About this Slot
Bubble Reef Riches is a Fishing-themed slot from Colossus Studios with an RTP of 96.71%, medium volatility and a maximum win of 4,000x the bet.
Three Scatters landing on reels 1, 3 and 5 trigger Free Spins, awarding an initial 10 spins. During Free Spins, three Scatters appear again to retrigger the feature and add 10 more spins to the total.
Prize Fish appear randomly during Free Spins only, in three tiers with values ranging from 1x to 500x the bet. Each Prize Fish increases the global multiplier by 1. The global multiplier starts at 1x in the standard bonus and carries through all retriggers.
The Fisherman symbol appears during Free Spins only. When it lands, the Fisherman collects all visible Prize Fish on the reels and multiplies the collected total by the current global multiplier value.
Three bonus buy options are available from the menu. The Hunt option costs 2x the bet and provides direct access to the bonus feature. The Bonus option costs 100x the bet and begins Free Spins with a 1x global multiplier. The Super option costs 250x the bet and starts Free Spins with a 5x global multiplier that increases by 5 for each Prize Fish caught instead of 1.
