Dr Unded’s Boo Balls Slot Features & Bonus Games

In Dr Unded’s Boo Balls, there is a plethora of bonus features and mechanics, including multiplier symbols, exploding titles, and more.

Cluster Pays

Wins are formed by connecting between 3 and 33 symbols anywhere on the grid, connected by any of the hexagon’s surfaces. Payouts are calculated by adding each symbol’s values together.

Cascading Symbols

When a winning cluster is paid out, the symbols will fall from the grid in a cascading reels mechanic, allowing new ones to fall into their place and create new wins.

Multiplier Symbols

Landing a multiplier symbol directly adjacent to any winning cluster multiplies the payout value. These symbols come in the values 2x, 3x, and 4x.

LLAMA Tiles

Landing 1 or more LLAMA wild symbol tiles next to a winning cluster triggers two bonus effects. First, every symbol matching the cluster becomes a LLAMA tile, even if they are not connected. Second, the total value of all of the tiles is doubled and paid out.

Destructive Tiles

There are a number of symbols that have no payout value, but can clear other symbols from the board. The Bluest Ball symbol burns the 2 symbols above it, allowing 2 more to fall into their place. The Dynamite symbol destroys all symbols connected to it, allowing more symbols to drop in.

Free Spins

Landing 3 or more free spin scatter symbols in a group triggers the same number of free spins as symbols collected.
