What is a Retrigger on Slot Machines?

How does this exciting Retrigger mechanic work? Continue reading below to learn more about slot retriggers and how they can help you win more money.

  • Retrigger Feature
  • Retrigger Slots

Online Slots these days include a lot of features, including retriggers, that make them far different than the penny slots of old. Retriggers are usually available in bonuses and do what they say. They give players a chance to retrigger a bonus or feature, essentially prolonging their life in the slot game.

What Are Retriggers?

A slot retrigger is just what it says on the label – a way to retrigger a bonus or a special feature. This is almost always linked to free spins, where you trigger the bonus with three or more scatters. Hitting the same combination within the bonus round is a retrigger, giving you just as many spins as you’ve won the first time.

This special mechanic doesn’t work in all slots nor for all bonus rounds. Some slots have it, others don’t. Luckily, slots with retriggers outweigh the others.

How Does a Retrigger Work?

In most slots games, retriggers are simply a way to extend the bonus round. Why is this important? Because it keeps you alive for longer. For example, if you trigger a bonus round with 15 free spins, a retrigger with the same combination will give you 15 more.

The usual retrigger combination involves three scatters or bonus symbols. That combination gives you as many spins as the regular one. However, you can sometimes retrigger a bonus with more free spins if you’re lucky to land more scatters than the original combination. That requires for the slot to recognize such combo, as some only trigger bonuses with three scatters.

Some slots have a higher predisposition for retriggers. For example, a slot might offer retriggers for hitting two bonus or scatter symbols during the bonus. This makes it much easier to hit a retriggering combination for which you’ll rack up extra spins.

Respins retriggers are also possible under certain conditions. In most cases, a win will retrigger a respin which can go on indefinitely depending on how lucky you are.


It depends on the developer. In most cases, retriggers are only available for and within free spins rounds. Sometimes, you can also retrigger another special feature such as a respin.

No, they aren’t. This feature is slot-dependent, meaning some slots have it, and others forbid retriggers.

Absolutely – that’s the reason developers enable retriggers. By earning more free spins during the bonus round, you’re essentially getting more ways to win.

Yes, they are. For example, some slots will allow retriggers with a single or two bonus symbols instead of the typical three. In this case, you will hit retriggers easier.

Yes, they can, but the number of extra spins you can get is usually capped. Some will keep it to something like 50 in a row, others will allow you to earn several hundred.
