About this Slot
Otter River Riches is a nature-themed slot from Adora Gaming with an RTP of 95%, medium volatility and a maximum win of 10,000x.
The wild symbol substitutes for other symbols and carries a multiplier value. When multiple wilds land on a winning line, their multipliers add together to boost the payout.
Three scatters trigger the River Riches bonus round. During River Riches, all wilds become sticky and remain on the board for the duration of the feature. Both Pebble Toss and Golden Pebble symbols land during this round. The Pebble Toss symbol boosts one random wild by a multiplier of 2x to 5x. The Golden Pebble symbol boosts all wilds by a multiplier of 5x to 10x. Additional scatters landing during River Riches do not retrigger the feature.
Four scatters trigger the Gold Rush bonus round instead. During Gold Rush, wilds become sticky and remain on the board for the entire round. Only the Golden Pebble symbol lands in this feature, boosting all wilds by 5x to 10x. Retriggers are not possible during Gold Rush.
The Spin Count Wheel awards 6, 8, 10, 15 or 20 free spins when triggered.
The Lucky Spins bonus buy increases the probability of landing River Riches and changes the multiplier applied each spin until it is turned off.
The River Riches buy starts the feature immediately with sticky wilds, Pebble Toss and Golden Pebble active, and applies the Spin Count Wheel to determine the starting spin total.
The Gold Rush buy jumps directly into the feature with the Spin Count Wheel setting the spin total, and only Golden Pebble symbols land.
The Pebble Toss buy guarantees the Pebble Toss symbol lands on every spin.
The Golden Pebble buy guarantees the Golden Pebble symbol lands on every spin.
