Playing in online casinos has been booming for years and is finding more and more enthusiastic followers. Most of them are pure fortune seekers. However, there are a few who like to take a more strategic approach and only want to play slots that are worthwhile.

In this article we give some clues for a profitable slot game, including slot features like wilds or scatters, but also bonuses from the casino like a no deposit casino bonus that you can play with for free.

Check the payout percentage of the slot machine

The most important criterion for checking the profitability of a casino game is the payout ratio. This is also called Return to Player and is abbreviated to RTP, which is an indication that you will often find. If you are dealing with an RTP of 95-97% then the slot pays out quite well. There are lower payouts at RTPs of 90% to 94%. Jackpot slots often have an even smaller RTP, sometimes under 90%.

You can usually find out how high the RTP is when you open the slot machine and click on the info symbol. There you will find information about the rules, the payouts and also the RTP. However, if it isn’t there, you can go to the manufacturer’s website and check there. Or you go to one of the numerous websites listing all possible slots. There you will usually find the RTP.

Check the volatility of the slot game

You can also check the so-called volatility of a game. Volatility describes how often and how much a slot machine pays out. A low volatility game has frequent but small payouts. With a high volatility machine, you will experience rare but bigger wins. If you know what volatility your selected game has, then you can adjust your strategy.

When the volatility is low, you can play with a small bankroll as wins will occur frequently. You might consider betting higher because you won’t win as much relative to the stake. On the other hand, if volatility is high, you should bring enough credit with you, because you may have to overcome a longer streak of bad luck. However, since there will be high payouts if you win, it can be worthwhile if you only play with small stakes.

Find out about free spins

See if the slot has a free spins feature. If one exists then you will be awarded a certain number of free spins when three or more scatter symbols appear on the playing field. With free spins you do not have to pay your own wager, but get free spins. With many slot machines it is possible that additional free spins can be triggered during the free spins.

Also inform about extra features!

A profitable slot machine speaks for itself when it has extra features such as bonus rounds or lucrative wild symbols. For example, bonus rounds may open up a game within the game, such as a wheel of fortune. There you can make additional profits. Wilds sometimes have the property of being so-called sticky wilds. This is the case during free spins, where the wilds will remain stuck in place on subsequent spins. So you have wilds on the field on every spin during the free spins. This can significantly increase your profits. Also, sometimes wilds come with a multiplier. Your win is multiplied by the multiplier, which increases your prize money again.

Is there a bonus for the slot?
