About this Slot
Puffer Stacks 2 is a sea-themed slot from Titan Gaming with an RTP of 96.37%, high volatility and a maximum win of 25,000x. The game uses six reels and nine rows with cluster pays mechanics.
Cascading symbols drop and respin after winning clusters form. Wilds substitute for paying symbols and act as both scatters and multipliers. During cascades, wild multipliers become sticky and influence follow-up drops.
Starfish symbols apply multipliers of 1x, 2x, 3x or 5x to all wilds on the grid, then transform into seashells. Fishnet symbols pull surrounding symbols together to create winning clusters when four or more seashells are present, then transform into the collected symbol to complete the win.
Bubble Catch triggers when three or more wilds land in a base spin, awarding two free spins per wild. The round uses only shellfish, wilds, starfish, fishnet and dead symbols. Bubble Catch retriggers when extra wilds land, adding two spins per wild.
Star Surge triggers with three wilds plus one starfish, using the same restricted symbol set. It awards two free spins per extra wild.
Shark Strike triggers with three wilds, one starfish and one shark head, using the same restricted symbol set and spin awards. During Shark Strike, all collected wild multipliers multiply together globally at the end of the feature.
Six buy options are available: Bonus Boost Mode at 2x bet, Bubble Catch Bonus Buy and Bubble Catch Battle Mode both at 100x bet, Star Surge Bonus Buy and Star Surge Battle Mode both at 400x bet, and Shark Strike Bonus Buy at 1,200x bet.
