Average Trigger Points for Free Spins Bonus Slots

One question often a lot of online slot players ask regards the free spin bonus rounds. Namely, a lot of slot games can award Free Spins. This question is just how often does the free spins bonus round trigger on these kinds of slot games.

The only way you can get accurate facts and figures in regards to when, on average, the free spins rounds are going to be awarded to you is by knowing how many of the scatter symbols are placed on each reel along with the number of reel positions on every individual reel.


However, when you're nearing the time when the free spins on average land, you may wish to increase your stake. If they trigger, you end up with a larger winning payout than you would have when playing for lower stakes!

Below is our listing of several Microgaming software slot games. Alongside each of them, we have listed the average trigger points for each of their respective frees spin bonus games.

Bush Telegraph Slot

Should the fifteen-payline Bush Telegraph slot game take your fancy, it's for a reason.

Namely, Bush Telegraph gives you the chance of being awarded 10 free spins which play out on x3 multiplier values. This is only when you spin in three or more of the Scatter symbols. So, be aware that you'll trigger the free spins on average once every 143 spins in the base game.


There is an additional bonus game which can also be triggered when you play this slot. This is a simple pick to win type of bonus round, and is awarded when three or more of the Bonus symbols line up on any activated payline starting on reel one onward. For information purposes, this will be awarded on average, due to the reel layout, once every 63 spins.

Why not give the Bush Telegraph slot game a try and see if you can trigger those free spins within their expected trigger points? We have many Microgaming casinos for you to choose from. Come and take a look!

Twister Slot

If you're looking for a 20-line slot to play today, then how about giving the Twister slot some play time? This game does, of course, come with a special free spins bonus round. Like most other Microgaming slots, the bonus is triggered once you have spun in three or more of the Scatter  symbols in view on the base game screen.


You will be awarded with 20 free spins when the bonus game is awarded and all of those free spins will play out with 2x multipliers attached to them. You are going to find that when playing the Twister slot the bonus game trigger point in on average once every 94 spins.

Cash a Pillar Slot

Microgaming’s Cash a Pillar slot is one of their quite rare 100 payline slot games, and as such if you are looking for a large number of winning opportunities then this may just be a game to consider playing, three or more Scatter symbols will award you with some 15 free spins and any winning combination formed during that bonus round will pay out at three times its usual payout value as listed on the pay table.


Due to the number of Scatter symbols on each reel and the number of reel positions on each of its five reels the average trigger point for the free spins bonus round is on average once every 169 spins.

So be aware the free spins may not be awarded as often on this slot when compared to other Microgaming slots, however the winning payouts which can be awarded when playing all 100 paylines when the free spins bonus round is finally triggered can be quite sizeable.

You will have plenty of chances of triggering a free spins bonus round when you take advantage of our casino bonuses that will allow you to play plenty of additional spins with those bonus credits!

Harvey’s Slot

There is a very unique way in which you are going to trigger and be awarded the free spins when you are playing Microgaming’s Harvey’s slot game, and to do so you need to spin in a Scatter symbol on the second and fourth reels at the same time when playing off any single base game spin.

When the free spins are awarded to you then a random amount of free spins will be given to you which can number from six to thirty of them, plus a random multiplier will be awarded and attached to any winning combination that spins in during the free spins round, the multiplier values can range from x2 to x25.


The average trigger point for spinning in those two Scatter symbols together on the second and fourth reels is on average once every 127 spins. However due to the nature of the free spins bonus game and the random number of them awarded and the random multiplier values it would be advisable for you to activate all 25 paylines on each spin you play, to guarantee you the maximum winning opportunities when it triggers!

Halloweenies Slot

One of our featured Halloween themed slot games which is very unusual by virtue of it awarding you with 13 free spins on x3 multipliers when the free spins round is triggered is the Halloweenies slot. This is one of Microgaming’s 20 payline slots.


It should be noted that the average trigger point for the free spins to be awarded when playing this slot is on average 76 spins between each free spins feature, and as such you may stand a much better chance of being awarded the free spins round on this slot than you would when playing any other free spins awarding Microgaming slot!
