Towers, Multipliers and Bonus Rounds in One Slot Room

Tower Climb is the feature where each winning spin advances you one level up the fortress tower, and every level adds a multiplier to your next payout until the climb ends or you trigger a bonus round.

A Scatter Symbol is the fortress gate icon that triggers the bonus round when three or more land anywhere on the reels during a single spin, regardless of payline position.

Locked Wilds are wild symbols that stay in place for all slot feature notes once the bonus round starts, helping you complete winning combinations without disappearing after each spin.

A Multiplier Step is one level of the fortress tower that adds a fixed multiplier value to your next win, with higher tower levels offering larger multipliers until the feature resets.

RNG Seed is the unique starting value the random-number generator uses for each spin, determining symbol positions and tower outcomes before the reels stop so results cannot be altered mid-spin.

A Paytable Cap is the maximum payout a single spin or bonus round can award, listed inside the Fortress Fortune paytable so you know the highest possible win before you play.
