Get ready to celebrate Dia de los Muertos (The Day of the Dead) in the Mexican style through the Skull Bonanza slot. Synot Games is often known to bring fruit-themed slot machines. However, now and then, it ventures into other themes resulting in epic slot games. Skull Bonanza is just that!

Synot Games has picked an unconventional theme to produce the Skull Bonanza slot. While we often see slots based on the Halloween theme, it is rare to find anything on Dia de los Muertos. This game was released on 03/03/2022 and has quite caught the punters' attention with its interesting features.

We have discussed all the details in our Skull Bonanza slot review further. Keep reading.

Skull Bonanza RTP and Volatility

7.4 
Skull Bonanza has an RTP of 96.14% and is a medium volatile slot.

An average RTP of 96% or above is generally considered ideal in the slot gaming industry. This rate ensures how much payout you will receive on your wins. The higher the rate, the better the payouts.

Furthermore, the medium variance gives an indication that the slot will feature a fair share of winning and dead spins. Also, the winnings will be reasonable.

Theme

8.2 

Skull Bonanza has the theme of the celebration of the Dia de los Muertos, which is The Day of the Dead in the Mexican region. The people of Mexico traditionally observe this day to remember their dead ones.

Synot Games has taken this theme to feature the celebration on the screen. You will find items that are used during this celebration in this game too. The developer has ensured high-quality graphics and animations. The background music is simple and soothing.

Skull Bonanza has different game symbols, which include 5 high-valued and 5 low-valued icons. The high-valued symbols are an Alcohol bottle, Aztec Marigold flowers, a basket of Fruits, and a Man and a Woman dressed for the occasion.

The symbols of man and woman are among the high-paying symbols in the game. The man symbol can offer a payout of 100x the stake for 5 of its symbols on the payline. The woman symbol gives a whopping 125x the bet for 5 symbols on the payline.

The low-valued icons are Ace, King, Queen, Jack, and 10. Furthermore, the special symbols include Wild and Scatter symbols. A color-changing skull is a Wild symbol featured on the slot. It substitutes for all symbols except the Scatter and brings you 1x, 5x, 25x, and 200x payout for 2, 3, 4, and 5 Wilds on reels, respectively.

Bonus Rounds & Free Spins

8 

Free Spins

Land 3 or more scatter symbols to activate the free spins feature. You get 10 free spins when the Scatter symbols land. The scatter symbols present a payout, too, along with the free spins. You can earn 5x to 1,000x the bet for 3 to 5 Scatter symbols.

When the free spin rounds begin, all the Wild symbols turn into Sticky Wild symbols. So, whenever these symbols land, they remain in place during the entire free spin rounds.

You get 2 kinds of Sticky Wild symbols:

  1. Sticky Wild with a ‘+’ sign and a number 1, 2, or 3. These symbols reward players with 1 to 3 additional free spins. The number of free spins rewarded is dependent on the number the Sticky Wild symbols carry
  2. Sticky Wild with an ‘x’ sign and a number 2 or 3. Wherever these Sticky Wilds land, they multiply the winning payline by 2x or 3x during the free spin rounds.

Free spins cannot be retriggered during the free spin rounds with Scatter symbols.

Gamble Feature

You can double your winnings after each successful round by guessing whether the card is red or black. You can do so 10 times per one winning.
