Cog Collector
Cog Collector is a Zavrune Gaming pay-anywhere slot on a 6x5 grid, set in a steam-powered clockwork workshop where cascading wins feed a growing multiplier and Toolboxes collect Prize Cogs.
By the Reel Bulletin desk · Updated 9 Nov 2026
An Engineer and a wind-up toy mouse run this steam-driven workshop. On the 6x5 board, the Engineer, Copper Stove, Hourglass and Valve Wheel are the main pays, with card values from 10 to A beneath them. Any eight or more matching symbols score wherever they sit, and winners are cleared so replacements can cascade in.
With each winning cascade, a multiplier above the reels grows, and it applies to every win. Prize Cogs carry their own values, and once the cascades are done a Toolbox gathers them up. Wind-up Mice are the bonus symbols: three, four or five open one of three tiers of free spins, starting with the Bonus and Super Bonus, and the multiplier holds between spins there. A Get Bonus menu groups the boosted modes and direct buys.
Base RTP is 96.01% and the top win is 20,000x the bet, available in every mode. Volatility is very high, so that ceiling is balanced by long stretches of smaller outcomes. Hyper Boost costs 8x (96.02%). The buys are Bonus at 120x (96.08%), Super Bonus and Mystery Crate at 360x (96.04% and 96.03%) and Toolbox Spin at 400x (96.07%).
