About this Slot
Boomscale by RTP Labs combines fantasy, steampunk and sci-fi themes across 5 reels, 5 rows and 19 paylines. The game has an RTP of 96.5%, high volatility and a maximum win of 25,000x.
A Mystery Bonus tier is determined by the number of scatters that land after each spin. Landing 3 scatters triggers the Free Spin Bonus, which awards 10 free spins and increases the frequency of skill effects during the mode. Skill effects add multiplier wilds to the board during free spins.
Landing 4 scatters activates the Premium Bonus, also awarding 10 free spins but with increased skill distribution frequency and power compared to the Free Spin Bonus. Landing 5 scatters triggers the Epic Bonus. Fewer than 3 scatters awards a smaller result determined by the Mystery Bonus mechanics.
The Coin Bonus plays at 500x base bet and fills free positions with coins each round. The outcome depends on coin values and multiplier only. This bonus remains active until the player chooses to disable it.
Double Scatter increases the chance of scatters landing by 2 to 8 times, though it does not change the mechanics of bonus triggering. The skill system features a character that fires at the board on a set chance, with the server determining the actual result regardless of presentation.
