About this Slot
Boss Raid! is an action and adventure fantasy slot set in a medieval world on a 7x7 grid with Cluster Pays. The game offers an RTP of 96.4%, high volatility and a maximum win of 5,000x.
Matching symbols must connect orthogonally to form clusters. When five or more matching symbols land, they explode and cascade, with subsequent cascades increasing a multiplier that rises through x2, x3, x5 and x8.
The Boss Fight bonus triggers when three or more Boss Doors land. During this feature, the game awards free spins and introduces Crit Gems, which mark board cells. A wild landing on an unmarked cell creates a x1 Crit Gem, while a wild on a cell that already holds a Crit Gem doubles it to x2. Winning clusters that land on Crit Gem cells receive the gem's multiplier applied to their payout. The Boss Fight can retrigger: if three or more Boss Doors land again during the bonus, more spins are added.
The Loot Vault bonus activates with six or more Loot Coins. This hold-and-win feature grants three respins. Landing new coins resets the respin counter. Vault Keys collect locked coins, securing their values on the board.
Three bonus buy options are available: RAID BOOST costs 0.35x the bet, Boss Fight costs 135x the bet and Loot Vault costs 176.2x the bet.
