Bass Cash Monstrosity is a medium-volatility online slot from Alchemy Gaming with an RTP of 96.00% and a maximum win of 10,000x.
A murky, wreck-strewn seabed sets the scene for Bass Cash Monstrosity, Alchemy Gaming's continuation of its Bass Cash line, where a small, harmless-looking fish gradually mutates into a fanged sea monster as the reels feed it unwon cash and jackpot symbols. The bigger it grows, the larger the stash of prizes it is holding for players to try to claim back. Play takes place on a 5x4 grid worth 1,024 ways to win, chained reel dividers reinforcing the fishing-boat framing.
Wins on the paylines come from 10 through A royals, worth 0.8x to 1.2x the stake for five of a kind, and from reels, hooks, tackle boxes and Winston the dog symbols paying 1.8x to 4x for the same. A wild lands on every reel except the leftmost and fills in for any of those regular symbols.
Fisherman collector symbols appear only on the far-left and far-right reels, and landing one triggers Cash Collect, gathering every cash value on the grid (0.2x to 10x) along with whichever jackpot tier is showing — Mini pays 15x, Minor pays 50x, Major reaches 250x, and Mega tops out at 5,000x — with two Fishermen in the same spin doubling the take. Cash multipliers can also land on the leftmost reel in either the base or bonus game and apply to whatever cash prizes are collected. Separately, Winston himself may dive in on any spin to reveal a cash prize, sometimes carrying its own random multiplier.
The monster fish quietly stashes any cash and jackpot prizes that go uncollected, building a pile worth up to 10,000x, and players get random chances throughout the base game to catch it and claim everything stored inside — miss the catch and the stash resets to 5x rather than carrying over. A bonus symbol collected above the grid fills five reel slots to start the Bass Cash Bonus, where an expanded Fisherman occupies the leftmost reel while the remaining four spin in cash and trophy symbols; cash is paid as it lands, trophies stack above the grid, and the round runs until three matching trophies complete a set, paying its linked jackpot.
Landing three, four or five scatters opens ten free spins, with bronze, silver or gold scatters — upgraded over successive 50-spin stretches once free spins have first triggered — adding one, two or three Fisherman symbols to a collection trail from the start. Collecting 4, 8 or 12 Fishermen along that trail awards a x2, x3 or x10 cash multiplier plus ten extra spins each time. The monster fish keeps stashing during the round too, and its haul can be claimed at the finish — or, if it escapes, chased again through a priced Bonus Recharge. Depending on which scatter tier has already been unlocked, the whole free spins round can also be bought outright for 100x to 200x the stake.
The RTP is 96% by default, with 94% and 92% alternative configurations also available. Volatility is medium, hit frequency is 15.5%, and the maximum win is 10,000x the stake, across bets from 0.20 to 20 per spin.
