Rat King

The Brothers' take on Rat King

Rat King is Push Gaming's medium-volatility cluster slot, dressed in a sewer-rat aesthetic that the studio fully commits to. Six reels, six rows, a 10,000× cap, and a Push Bet that gives you real volatility control.

The grid is 6×6 with cluster pays — five or more matching symbols anywhere on screen pays out, no paylines. The signature mechanic is Dud Symbols and Collection Boxes: certain rats land as Dud Symbols (visually distinct, locked in place), and Collection Boxes appear at the top of reels. As you string clusters, Dud Symbols fill into Collection Boxes; fill enough and the bonus triggers — 10, 15, or 20 free spins for 3, 4, or 5 Rat King scatter symbols. The Push Bet (an optional stake doubler) increases bonus trigger frequency and bumps RTP from 96.30% to 96.35%.

Default RTP is 96.30%, with five lower variants down to 88.19% — a wider spread than most studios publish. Volatility is medium, which is the slot's main appeal. Max win caps at 10,000× the stake, with the max-win frequency landing around 1 in 11.2 million spins (or 8.3 million with Push Bet on). Bet range runs from 10¢ to €/$100.

The Brothers like Rat King because Push Gaming nailed the volatility tuning. Razor Shark and Razor Returns from the same studio play at maxed-out volatility with the bankroll consequences that implies; Rat King keeps the studio's mechanical complexity but at a friendlier cadence. The sewer aesthetic is committed enough to be charming — which is rare for cluster slots, where the visuals usually feel like wallpaper. We'd pick this on any tight session and most casual ones.
