A focus on symbol changes and bonus modes

Two roles are especially well represented here: symbol changes and bonus modes. The wild family brings combination-forming mechanics into the mix. Free-spin mechanics form part of the bonus-play structure.

The game pairs its core format with a medium-sized collection of special mechanics, adding several distinct elements to the overall structure.

Highlight Features

Retrigger

A Retrigger means winning additional free spins by landing scatter symbols again during a free spins bonus round. Furthermore, some slots adopt an 'unlimited retrigger' system, which means there is no limit to the number of times it can re-trigger. In theory, if luck is on your side, the free spins can continue indefinitely, making it one of the most powerful features a slot can have.

Sticky Wild

A Sticky Wild is a special wild symbol that, true to its name, does not disappear immediately after appearing on the reels. Instead, it 'sticks' in place and remains there for multiple subsequent spins. This feature shows its true potential primarily during free spins bonus rounds, making it a powerful system that can grant massive rewards by progressively making the game board more advantageous for the player.

Bonus Buy Efficiency

Average Bonus Buy Price

This slot's bonus buy price sits within the usual range for comparable slots. Buying the feature can be a reasonable option if your goal is to reach the free-spin round without waiting for a natural trigger. The trade-off is that you skip the base-game spins that would normally happen before the feature, including any wins or volatility from that part of play.
