Features Rat King is a six-reel slot from Push Gaming with medium volatility and a reported RTP range of 88.19% to 96.30%. The game uses Collection Boxes at the bottom of the grid, where Star Multiplier Symbols are gathered during a round and added to the multiplier counter on the right. Bets range from 0.10 to 100.00, giving players a wide stake range in the demo version.
The Rat King Symbol acts as a scatter. When it lands in a Collection Box, it contributes to the Free Spins metre on the left side of the grid. Collecting three or more Rat King Symbols triggers the Free Spins feature, where each collected Rat King Symbol awards three additional spins. Star Symbols continue to add their multiplier values during this bonus round, increasing the total multiplier applied to the current spin.
