Paylines
40 paylines (left-to-right + top-to-bottom)
Forty paylines on a 3×3 grid sounds wrong on paper. The trick Piggy Bank pulls is dual-direction evaluation: roughly half the lines pay left-to-right across the rows, the other half pay top-to-bottom down the columns. Win both ways, basically. Most YGR games stick strictly to left-to-right, so this is a structural break from the usual house style and the same winning combination can pay on both axes when symbols align right.
Three pig tiers run independently, each gating its own feature path. Yellow Piggies only land on five fixed positions – the four corners and the centre cell of the 3×3 grid. Three of them anywhere across those slots awards 7 free spins, four awards 10, and five maxes out at 15. Red Piggies land anywhere on the grid and behave differently: when one drops it locks in place and triggers a single respin, and each new Red Piggy landing during the respin chain resets the counter. Clustering reds into a chain is how the base-game potential builds. Then there are Piglets – scatter-equivalent baby pigs that combine with Yellow and Red on the overall pig count. Five or more pigs of any mixed type fires the Bonus Game.
The Bonus Game is where the design gets ambitious. Entry starts at 10 free spins on the base 9-cell grid. As more pigs land during the round, the grid physically expands, scaling up to a maximum of 54 cells spread across 6 mini-grids. Each new pig landing during the bonus also drops its multiplier value onto the 8 reel positions surrounding it, creating localised multiplier fields that stack as the round runs. GRAND, MAJOR, and MINOR jackpot Pigs appear during the bonus too, carrying fixed prize values (the banner at the top of base-game play previews $200 for the 9-Piggy GRAND at 0.20 stake). Those three jackpots don't multiply through the 8-reel bonus – they pay their stamped values flat.
An Any 4/5/6/7/8 ladder runs along the left rail during base play, escalating payouts for collecting any single colour of pigs, capping at $20 for Any 8 at base bet. Buy Bonus button gives direct entry to the 10-FS round. Symbol set is Chinese-prosperity heavy: red, green, blue, yellow, and orange money bags stamped with longevity characters, gold and silver ingots, deep red brocade backdrop with cloud patterns. Pig art is cartoon-round, pink snouts, gold coin-slot backs. Bet range runs 0.20 to 50.00. Honestly, the expanding grid alone is the kind of thing you'd expect from a high-budget Pragmatic Play title, not a YGR mid-list – the design ambition here is unusually high.
