Online slot games with a retrigger feature.
Book of Ra
What exactly is a retrigger?
A retrigger, also known as a renewed trigger, is an online slot feature that can bring additional free spins to the player during a bonus round. Typically, such a retrigger is possible in the same way as the original free spins were triggered. So, if the bonus round can be initiated by three scatter symbols, then a retrigger occurs when another set of three scatters land on the reels.
How does the retrigger feature work?
This is how you can trigger a retrigger.
Unfortunately, you have no control over triggering a retrigger. However, the occurrence of these symbols works in the same way for most slot machines. Typically, you'll get a retrigger in the same manner you entered the free spin round. In most slots, this is triggered when at least three scatter symbols appear. Occasionally, there are also special free spin symbols that serve the same purpose.
Some providers, however, have implemented the retrigger feature differently and give you an additional free spin for every wild symbol that generates a win - this is the case, for example, in Merkur's Eye of Horus. Another variation is that within the free spin round, only two scatters are required to trigger more free spins. Furthermore, there are various other options available.
Unlimited retriggers, unlimited free spins.
While some slot machines have a limit on free spins, many slots have no restrictions on retriggers. With a stroke of luck, you can often trigger an indefinite number of retriggers. This means that theoretically, you can win an unlimited number of free spins. This gives you the opportunity to earn substantial winnings without having to place a bet.
