Zitro launches Clover Paddy slots with expanding reels and five jackpots

Zitro has detailed the mechanics and feature set of Clover Paddy, an Irish-themed slot game family developed for its CONCEPT cabinet, and promoted the series at Global Gaming Expo (G2E) in Las Vegas, Nevada earlier this month. The family comprises two titles, Gleann and Lough, and centres on a leprechaun character whose interventions add wild symbols, boost prizes and advance players toward the bonus rounds.

Clover Paddy slot family and where it sits in Zitro's portfolio

Clover Paddy is built for the CONCEPT cabinet and released as a two-title family made up of Gleann and Lough. Zitro presented the series at G2E in Las Vegas, Nevada, as part of its broader showcase of CONCEPT cabinet content. The games follow a thematic line rooted in Irish motifs and place a leprechaun figure at the centre of the player experience.

The supplier positions the two titles as variations on the same core mechanics: both use the same leprechaun-driven feature set and progressive structures, with differences in audiovisual treatment and paytable tuning between Gleann and Lough.

Core features: Increase, Jackpots and Multiplier

Zitro highlighted three named features that can combine during gameplay: Increase, Jackpots and Multiplier. These operate in both the base game and the bonus round and interact through coin accumulation and mystery events.

• Increase: Symbols that can be reactivated during mystery events in the bonus round and that expand the reel grid to create a larger playfield.

• Jackpots: A mechanism that fills a row with heart symbols during bonus events to collect one of the progressive prizes.

• Multiplier: A function that can multiply wins by up to five times when triggered in the bonus round.

During base-game spins the leprechaun can either scatter wild symbols across the reels or place a large three-by-three wild block across the central reels. Coin symbols appearing on the reels contribute to feature accumulators; activation of one or more of the named features unlocks the bonus round.

Bonus round: expanding reels, mystery hat events and Rainbow Roulette

When the bonus round is triggered the reels expand into a five-by-five grid, changing the geometry of the game and creating additional lines for win evaluation. In the bonus, the leprechaun’s hat can trigger mystery events with three possible outcomes described by Zitro:

• reactivation of Increase symbols already present on the grid;

• application of the Multiplier, increasing wins by up to five times;

• filling a row with heart symbols to collect one of the game's jackpots.

Separately, landing a Rainbow symbol during play opens a distinct Rainbow Roulette bonus round. That bonus round operates with its own progressive jackpot pathway, independent from the main five-jackpot structure.

Five progressive jackpots and their names

Zitro says Clover Paddy offers five jackpots available to players: Mega, Rainbow, Sapphire, Emerald and Amber. The Rainbow jackpot is tied to the Rainbow Roulette bonus round, while the other named jackpots are collectible through heart-row fills and jackpot-related features during the main bonus.

The supplier’s description makes clear that jackpots and feature multipliers can be active at the same time, allowing for combined prize events when the bonus round and mystery events align.

How features combine during the base game and bonus

The game flow relies on coin symbols in the base game to charge accumulators that unlock the bonus. The leprechaun acts as the in-game catalyst: in the base game it scatters wilds or places a three-by-three wild on the centre reels, and it can award additional coins to accelerate progress towards the bonus. Once the bonus round begins, the same character’s hat is the trigger point for mystery events that can expand or reactivate Increase symbols, apply multipliers up to 5x, or create the jackpot-collecting heart rows.

Because the three named mechanics are described as combinable, operators can expect moments where expanded reels, active multipliers and jackpot-collecting rows coincide within a single bonus sequence.

Trade and venue context

Zitro first showcased Clover Paddy among its CONCEPT cabinet lineup at Global Gaming Expo (G2E) in Las Vegas, Nevada earlier this month. The appearance at G2E situates the titles within the supplier’s international commercial push for CONCEPT cabinet content and signals the supplier is marketing the family to land-based casino operators that deploy that cabinet.

Operators and casino content buyers evaluating the family will focus on how the expanding 5x5 bonus geometry and stacked feature interactions affect hit frequency, volatility and floor-level jackpot contribution. For suppliers, the games continue a trend of combining expanding-reel mechanics with multiple progressive pools and on-grid big-symbol events.

What operators should note about deployment

Deployment on the CONCEPT cabinet means operators using Zitro’s platform ecosystem can present Gleann and Lough with the cabinet’s hardware features and configuration options. The titles share a single design template: the same leprechaun-driven feature set, the same five-jackpot structure and the Rainbow Roulette bonus, with differences limited to aesthetic and paytable tuning between the two releases.

Operators considering the family will want technical briefs that detail jackpot funding mechanics, progressive contribution rates and the conditions that unlock the Rainbow Roulette bonus. Zitro’s public materials name the five jackpots and the in-game triggers but do not publish contribution percentages or hit-rate statistics in the announcement.

Summary

Clover Paddy is a two-title slot family from Zitro for the CONCEPT cabinet that uses a leprechaun character to drive base-game wilds, coin accumulation and bonus access. The bonus expands the reels to a five-by-five grid, offers mystery hat events that can reactivate Increase symbols or apply multipliers up to five times, and provides mechanisms for collecting one of five jackpots: Mega, Rainbow, Sapphire, Emerald and Amber. Zitro promoted the series at Global Gaming Expo in Las Vegas earlier this month, positioning Gleann and Lough for operators seeking expanding-reel mechanics combined with multiple progressive jackpots.
