How Misery Mining plays
Misery Mining uses a 7x7 grid where play begins inside a central 3x3 active area offering 27 ways to win. As barriers move outward, the active area can expand up to the full 7x7 grid with up to 823,543 ways to win. Hit frequency is 28.57%, volatility is extreme, stakes run from 0.20 to 100 in the casino's currency, and there is no progressive jackpot.
Collapsing Mine, xBomb Wilds and xBomb Mining
xBomb Wild Multiplier: Wilds substitute for most symbols. When an xBomb explodes, it clears neighbouring symbols and raises the win multiplier for the next collapse. Exploding xBombs next to barriers also move those barriers outward in the Collapsing Mine, and xSize features further expand the active area.
xBomb Mining: On a spin with no wins, no xBomb wilds, and fewer than three Scatters on the grid, the remaining Scatters turn into explosives that trigger a new collapse and raise the multiplier.
Misery Freespins (Mouse and Rat modes)
Misery Freespins trigger at an average probability of 1 in 220 spins when you land 3 Scatters, or when 1 or 2 Super Scatters land alongside regular Scatters.
Choosing Mouse mode or Rat mode
Before the bonus begins, the player chooses between Mouse mode and Rat mode. Rat mode starts with 3 spins, and landing coin wagons or Super Scatters resets the spin counter back to 3.
Feature buy
A feature buy menu is available with prices ranging from 66x to 1000x the base bet according to Nolimit City's official page. Feature buy may be removed in some regulated markets, and availability and prices depend on the casino. Because buying features concentrates variance, read our bonus buy guide first.
Is it worth playing?
Extreme volatility (with a 1 in 60 million probability for the 70,000x max win) means prolonged dry spells between major hits, and other RTP settings may exist depending on the casino alongside the published 96.09% RTP. Try the free demo above, set a strict stop-loss, and see our RTP and volatility guide. Play responsibly (18+, see responsible gambling).
