There are 11 symbols, including four low-paying card symbols from J to A and five premium character symbols represented by different coloured backgrounds. The game also includes Wild and Cash Coin symbols. The green premium character is the highest-paying regular symbol, awarding up to 4x the stake for five matching symbols.

Wilds substitute for other symbols to complete winning combinations and can also form their own winning combinations when appearing within a pay line. Wilds are available during the Base Game but cannot substitute for Overlay Tokens.

Immortal Romance Assembl’em Features & Mechanics

Overlay Tokens

Overlay Tokens are exclusive to the Base Game and appear over existing symbols on the reels. When collected, they are removed to reveal the symbol underneath. Each Overlay Token corresponds to one of the Feature Cards available in the Assembl’em feature and can only appear when its associated Feature Card is active. Overlay Tokens do not have a direct pay out.

Assembl’em Feature

The Assembl’em feature determines which options are available during the ULTRA Link&Win feature. Up to five Feature Cards can be unlocked and upgraded, with each card occupying its own position.

Feature Cards and their positions are unlocked progressively by meeting specific requirements displayed during the Base Game. Only unlocked cards positioned in unlocked positions are active, and players can customise which unlocked Feature Cards are active.

Base Game spins contribute towards unlocking Feature Cards and the first three card positions. The fourth position becomes available once all five Feature Cards have reached Gold or higher, while the fifth position unlocks once all five cards reach Diamond.

Feature Card Upgrades

Feature Cards can be upgraded from Ruby to Gold and then from Gold to Diamond. Once achieved, upgrades remain active and do not reset.

Upgrades can be awarded randomly after completing the ULTRA Link&Win feature or following a 24-hour countdown. Purchased ULTRA Link&Win features do not normally award random upgrades, although an upgrade can be awarded when the feature is purchased before the first Base Game spin.

Only one Feature Card can normally be upgraded at a time, although it is possible for two cards to upgrade simultaneously in rare circumstances.

The Adder card determines which Adder Booster Coins can appear:

  • Gold: Up to 3 Semi-Persistent Adder Booster Coins
  • Diamond: 1 Persistent Adder Booster Coin

The ULTRA Link&Win feature can trigger when one or more Overlay Tokens are collected. Depending on the active Feature Cards and triggering tokens, between one and five additional features can be active.

The feature begins with three free respins. Only Coin symbols can land, while all other positions remain blank. Any Coin that lands is held in place and resets the respin counter to three, while blank positions respin.

The feature ends when all respins have been used or when the entire grid is filled.

Cash Coins

Cash Coin values are multiplied by the total bet and can range from 0.2x to 10x. Cash Coins are awarded when the ULTRA Link&Win feature ends.

Jackpot Coins

The available Jackpot Coins are influenced by the active Feature Cards. Starting values are:

  • Mega: 2,500x
  • Maxi: 500x
  • Minor: 50x
  • Mini: 15x

Jackpot values are multiplied by the total bet. Each Jackpot Coin has a countdown that decreases once per spin. Any Jackpot Coin that completes its countdown before the feature ends is awarded when the feature concludes.

Booster Coins

Booster Coins provide additional modifiers during ULTRA Link&Win.

Cash Collect Booster: Collects the combined value of eligible Cash Coins and Adder Booster Coins for the current spin.

Semi-Persistent Cash Collect: Remains active for three consecutive spins and collects eligible values during each spin.

Persistent Cash Collect: Retriggers on every spin and continues collecting eligible values until the feature ends.

Cash Collect features cannot collect Mini, Minor, Maxi or Mega Jackpots.

Multiplier Boosters

The 2x Multiplier Booster can randomly double up to four Cash Coins during the current spin, while the 3x Multiplier Booster can triple up to four Cash Coins.

The Persistent 2x Multiplier Booster repeats this effect on every spin until the feature ends.

Jackpots and other Booster Coins cannot be affected by these multiplier features.

Adder Boosters

Adder Booster Coins add their displayed value to eligible Cash Coins during the current spin.

The Semi-Persistent Adder remains active for three consecutive spins, while the Persistent Adder continues to apply its value on every spin until the feature ends.

Adder values range from 0.2x to 10x the bet. Adder Boosters cannot increase Jackpot values or the value of Cash Collect Booster Coins.

General Feature Rules

The ULTRA Link&Win feature can be triggered during the Base Game, with the feature played at the same bet that triggered it. Any winning combination that occurs on the triggering spin is paid before the feature begins.

Wins generated during ULTRA Link&Win are added to the Base Game winnings. Jackpot and Booster Coins are not guaranteed to appear, even when their associated Feature Cards are active.

Upsizer Feature

After triggering ULTRA Link&Win, players may be offered an option to purchase an enhanced version of the feature. The available options depend on the active Feature Cards and their upgrade levels.

The purchase must be confirmed before ULTRA Link&Win begins, with the applicable price displayed before purchase. Availability can vary depending on bet level and region.

Buy Feature

The Buy Feature is available in the Base Game and instantly triggers ULTRA Link&Win. The available purchase options and their costs depend on the active Feature Cards and their upgrade levels.

The Buy Feature does not contribute towards Feature Card upgrades and is played at the current bet. Availability may be restricted at higher bet levels or in certain regions.
