When Pigs Fly Overview

Hacksaw Gaming’s When Pigs Fly takes the popular Irish saying and turns it into a vibrant, cluster-paying slot adventure. The game is set against a dreamy sky filled with fluffy clouds, where a squadron of charming, helmet-clad pigs are ready to launch from their flying machines. The cartoonish art style is top-notch, full of colour and playful animations that bring the whimsical theme to life.

This isn't your standard reel setup. The game uses a 7x7 grid and wins are formed by landing clusters of 5 or more matching symbols horizontally or vertically. This mechanic, popularised by games like Sweet Bonanza, creates a dynamic and often explosive gameplay experience where one win can cascade into another.

The slot is squarely aimed at players who enjoy high-volatility action and the potential for big, chain-reaction wins. The "Piggy Meter" feature adds a layer of strategy and anticipation, as you watch your adorable aviators progress towards various bonus modes. It’s perfect for the Irish player who likes a bit of craic with their spins—a game that doesn’t take itself too seriously but packs a serious punch in the payout department.

Verdict: When Pigs Fly is a brilliantly executed, feature-packed slot from a top-tier provider. Its high volatility means patience can be required, but the engaging features, excellent max win potential, and utterly charming theme make it a standout title well worth a spin for those chasing that "when pigs fly" moment of a massive payout.

RTP, Volatility & Max Win

The Return to Player (RTP) for When Pigs Fly is a very competitive 96.27%. This figure is above the industry average and is a positive sign for players, indicating a solid theoretical return over an extended period of play. Always check the game rules at your chosen casino, as some operators may offer alternative RTP configurations.

This is unequivocally a high-volatility slot. In practice, this means wins may not land frequently, but when they do, they have the potential to be significant. Bankroll management is crucial here; you'll want a sufficient balance to weather the potential dry spells while waiting for the feature triggers and big cluster combinations that define the game's payout structure.

The ultimate prize is a whopping 10,000x your stake. This colossal max win is achieved through the game's bonus features, particularly during the free spins rounds where multipliers can stack and the grid can fill with high-value symbols. Hitting this figure is, true to the theme, a rare and spectacular event, but it's a target that gives the high-stakes action a clear and thrilling purpose.

Bonus Features & Free Spins

When Pigs Fly is loaded with creative features that drive the gameplay. The action centres around the Piggy Meter on the left side of the grid, which fills with every winning symbol that forms part of a cluster.

The Piggy Meter & Piggy Features

As you collect winning symbols, one of four pig aviators progresses up their ladder on the Piggy Meter. Reaching a pig at the top triggers one of four random Piggy Features: Swine Dive (adds 2-4 wilds), Piggy Puffs (transforms 2-3 symbol types into another), Piggy Pop (removes all low-paying symbols), or Piggy Flight (adds a 2x-10x multiplier wild). These features can turn a modest win into a much bigger one.

Piggy Bonus Round

Landing 3 bonus scatter symbols triggers the Piggy Bonus Round. You'll pick from pigs to reveal one of the four Piggy Features, which then plays out on the grid. The number of picks you get depends on the number of scatters: 3 scatters = 1 pick, 4 scatters = 2 picks, 5+ scatters = 3 picks. This round is a great way to get a direct injection of bonus action.

Free Spins (When Pigs Fly Bonus)

The main event is triggered by landing 4 or more bonus scatter symbols. You start with 10 free spins. The key here is that the Piggy Meter does not reset between spins. Any progress made during the base game carries in, and progress continues throughout the free spins. This allows you to trigger the Piggy Features much more frequently. Furthermore, landing additional scatters during the round awards +2 extra free spins. The potential for multiplier wilds and symbol transformations to compound during this mode is where the dream of the 10,000x max win truly takes flight.
