Underworld Features & Bonus Games

This exciting slot from Titan Gaming comes with a range of thrilling features, including a multiplier ladder and symbol upgrades.

Multipliers

Multiplier symbols can land on the grid or be spawned from Hades randomly. The multipliers get applied to the total tumble win at the end of the tumbling sequence or spin.

The multipliers come in 4 tiers:

• Blue Multipliers: 2x – 8x

• Green Multipliers: 10x – 25x

• Purple Multipliers: 50x

• Red Multipliers: 100x – 500x

Symbol Upgrade

During the game, Hades triggers his blue ability and randomly transforms a low-winning symbol into a superior symbol.

Add multipliers

Hades can trigger his green ability randomly during the game to spawn multipliers ranging from 2x to 500x.

Double multipliers

During the game, Hades can trigger the red ability, and double random multipliers can be present before being applied to a tumble win.

Global multiplier

During the game, a global multiplier is present next to the grid. This multiplier can be enhanced by landing multiplier symbols on the grid. However, the multiplier symbols come into effect only if a win tumble takes place.

Bonus

There is no wild symbol, but the slot does come with a scatter symbol. Hades’ chair is the scatter symbol of the slot. It can appear on all reels, and if 4 lands on the reels in a single spin sequence then the bonus is triggered, and you receive 15 free spins.

Bonus Battle Feature

The Bonus Battle is a fun game mechanic where you can face off against Billy the Bully in a winner takes all challenge. After buying into the battle, you can choose one of two slot options, and Billy will get the other. Then, you and Billy will take spins in your bonus rounds and aim for the highest win. If your winnings in the bonus round are higher than Billy’s, then you win the total combined for both your rounds. And if there is a tie-breaker, you automatically receive the total combined winnings.

Feature Spins Option

The slot comes with three bonus spin options where you can choose which feature you want to activate. The feature and your bet size determine the cost of the feature.

• Bonus Boost – Activate a double chance of triggering the Bonus Round (1.2x)

• Bonus – Enter the bonus with 15 free spins (100x)

• Bonus Battle – Battle against Billy in the Bonus (100x)

Max Win & Return to Player (RTP)

Before you hit the spin button on Underworld, you can set your amount to between 0.10 and 100.00 per game round. A random number generator (RNG) is used to ensure the outcome remains fair in the base game and special features.

The slot offers a highly volatile online gaming experience with a return to player percentage (RTP) of 96.34%. Throughout the base game, the max win is at 10,000x, but during the bonus free spins, you can walk away with maximum wins of 20,000 times your play amount.
