BEARSERKER
Deep in the forest, a grizzly rules the reels. His jaws turn whole rectangles Wild, his claws raise their power, and The Rage makes every swipe count.
One Bite. A Wilder Board.
Bearserker is a 5×5 slot with nineteen fixed paylines, set beside a wild northern river. Two BITE symbols frame a rectangle of Wilds; SWIPE symbols cut across all five reels and raise their marks. The frozen math targets 96.30% RTP in the base game and every feature option.
Nineteen Lines Through The Wild
Five reels, five rows, one stake covering nineteen fixed lines. Matching symbols pay from the first reel, starting at three in a row. Wilds substitute for paying symbols; BONUS symbols remain protected.
The Jaws Open. The Paws Strike.
Two BITE marks define opposite corners of a rectangle. The jaws turn its eligible cells Wild in a diagonal wave. Each SWIPE cuts one cell on every reel; repeated hits raise a mark through 1×, 2×, 3× and 5×. A winning line uses its highest mark.
The Hunt Or The Rage
Three BONUS symbols open The Hunt; four or more open The Rage. Both start with ten free spins. The Hunt favours bite rectangles. In The Rage, every SWIPE adds one to a persistent multiplier that applies to the spin it raises. BONUS symbols can award extra spins.
Share of 500,000 complete ordinary paid rounds reaching each multiplier, including naturally triggered bonuses. Sampled with seed 30092026 from the source engine. High volatility is an editorial classification.
15,000× is the engine cap on one spin; reaching it during a bonus ends the remaining free spins. Round pace describes a typical base spin. Pending independent certification.
The Grizzly At The Reels
A current capture of the playable demo. The grizzly stands beside five reels of five symbols, with the stake and feature controls below.
A Rectangle Turns Wild
A captured Bite Spin after the jaws have settled. Two corner marks define the area; protected BONUS symbols are never turned Wild.
A Swipe Across Every Reel
The game’s original SWIPE symbol artwork. Each landed SWIPE creates a path across all five reels, and repeated hits raise the affected Wild marks.
Ten Spins In The Wilderness
The Hunt opens with ten free spins. Bite rectangles are its central feature, with a whole-board bite marking every Wild at 5×.
Every Swipe Raises The Stakes
The Rage also starts with ten free spins. Its persistent multiplier starts at 1× and rises by one for every SWIPE symbol; the spin that raises it uses the new value.
Pines, Stone And Wild Water
Original environment art from Bearserker: evergreen forest, a mountain river and a fire beside the waterfall. This is the same painted wilderness used by the playable demo.
The Rules Before The Roar.
The playable build uses demo credits and a local outcome authority. Frozen rules separate the resolved result from its animation. The source enumerates the returns and checks them through the production engine; independent certification remains pending.
RESOLVE
The outcome authority chooses the reel stops, bite rectangle and swipe paths, then settles the award before the presentation reads it.
REPLAY
Seeded draws reproduce the board and its Wild marks. The stake and bonus state stay with the outcome authority.
MEASURE
The base game and all five feature options are solved onto 96.30% of their own prices. The audit checks enumeration, money rounding, bonus guards and simulated rounds.
