Bass Cash X UP King Millions Slot Review
Competitive bass fishing hands out trophies for a fish that goes straight back in the water. It gets weighed, then released, and the angler keeps the silverware.
Bass Cash X UP King Millions builds its prize structure on much the same logic. Trophies stack up above the reels, and a four-tier jackpot ladder climbs from a 15x MINI to a 1,000x MEGA, with two King Millions progressives sitting above it.
Alchemy Gaming quote 86% base RTP, with a further 4.50% coming back through the jackpot contribution for a stated 90.50% total, at medium volatility.
The studio have been working this range for a while, and this one bolts two of its lines together. The multiplier trail is the X UP mechanic from Bass Cash X UP.
The wheel and its pair of progressives arrive from Bass Cash Deluxe King Millions, and here they share the same grid.

Base Game & Features
The grid is a 5×4 with 1024 ways to win. Wins begin on the leftmost reel and pay left to right across adjacent reels only, and just the highest win on each way is paid.
Line pays are deliberately modest. Five Dogs, the top symbol, return 4x your stake, a tackle box five-of-a-kind pays 3x and green fish 2x, with the card ranks tailing off below that. The wild is worth 1.5x for three.
Nothing on the paytable, in other words, pays more than 4x for a full line. The cash values printed on the fish are what the game is actually built around. Alchemy Gaming put the hit rate at 20.57%, and stakes run from 0.20 to 20.00 per spin.

Cash Prizes and the Fisherman Collect
Cash prize fish land with values printed on them, alongside MINI, MINOR, MAJOR and MEGA jackpot fish. None of it pays until a Fisherman turns up.
Fisherman collect symbols appear on reels 1 and 5, and a single one sweeps every cash and jackpot prize showing on the reels. Two Fishermen collect the lot twice.
The X UP Trail
Running alongside the collect mechanic is the X UP trail, a multiplier ladder fed by tokens.
Two red scatters collect one token, and the active level applies to every cash and jackpot prize during free spins. In the base game it takes a gold scatter to apply it.
Blue scatters do something more lasting. Two of them permanently upgrade an X UP level, working down from the top of the trail, and once the whole trail has turned blue any further pair doubles the top level again, to 15x.
King Millions Tokens
King Millions tokens are collected separately from the X UP ones. Each buys a chance at the bonus wheel rather than a guaranteed spin of it, and the trigger itself is random.

Bass Cash X UP King Millions Bonus Features
Three separate routes lead out of the base game, and only one of them is a conventional free spins round.
Free Spins
Three red scatters in the base game trigger eight free spins, and whatever X UP multiplier level you’ve built is active throughout. Every cash and jackpot prize collected in the round is multiplied by it.
Two red scatters landing during the round award two more spins and another X UP token, so the multiplier can keep climbing while you’re still in there.
Bass Cash Bonus
Bonus symbols work on a collection meter with five slots above the reels. Each one that lands fills a slot, and filling all five begins the round.
An expanded Fisherman then occupies reel 1 while reels 2-5 spin in cash prizes and trophy symbols. Every cash prize that lands is collected, and trophies gather above the reels.
The round keeps going until three matching trophies have been collected, at which point the jackpot attached to them is awarded and the bonus ends.
King Millions Bonus Wheel
Collecting King Millions tokens gives a random chance of spinning the King Millions wheel, which holds two progressives and cash prizes worth between 7x and 100x your bet. The chance of triggering a progressive award rises with your bet, so the two biggest prizes on the wheel are effectively stake-gated.
Bonus Buy
There’s no bonus buy. No purchase control appears in the interface or the bet menu, so every feature has to arrive on its own.
Our Honest Verdict
Overall Rating: 6.7/10
Underneath the rods and trophies, this is a cash-collect slot with three routes to a decent finish. Line pays barely register, which is convention for the format rather than a fault. The fish carry the money, and the Fisherman decides when you see it.
The X UP trail is the cleverest part of it. A multiplier built in the base game that then applies to every prize collected across eight free spins gives the round a ceiling worth working towards, and blue-scatter upgrades stick permanently, so progress carries over.
The Bass Cash Bonus is a more familiar hold-and-win, and it’s where the jackpot ladder pays out.
The harder part to defend is the price of admission. Those two King Millions progressives are the reason to turn up, and their trigger chance scales with your stake, so the game’s biggest prize is the one it quietly wants you to bet up for.
Jackpot collectors who know this range and fancy the multiplier trail bolted on will get on with it. Anyone hunting a big multiplier off a small stake is in the wrong boat.
