In order to start the bonus round, all you need to do is get three or more scatter symbols on any reel position.

This choice will reveal a multiplier value that will be used to multiply any winnings earned during the free spins. The available multiplier options include 20x, 25x, 30x, 50x, and 100x.
Once the pick ’em round is completed, the free spins will begin and continue until your winnings surpass the multiplier value.

Moreover, the free spins include sticky wild symbols that remain in place for the entire bonus round. In conclusion, the free spins offered by Big Bonus are an exciting feature that guarantees a payout greater than the multiplier value.

How bonus games and free spins works

In order to enhance your gaming experience, it is crucial to activate a bonus feature prior to playing. The process of unlocking the bonus game may differ depending on the slot game. Additionally, each bonus round functions in a distinct manner. Some offer free spins, while others transport you to a pick ’em screen, akin to the popular game Lobstermania.
This is a concise depiction of how a bonus round might operate within a slot machine:
- As soon as three scatter symbols appear on the reels, the bonus is activated, granting players 10 free spins accompanied by expanding wilds and win multipliers. These win multipliers have the potential to increase the overall payout of each spin by a maximum of 100 times. During one of these free spins, you successfully secure a prize that is 120 times the value of your initial bet. Once the bonus round concludes, the 120x payout will be promptly added to your bankroll.
How to trigger the bonus games online
As mentioned earlier, there are multiple ways to activate bonuses in each slot. The most common method is when three scatter symbols appear anywhere on the reels. Furthermore, if you come across more triggering scatters, you have the chance to receive an improved bonus. Additionally, there are a few alternative methods to trigger bonuses:
- Scatter symbols must be dispersed in specific reels or positions. For example, a game might require scatter symbols to land simultaneously on both reel one and reel five.
- In specific real money slot games, players need to collect symbols in order to activate a bonus or a minor feature, like expanding wilds, when they gather a sufficient number of symbols.
- In an unpredictable fashion, specific games possess the ability to trigger a bonus round, lacking any discernible pattern. For instance, in an online slot game, the bonus feature may be activated roughly once every 200 spins, on average.
- Introducing the feature buy: Nowadays, more and more slot developers are providing players with the option to buy the bonus round. As an example, you might be given the chance to obtain the feature by paying 100 times the stake. Once bought, the bonus will immediately activate on the next spin.
