Skull Bonanza Features

In Skull Bonanza, the main feature is the Free Spins that are triggered by landing 3 or more scatter symbols. 10 free spins will be awarded and all wild symbols change into sticky wild symbols. These sticky wild symbols land on the reels and remain in place for the duration of the feature.

There are two types of sticky wilds with the first having an addition sign '+' and a number between 1 to 3 to award additional free spins. The second type of sticky wild includes symbols with an 'x' symbol with x2 or x3 leading multipliers for the rest of free spins.

Alongside these, there is the option to gamble during free spins to double your win. All you need to do is guess the colour of the next revealed card to double - but there is the chance to lose your win completely.

Skull Bonanza Review

Originated in Mexico, Day of the Dead is a special holiday held from 1st November until the 2nd with revellers paying offerings to lost loved ones.

SYNOT Games decided that players should have the chance to celebrate this all year long with Skull Bonanza. Playing on 5-reels with 9 paylines, this medium volatility Mexican slot features a whole host of features.

Fans of free spins will absolutely love this game as there are multipliers, additional spins and sticky wilds leading to epic wins reaching up to 10,000x your stake.


As the slot opens up, you'll be greeted to a screen in Mexico with beautiful flower petals falling in the wind along with some scattered on the floor. In the distance, there are colourful and stunning buildings highlighting the wonder of the Day of the Dead.

In free spins, you are taken into a graveyard to pay your respects and honour the dead. There are various tombstones and sugar skulls guiding you throughout this mode.

As for symbols, all the wilds have vibrant sugar skulls on them with different expressions. There is an enchanting woman adorned in Day of the Dead attire followed by a mariachi man dressed similarly. It all fits in well to transport you to the special event.

Thankfully, the music is a soft mariachi score playing throughout which feels fitting for this slot. This intensifies when you are about to trigger a special feature to build up the atmosphere even more.


The base game for Skull Bonanza is quite standard, but it intensifies during the free spins round. Here, you'll find sticky wilds, multipliers and additional spins improving your gameplay.

At the bottom of the screen, you'll find the spin button, bet level and additional settings in case you need them.

Win Potential

The RTP ranges between 85.10% to 97.97% in different jurisdictions but the default is 96.14% which is a respectable amount. Alongside this, there's a hit rate of 23.79% that is pretty standard for online slots.

As for the volatility, Skull Bonanza has a medium volatility level leading to a mixture of high and low volatility gameplay. Finally, the maximum win is a fantastic 10,000x your stake that can be achieved throughout the free spins round.

Our Verdict

After absolutely loving Zeus Wild Thunder, we had high expectations for Skull Bonanza and thankfully it managed to live up to the hype. The base game is quite simple, but the free spins round completely changes the gameplay.

In addition to the gameplay providing thrills, the overall presentation of the design is absolutely stunning. This added with the win potential makes Skull Bonanza an absolutely classic from SYNOT Games that you should not miss out on.
