slot games with high RTP rates - higher than 90% for sure. Only progressive jackpot games can pay well with RTP rates around 85-88% because the key attribute of progressive jackpot slots is unlimited prize pool, not your typical in-game features.

The next criterion to check is the volatility level. If you know what level you need - high, medium, or low (or something in between) - you can predict your odds better and manage your budget more effectively.

The number of betways almost doesn’t influence anything, but you definitely want to check the minimum and maximum bet limits. This is especially important when you play a slot game with a casino bonus where the max bet limit is usually lower than the game’s limit.

And finally, look at the maximum win cap that the software studio set for the game. Obviously, the higher the max win cap, the better the game is likely to pay.

What Is RTP?

RTP is a Return To Player rate. It indicates how much return on their investment a player can get, statistically, if they play a slot game long enough. (Just for the record, it is not clear how long is “long enough”). Also, online casinos and software developers are not banks so “investment” is just a convenient term to explain the RTP rate.

In other words, RTP percentage shows how much money you can return as wins in the online slot after you play for real money for some time. RTP rates are always lower than 100% because there is also a house edge, a percentage that the casino takes as a payment for its services to players and studios. (So, RTP just can’t be 100%). Classic slots have around 95%. The highest payout casino games have around 96 - 98%.

As mentioned above, only progressive jackpots have lower RTP rates but pay even better than high volatility slots. However, if the player is lucky enough, they can get more than the average RTP percentage.

Table games that include not only luck but also skill promise even higher wins. If you prefer table games like blackjack or poker, they have higher RTP rates and pay well. The best game in terms of the RTP rate is blackjack, its return on investment reaches 99%. Yet, if you are not sure about your blackjack or poker skills, better play high RTP slots.

What is Volatility?

Volatility is the correlation between the frequency of hitting a winning symbol combination, and the size of each win. Of course, the higher the bet, the higher the win, and the type of symbol combination also influences the size of each win. However, frequent wins usually mean smaller sums, and this is the low volatility level. High volatility level, on the other hand, means that the wins in the high RTP slots are rare but higher.

As a rule, any best casino game to win money has higher than average volatility. High volatility slots usually offer specific mechanics, like Megaways, Hold and Win, etc. software providers like Netent prefer to release high RTP slots because this is a win-win product for all stakeholders.
