Piggy Bank Farm slot by PlaynGo is a 5 reel, 4 row video slot, with 50 paylines. If you land the Hammer symbol on reel 5 it will trigger the Piggy Bank Spins feature and 3 spins are awarded initially, with only Piggy Banks landing.
Piggy Banks are then held sticky and can merge into mega symbols from clusters of 2x2, 3x3, 4x4 and 5x4. The feature begins with 3 lives and a life is lost when a spin does not land any new Piggy Banks. Piggy Bank Spins continue until all lives are used up and all "prizes" inside the Piggy Banks are revealed at the end of the Piggy Bank Spins.
If you on the other hand land a Scatter on reels 1, 3, and 5 it will trigger the Free Spins. 8 Free Spins are awarded, with the possibility to re-trigger within the free spins.
In Free Spins, Hammers can land anywhere on the reels to trigger Piggy Bank Spins. Multiple Hammers on the reels will apply a Multiplier of up to x10 to the Piggy Bank Spins’ total winnings. The 5x4, full screen Mega Piggy Bank awards up to 5000x total bet depending on the Multiplier on the feature trigger.
In this game it's all about maxing out the piggy banks, as the name cleary states – Piggy Bank Farm.
