Good to know about online slots

you're new to the experience of playing slots online, and understanding what is going on can be overwhelming. Here are a few paragraphs explaining basic slot terminology that's good to know while browsing our list of games.

RTP: Return to Player; a theoretical percentage dictating the overall return to player percentage over an infinite amount of spins. An independent ISO-certified testing facility verifies this percentage before public release to ensure game security, fairness, and accreditation. Using the Jammin' Jars 2 slot as an example with its 95.45% RTP indicating that this percentage of the total amount of money wagered on that game will be paid out as winnings to players, while the house keeps the remaining 4.55%

Volatility: Also known as variance or volatility, it is a term used to describe the frequency of payouts but also their size of them. If you see the volatility level before you play it, you have a pretty good idea of what to expect. The standard classes consist of "low," "medium," and "high." There are also "very high" or "extreme," which have become increasingly popular since 2018 due to the large payouts. To give you an idea of the spectrum, San Quentin xWays slot is a highly volatile slot that rarely pays, but when it does, it might result in a win that's multiplied 150.000x times your stake, while low volatility titles rarely pay out more than 1.000x your stake.

Max Win: A term that describes the maximum payout observed during game testing before fairness and an unexpected results certification and usually noted in sum +" x" denoting the value to multiply the stake you're playing win. A max success of 100.000x on a $0.10 stake means the max amount you can win in a single spin is $5.000.

Max Win Cap: This term is an extension of the "max win" and describes the actual cap on the amount you can win in your respective currency. For most players, it doesn't" make a difference. It does, however, for the casino should a high roller do $100 spins. The cap reduces the casinos' exposure to risk in the event of a massive win. For example, a regular player doing $10 spins on a game with a $500.000 max win cap will be paid if hitting a 50.000x on San Quentin xWays, whereas a high roller doing the same on $100 spins will not. The most prominent online casinos rarely enforce this rule. Still, it is notoriously abused in many forms (especially when playing with bonus funds) by shady casino operators (usually non-regulated ones) to avoid paying players. The "max win" and "max win cap" rules co-exist, where the first takes precedence over the other. Please note that the max win cap does not apply to jackpot slots with progressive jackpots.

Slot volatility: Fewer and bigger wins - or frequent, smaller wins?

Volatility concerning slots describes risk when playing a slot machine. That risk boils down to how likely you are to bust your bankroll before winning anything significant (or small, for that matter). While "volatility" is the preferred term players use, some use the term "variance"; different word - same thing.

Low volatility/variance slots

Slot titles with a low-level pay out much more frequently. The winnings are much smaller compared to higher levels. They're a perfect option if you're a new player wanting to test the waters, as they extend the "lifetime" of your bankroll considerably. Don't expect to win more than 1.000x your bet size, playing low volatility slots.

Medium volatility/variance slots

Slot titles on the medium volatility scale sit between the lowest and the highest levels. They're "all-rounders" with a good balance between payout frequency and the size of winnings, increasing the lifespan of your bankroll while also perfectly capable of dishing out +1.000x your bet size in prizes.

High volatility/variance slots

Since casino streaming started becoming popular, high volatility slots became the new, golden standard for most game developers as both players and the audience wanted to see bigger and bigger wins. They are known to cripple player bankrolls and dish out frequent Deadspin streaks (game rounds with no winnings). Their appeal, however, is their max win potential.

Online Slots FAQ

What are free spins?

Free spins are free game rounds on online slots where you play with the casino's money as a single - or a part of a more extensive - promotional campaign. There are two types of free spins you need to know about; 1) Wager free spins and 2) non-wager free spins.

What are wager and non-wager free spins?

Wager-free spins come with a wagering requirement on any winnings derived from using these, while those that are wager-free do not. The latter means you can keep the money you've won without repeatedly playing through it before withdrawing.

What is a wagering requirement?

A wagering requirement in online gambling, bonuses, and free spins means you must play through your funds at pre-determined times before clearing them. An example would be if you had a 10x wagering requirement on your free spin winnings, meaning that you'd have to wager 100 USD if you won 10 USD before cashing out those winnings.

What does slot RTP mean?

When used in the same context as online slots, RTP stands for "Return to Player." It states the expected payouts to players given a theoretically infinite amount of game rounds/spins. It's a number needing certification by multiple (independent) testing facilities and third parties before being approved as the official game RTP.

Is there a strategy for playing slots that works?

The best strategy you can apply for playing slots online is to accept that there isn't one that will make you win. All slots have a predefined RTP range, which always gives the house a certain percentage of an edge against you. You can't beat the house. Playing slots is entertainment, and there isn't a single strategy for playing slots that will make you a winning player.

What if I want to test a slot's strategy?

The staff at CasinoGrounds receives messages from players who claim that they have a working slots strategy every week. Despite their efforts to prove their claims with big win clips and screenshots, their winnings are due to sheer luck and random chance. There's no online slot strategy that will work unless the game is flawed. All operators have a clause in their terms and conditions stipulating that the casino can rightfully confiscate winnings derived from faulty games, bonus abuse, or bug exploitation.
