About this Slot
Coo Boss is a farm-themed slot from Nox Gaming with an RTP of 96%, high volatility, and a maximum win of 50,000x. The game features 5 reels across 4 rows with ways-based paylines.
Bottle Caps land on any reel and carry bet values. The Boss lands only on reel 5 and collects all Bottle Caps and Golden Sunflowers currently on the board, paying out their combined total value.
Golden Sunflowers land on any reel, carry their own values, and count toward the cap collection mechanic. When three or more Golden Sunflowers land anywhere on the reels, they trigger the Hold & Win bonus round.
The Hold & Win bonus starts with all Bottle Caps and Golden Sunflowers locked in place and awards three respins. Each new Bottle Cap or Golden Sunflower that lands during respins resets the respin counter back to three. Special Caps appear only during Hold & Win and their effects stack throughout the round. The board can open extra side columns during Hold & Win, expanding the play area. The bonus ends when all respins are exhausted or the board fills completely.
Sky Drop appears on empty spins and drops 2-4 Bottle Caps onto the board, triggering an immediate collection. The Flock Call buy option raises the stake to 3x per spin and increases the frequency of both Sky Drop and Hold & Win occurrences.
Heavy Drop mode costs 50x per spin and guarantees 5-7 Bottle Caps per spin with a minimum of one cap valued at 20x. Heavy Drop includes The Boss collection mechanic on reel 5.
The Loft costs 100x bet, Rooftop costs 400x bet, and Stairwell costs 500x bet as direct bonus access options.
