A line game with outer-reel triggers

Habanero lists five reels, three rows and 17 lines on a 15-coin basis, with High volatility. Pot of Gold symbols on reel one or reel five trigger the Expanding Wild feature on the center reel. If both reels one and five trigger, the effect expands all three center reels. The rule therefore makes feature coverage depend on which outer reels contribute; one side produces a single center expansion, while both sides produce the broader version.

This is a line-based layout, and the provider specifically adds bidirectional line wins during Expanding Wild. That means the feature changes not only which reels are covered by Wilds, but also the direction in which paylines can be evaluated. The source does not specify whether each line is counted once if it wins from both directions, or how overlapping combinations are handled. The in-game rules remain necessary for those accounting details.

Feature length and purchase option

The official overview lists up to 133 Free Games and a Buy Feature option. It does not provide the exact number or arrangement of Pot of Gold symbols required, the Free Games award schedule, or retrigger rules. The 133 figure is a maximum, not a normal bonus length. Buy Feature is an available mode, but the observation does not state its price or whether it changes the feature’s trigger configuration; no cost or probability is assumed.

The conditional pattern is the most useful part of the feature description: either outer reel is associated with an expanding Wild on the center reel, while both sides together expand all three center reels. Once active, bidirectional line pays add another evaluation direction. These rules allow a player to understand why different trigger placements can lead to different board coverage, but not how frequently either configuration appears. High volatility makes those unstated odds important to expectations.

Selectable RTP and limitations

Habanero lists High volatility, RTP options of approximately 86%, 92%, 94%, 97% and 98%, and a maximum multiplier of x2,031. Confirm the active RTP in the operator’s game information. The maximum is an upper bound rather than a typical result. The feature’s stated 133-Free-Game limit likewise says nothing about the award most players will see. No exact release date appears in the observed overview.

The leprechaun and pot-of-gold artwork support the Fantasy theme used for this review. Mechanically, the game is most distinctive when outer-reel positions determine whether one or all center reels expand. The trade-off is incomplete probability and pay-evaluation detail: the overview describes the special direction rule but not its edge cases. Players who prefer a fully specified feature sequence will need to consult the live paytable and rules.

Strengths and weak points

Strengths

The two outer triggers create a clear coverage distinction, and bidirectional line wins make the feature alter both Wild placement and evaluation direction.

Weaknesses

Trigger counts, award schedule and two-direction line accounting are unstated, while High volatility and a large ceiling do not resolve those uncertainties.

Our Editor’s View

Rainbowmania’s outer-reel triggers determine whether one or all three center reels expand, and the feature pays lines in both directions. The overview omits trigger counts, awards and opposite-direction accounting. Check local rules and RTP; 133 Free Games and x2,031 are ceilings, not typical outcomes. The layout’s changing coverage is a distinct hook, but the missing award details make the bonus harder to assess beforehand.
