Rattle Crown
Rattle Crown is a sewer-set cluster slot from Velnixa Games, ruled by a pitchfork-wielding Rat King, where Crown Wild multipliers from x2 to x100 combine inside winning clusters.
By the Reel Bulletin desk · Updated 5 Nov 2026
Beneath the city lies the Rat King's lair, where the crowned rat waits by the board, pitchfork in hand. A treasure hoard, pocket watch, diamond ring and wedge of cheese are the premium symbols, while A, K, Q and J are shaped from slimy pipework. The Crown Wild is the Rat King himself, while a Sewer Grate acts as the scatter.
Six columns and five rows host clusters of five or more matching symbols joined by shared edges. There are no cascades, so each board is scored once. Every Crown Wild holds a multiplier between x2 and x100; when several sit in one cluster, their values are added and the win is multiplied by the total. Three, four or five Sewer Grates unlock three different bonuses, each giving 10 spins with sticky Crown Wilds.
Base RTP is 94.38% with a 10,000x cap. Rat Bait is a 3x toggle (94.32%). Buys are Rat Swarm at 50x (94.35%), Gutter Bonus at 100x (94.39%), Sewer Bonus at 200x (94.35%) and Throne Bonus at 500x (94.35%). Volatility is very high, so most of the value arrives in rare spikes.
