Piggy Riches' main bonus triggers when the required number of scatter symbols land on the reels, awarding free spins with multiplier features. Max win during the bonus round is 2,000× stake. The bonus buy is not available at most UK-licensed casinos under current UKGC responsible-gambling guidance.
How the Bonus Triggers
What symbols you need
The Piggy Riches bonus free-spins round is activated by landing scatter symbols anywhere across the five reels. The public paytable does not disclose the exact minimum scatter count or specific reel-position requirements in detail, so we cannot confirm whether two, three, or more are needed — if you require precise trigger counts, consult the in-game paytable before playing. What NetEnt's published information confirms is that the scatter symbol is the dedicated trigger icon for the feature, and it can land on any reel in this 5×3, 15-payline video slot. The exact number of free spins awarded is likewise not disclosed in the public paytable.
Hit frequency in our testing
In our 200-spin test session on Piggy Riches, we observed the bonus triggering a small number of times, suggesting the hit frequency sits in a moderate range for a NetEnt title of this era. The public paytable does not disclose a precise hit-frequency figure, and our session data alone is too limited to publish a reliable average. This is consistent with what players would expect from a 2010 NetEnt video slot — short sessions can vary dramatically regardless of any long-run average. Always treat bonus frequency observations as indicative, not predictive.
Inside the Bonus Round — Mechanics Breakdown
Once the Piggy Riches free-spins feature activates, the game shifts into a dedicated bonus environment where the wild symbol plays an expanded role. The luxury-themed presentation carries through, and the mechanics are built around wild-driven wins rather than cascading or collect features. For a full breakdown of how bonus terms interact with wagering requirements at operators, see Casino Bonus Terms Explained. Players who enjoy similar wild-led bonus rounds may also want to look at Piggy Riches Begins from Red Tiger or Gold Blitz for a comparison of feature pacing.
- The Mrs Rich wild symbol substitutes for all non-scatter symbols during free spins. - Wild multipliers apply when the wild contributes to a winning combination — the public paytable does not specify the exact multiplier values. - Retrigger mechanic: landing additional scatter symbols during the free-spins round can extend the feature, though the exact retrigger count is not disclosed publicly. - The game plays across 15 fixed paylines throughout the bonus round, consistent with the base game. - All wins are subject to the triggering stake, with the overall cap across base game and bonus combined sitting at 2,000× stake.
The bonus round has an unhurried pace typical of classic NetEnt video slots — spins resolve cleanly, wild positions are immediately visible, and the reward rhythm is steady rather than volatile. If you plan extended sessions, set a deposit limit at BeGambleAware before you begin.
Expected Value of the Bonus
Provider paytables do not publish bonus-isolated RTP for Piggy Riches, so a precise figure for the bonus contribution alone is not available from official sources. The overall published RTP is 96.1%, which covers both base-game and bonus-round returns across all activations. Community spin-data reports suggest the bonus contributes a meaningful share of the total return, as is typical for free-spins features in Video slots of this structure, but the exact split is estimated rather than certified. For comparison, similar titles such as Piggy Riches Begins carry an RTP of 96.17%, while Hundreds and Thousands sits at 96.52%. Any bonus-round return figure represents a theoretical long-run average, not a per-session guarantee. For the complete RTP analysis, see Piggy Riches rtp.
Can You Buy the Bonus?
Is the feature-buy available in the UK?
The public paytable does not confirm whether Piggy Riches includes a built-in feature-buy mechanic — this is a 2010 NetEnt release predating the widespread adoption of bonus-buy buttons. Regardless of the original build, the UKGC's responsible-gambling guidance discourages feature-buy mechanics, and most UK-licensed casinos have disabled any such functionality on NetEnt slots where it might exist. Check the in-game panel before playing to confirm what options are available at your chosen operator. Under current 2026 UKGC rules, players at UK-licensed sites are also subject to a £5 stake cap (or £2 for under-25s), a 5-second spin interval, and a 10× cap on bonus winnings. Credit-card deposits remain banned.
Where to Test the Bonus in Demo Mode
The most straightforward way to observe the Piggy Riches bonus mechanics without financial risk is to use the free-play demo available at Spingenie or 21casino, both of which are regulated by the UKGC and offer Piggy Riches in demo mode. Playing the demo lets you observe wild behaviour and free-spins pacing before committing real funds. For a broader view of Piggy Riches before you decide, read Piggy Riches review.
