About this Slot
Bull Rock is a music and nature-themed slot from Ferista Studio with an RTP of 92.1%, high volatility and a maximum win of 15,000x. The game uses 5 reels, 4 rows and 20 paylines.
Dancing Fish lands on any base spin or activates on every spin, hopping between 3 and 15 times to convert symbols into wilds. The feature skips bonus and wild symbols during its hops.
Bass Drop activates after any line win, replacing between 1 and 20 symbols on the board. Each replaced symbol carries a coin value ranging from 1x to 500x bet, which stacks with the original line win.
The Bonus Game triggers when 3 bonus symbols land and awards 6 free spins on a 5 by 7 board. The top 2 rows of the board are locked at the start. Keys that land during the bonus unlock locked cells; every 3 keys collected upgrade a premium symbol to wild and add 2 extra spins.
Raid Bonus triggers when 3 bonus symbols land alongside 1 raid symbol, awarding 8 raid spins on a 5 by 7 board. The top row starts locked and keys unlock cells. Every 3 keys collected upgrade a premium symbol to wild.
Super Bonus triggers when 4 bonus symbols land, awarding 10 spins on a fully open 5 by 7 board from the first spin. Every 3 keys collected upgrade a premium symbol to wild and add 2 extra spins.
Three bonus buy options skip the base game and trigger the bonus rounds directly. Bonus Game costs 100x bet, Raid Bonus costs 250x bet and Super Bonus costs 500x bet.
