How to choose a generous slot machine to win at an online casino?

How to choose a generous slot at online casino
We will teach you the strategy that will help you to choose a generous slot in an online casino, depending on its behaviour. You will learn how to identify which slot can give you more winning with less risk. Pay attention, but if you believe in the prize pools in slots and casinos, then this strategy is useless for you. As we said, there is a theory that the slots from (especially those from NetEnt) behave the same in the demo and real money play. So, like this, all money will be collected, from games in demo mode, and then every player will switch to real play.

The behaviour of the slot machine in demo mode

The strategy's essence is to choose a profitable slot machine, based on its behaviour in free mode. Considering that all Netent slots are on the company's server (it's mean that online casinos are only receiving and paying-out money) then all demo versions of games are also the same for all online casinos.

There are the following states (mood) of slots

  • Evolution
    Positive (Hot). Slot machines with a positive balance in the prize pool (players lost more money than won). These are the most potential slot machines, as they can "fire" with huge winning at any moment.
  • Negative (Cold). Slots with a negative balance in the prize pool (paid-out a big win recently and now needs money to fill up the prize pool). You should avoid playing in such slots.
  • Neutral. Slot machine with a Neutral mood (have zero in the prize pool). Usually, such a slot machine will keep the account balance and then gradually reducing it

An ideal online slot

In a perfect situation, the player should choose a hot slot machine that has extra money in its prize pool (players lost much more than the slot paid as winnings). To find such a slot, you should test the mood of various slots in free demo mode.

How to identify that slot has a positive balance and ready to pay

  • Go to the "Free casino games" section, and select the slot machine. While you are choosing a slot, it is worth considering the RTP (return to player percentage), slot's volatility, wagering rating, the probability of triggering the bonus feature and distribution of the prize pool (during usual spins and the bonus feature). On the overview page, you will also find the hidden data of the slot machine (the length of the cycle, dispersion of winning) and feedback of the tester.
  • Start slot in free demo mode, with the bet (and the number of lines) that you are planning to play for real money. I recommend that first familiarise yourself with the articles: the dispersion in slots and the length of cycles.
  • While you are changing the bets, try to understand the reaction of the chosen slot on each denomination. If there are a lot of winnings and bonus features are often triggering, then the slot is "warm," and it has big potential to "firing" with big winning.
  • If fun money is lost, refresh the page with the demo mode and change the bet per single spin. We are repeating these actions until we find the optimal bet. If the slot is taking money away on all denominations, we must choose another slot machine and test it in free mode from the very beginning. I recommend that you read the article "Change in the value and quantity of coins per pay line".
  • It is essential to understand that a single big winning can be an exception, like in a situation if you have already lost a lot, it can give you a single win, which will cover around 50%-70% of the money lost. But again, this will be an exception.
  • If the warm slot is found, we begin to play for the real money on it. It is essential to use the same number of lines and an equal bet per single spin that was used in free mode.
  • I recommend you start learning these tactics with the minimum bets both in free testing and for real money. You will save a lot of money while learning the strategy. When you see that this strategy works, then you can switch it to your usual bets.
  • I advise you to choose 5-10 favourite slot machines with a good RTP (return to player percentage) and test them first. If all these games do not show the desired result in demo testing, it is better to stop or choose another software developer (Microgaming or NYX).
  • One of the main factors that influence on maximum winning is the amount of money in your casino account and current bet per single spin. We recommend having at least 200 bets in the balance. It depends on the length of the cycle of the slot
  • Our recommendation is to combine the testing strategy of Netent slots in free mode with the getting of the positive mathematical expectation of winning in the online casino.
  • Over time, you will learn to identify warm slots. You only need experience and time.

Indirect signs

Some signs show the current state of the slot machine. In such slot machines, triggering bonuses or free spins at an exact bet occurs more often.

In our opinion, there is some connection between the numerical symbols and the slot's status. These signs can be two scatter symbols on the first reels, as well as the slot's behaviour will change if you increase or decrease the total bet. You can expect a real profit when you start noticing that.


  • Big Win
    Imagine several pools with a lot of fish. Fish cannot move from one pool to another. Fish is the money that is lost. Players are fishers, and each online casino is as a pool. There is some algorithm that is used as a correction that regulates the number of "pecking" fish. According to our observations, this algorithm is updated once a month (as the calculation takes place between software, casinos and affiliates). It is important to get acquainted with the prize pool theory as it influences the big winning.
  • In other words, if you are the only player in a new online casino that does not belong to any network, then you will not merely have a chance of a big win before losing a lot. The prize pool will consist only of a sum of your bets, and over time you will hit a big win, which will be 90-95% of the sum of your total deposits

Tips and recommendations

  • We recommend that you start playing for real money only after going through all the steps described above. It is important not to have a break between the end of tests in the demo and the beginning of the game for the real money. Because during this period, maybe somebody wins a large bank and change the sequence of issuance (the slot will behave differently).
  • Try not to choose new games. At the time of the release of the new slot machine, despite the declared RTP (return to player percentage), it takes much more money than it gives out, forming a prize pool for winning. It is better to wait for a few months.
  • Choose your favourite slots and analyse them in the demo. Spend more time investigating them in demo mode and less for the real money gambling. 
  • Do not play with your last coin, and do not borrow money for gambling.
  • Choose only trusted online casinos for real money gambling. In this case, we can help you in a difficult situation. Check out their list, by clicking on the link below:
