FAQ
What is the difference between the regular version of 3 Porky Banks and Extra?
The Extra version includes an improved coloured coin system, more paylines (30 instead of 25), additional bonus features, and a modified paytable. The RTP in the Extra version is also slightly higher – 95.13% compared to the base 93.10%.
How do the coloured coins work in the Hold & Win bonus?
Each colour has a unique function: blue coins double all coin values, red coins collect all visible values, purple coins transform into jackpots or large multipliers, and rainbow coins randomly transform into any other colour.
Which version of the slot has the best RTP?
3 Porky Banks Hold & Win has the highest RTP of 95.25%, followed by the Extra version with 95.13%. The Hold & Win Extra version offers 95.00%, which is still a good figure for a highly volatile slot.
What is Coin Shower and how often is it activated?
Coin Shower is a random feature that can activate at any point during the base game, adding exactly 6 coins to the reels and automatically triggering the Hold & Win bonus. The activation frequency is approximately once every 200-300 spins.
Is it possible to win all four jackpots in a single bonus round?
Theoretically yes, but practically it's highly unlikely. The Mini, Minor, and Major jackpots are won via purple coins, while the Mega is won by filling the entire grid. Winning all four would require exceptional luck.
How often does the Hold & Win bonus trigger?
On average, the Hold & Win bonus activates every 80-120 spins, which equates to a frequency of approximately 0.8-1.2%. However, due to high volatility, actual intervals can vary significantly.
What is the optimal bet for playing a highly volatile slot?
It is recommended to use bets of no more than 1-2% of your total bankroll. For example, with a €500 bankroll, the optimal bet would be €5-€10 per spin. This will allow you to withstand periods without major wins.
Is there a bonus buy option in 3 Porky Banks?
The bonus buy feature is not available in all jurisdictions and depends on local regulation. In some versions of the game, you can purchase direct access to the Hold & Win bonus for a specific amount, typically 100x your current bet.
Does the slot work on mobile devices?
Yes, 3 Porky Banks Hold and Win Extra is fully optimised for mobile devices. The game uses HTML5 technology and works on all modern smartphones and tablets without loss of functionality or graphics quality.
