How to find the best bonus slots with Slot Tracker

Let’s admit it: unless you’d like to keep it very simple by playing classic slots with almost zero features, when we play online slots what we’re really after is the bonus round. This is where the biggest rewards are to be had, and where the excitement truly picks up. In certain online slot machines with bonus games, this bonus round (which can be either a free spins round or another bonus game) can be very difficult to get to, and triggering it will require a good number of base game spins, most of which will not pay out at all. In other games, the bonus might be easier to trigger, but then you might find that it’s not as rewarding as you hoped.

For this purpose, Slot Tracker has a number of figures related to slot bonuses to help you figure out which are the best bonus slots to play online. In this article, we’ll explain what these figures mean in more detail so you can start making use of them as part of your slot strategy.

Bonus slots data in Slot Tracker

If you head to the ‘Slots’ tab in Slot Tracker, you’ll find the Bonus Details for the online slot machines with bonus games that you have played. These include:

Total Bonuses the number of bonus rounds you have triggered on that particular slot.

Best bonus – your best win from all the bonuses you triggered on the slot. You’ll be able to see how much you staked when you won that bonus, how much you won, and how many times your stake that bonus win amounts to.

Average bonus win – this is a great indicator of what kind of slot wins to expect from a bonus round. The average bonus win is displayed an amount multiplied by your stake, with the actual amount in your currency displayed in brackets.

Worst bonus – this is the lowest payout you have been awarded from a bonus round. Similar to best bonus, you also get to see how much you had staked and the amount of times your bet which the win has amounted to.

Bonus frequency – this is given as a fraction as well as a percentage of the total spins you have made on a particular slot.

Spins ago – the number of spins since you last triggered a bonus round on that slot. This will give you an idea of how long you need to spin, although it can also be misleading since slot outcomes are totally random and you may trigger the next bonus after just a couple of spins!

Community statistics for slot bonuses

Apart from your own bonus statistics, Slot Tracker will also display the bonus statistics generated by the Slot Tracker Community, i.e. by all the players that are connected to the Slot Tracker network. You’ll be able to see the average bonus win for the community, as well as the bonus frequency. Not only will this give you a better indication of which ones are the best bonus slots to play, but it will also enable you to compare this data against your own to see how well you’ve been doing on the same slots compared to other players. In the case of most slots, one can also assume that the data for the best win is also the result of a bonus round, since this is where the highest slot wins are to be had.

£ 100 bonus on first deposit and 100 bonus spins on first deposit.
18+ BeGambleAware 18+ | BeGambleAware | t&c Apply | New customers only. Min. £10 deposit. 30x wagering requirement on deposit + bonus amount and free spins winnings. Bonus funds are subject to a 28-day expiry. Spins are worth 20p and are available on Cleopatra slot only, valid for 7 days. Max. conversion of 5x the bonus amount applies.

Using the Win Ratio Chart

One other thing to look out for if you’re looking for the best bonus slots is the Win Ratio Chart in Slot Tracker. The chart displays the percentage of slot wins that resulted from the base game as well as the percentage that resulted from the bonus game. This will give you a very good idea of the payout structure of slot machines with bonus games.

If you notice that only a small fraction of wins were had from the base game, this may mean that the slot’s bonus game is very rewarding, whereas the base game may be quite uneventful. If this is the case, you might want to consider the bonus frequency before playing this slot for real money again, since if this is on the low side, you will risk losing too much during the base game.

We like to go for online slot machines with bonus games that have a decent base game win percentage combined with a good bonus frequency to make sure that there will be enough base game wins to sustain our bankroll until we trigger the bonus game. However, your choice of bonus slots will also depend on your personal preferences, since if you like slots with high volatility, you might be ready to risk a poor base game for the chance to trigger the bonus and win big!
