Puffer Stacks 2 Slot Features & Bonus Games

Puffer Stacks 2 is a game packed to the brim with exciting bonus rounds and features, including wild multiplier symbols and free spins.

Wild Symbol

The Wild symbol is a golden fisherman, and it substitutes for any winning symbol on the reels. It also acts as a scatter and multiplier, which becomes sticky when the reels cascade.

Starfish and Seashell Symbols

The Starfish is a multiplier that appears in both the base and bonus games. Landing one will apply a 1x, 2x, 3x, or 5x value to all Wilds on the reels at the same time. After that, it will transform into a Seashell symbol.

Seashells are instant wins. Forming a cluster of 5 or more Seashells sees you collect their wins of anything from 1x to 1000x. They come in three tiers, which are:

Bronze: 1x 2x 5x
Silver: 10x 25x 50x
Gold: 100x 250x 500x 1000x

Fishnet Symbol

The fishnet symbols catch symbols around them and bring them together to form a winning cluster. They can even attract Seashells if there are 4 or more on the grid. The Fishnet will then turn into the symbol it has collected to form a payout.

Bubble Catch and Star Surge

The Bubble Catch bonus is triggered by landing 3 or more Wild symbols during a single spin in the base game. The Star Surge bonus has the same rules as Bubble Catch, but is triggered by landing at least 3 Wilds and 1 Starfish.

You are given 2 free spins for every Wild on the reels, and landing more Wilds in the bonus will trigger 2 more free spins for every symbol. Only Shellfish, Wilds, Starfish, Fishnet, and Dead symbols can land in this bonus game.

Shark Strike

The Shark Strike bonus is the same as both the Bubble Catch and Star Surge rounds, except with one twist. At the end of the game, all the multipliers from the Wild symbols collected are multiplied together to form a global multiplier that is added to all wins.

This game can be triggered by landing at least 3 Wild symbols, 1 Starfish, and 1 Shark Head.

Bonus Feature Option

Titan Gaming offers a bonus feature spin mechanic unlike any other. The Bonus Battle is a unique approach to the feature, and it sees you come up against Billy the Bully.

There are a number of different options to choose from - from low to high volatility - and you can select a different battle type. You can also choose a normal bonus feature option, and you can do so with the following amounts:

Bonus Boost Mode: 2x Your Play
Bubble Catch Bonus Buy: 100x Your Play
Star Surge Bonus Buy: 400x Your Play
Shark Strike Bonus Buy: 1,200x Your Play
Bubble Catch Battle Mode: 100x Your Play
Star Surge Battle Mode: 400x Your Play
Shark Strike Battle Mode: 1,200x Your Play

Play Sizes, Max Win & Return to Player (RTP)

You can play Puffer Stacks 2 from as low as 0.10 all the way up to the maximum play of 1,000.00. Random number generator (RNG) technology ensures every round’s outcome is provably fair, including in the bonus rounds. If you’re looking for slots with low and high volatility available, this is one of those options. It has a volatility switch.
