RTP 96.3%: what it means
Rat King has an RTP of 96.3%. If €1,000 were staked in total over a very large number of spins, about €963 would theoretically be paid back and €37 would stay with the casino. It is not a forecast for one session: over a few spins everything is chance, and over time the edge stays with the casino.
That is below the median RTP (96.5%) of the 593 slots with data in our catalogue — higher than 26% of them. Across the 83 Push Gaming slots we track, the median RTP is 96.35%. 96.3% is the default value published by Push Gaming; a casino may offer Rat King in a version with a different RTP, so check the game’s info screen.
Max win: 10,000×
The top prize on Rat King is 10,000× the stake, i.e. €10,000 at a €1 stake. It is a theoretical cap: most sessions end without coming anywhere near it. That is above the median (7,500×) of the 544 slots in our catalogue that publish a max win; 104 are higher.

Bonus buy
