Lost Kingdom

Lost Kingdom is not a slot. It is a four-player fish shooter from KA Gaming, released on 2 October 2025 – an arcade game in which you aim a cannon at creatures swimming through a sunken city and are paid for what you hit. It returns 96%, and our session ran at $1.00 a shot.

A Drowned City

The screen is one continuous underwater scene rather than a grid: broken columns and archways receding into blue darkness, purple coral in the foreground, shafts of light from far above. No reels, no paylines, no spin button.

Creatures cross the screen in shoals – striped clownfish, seahorses, a drifting manta ray, a turtle, jellyfish, a passing shark and an anglerfish with its lure lit. Shooting them is the whole game.

Four Seats, One Tank

Three of the four corners carried the label “WAITING FOR PLAYER” throughout our session – four cannon positions around the same water, filled as people join.

The creatures on screen are shared, so a boss you have been wearing down can be finished by somebody else’s shot. It is closer to an arcade cabinet than to anything else on this site.

Every Shot Is A Bet

The economics are the reverse of a slot. A stake selector sits at the bottom with minus and plus buttons – ours was set to $1.00 – and that is the cost of a single shot, not of a round.

So a fish worth $4.00 is worth four shots, and one that takes six shots to kill has cost more than it pays. Our balance drifted between $100,428 and $100,693 – money going out with every press and coming back in irregular lumps.

The Payouts Land On Odd Cents

This is the detail that separates Lost Kingdom from most shooters. Hit values float up from each kill, and ours read $0.31, $1.41, $2.00, $3.13, $4.00, $5.00, $6.00, $10.00, $18.00 and $20.00.

Round numbers and odd fractions side by side. A game paying $1.41 and $3.13 is dividing something up – most likely awarding a share of a creature’s value according to how much damage each shot did. The consequence is that a target you did not finish can still pay you, which on shared creatures is fairer than winner-takes-all.

The Sea Queen

The big target is a tall, dark-haired woman in a blue gown with a fin-like collar behind her shoulders, filling a third of the screen when she appears.

Ours paid $259.00, announced in a green banner across the middle of the screen. At a $1.00 shot that is 259x – and it is the number that explains why anyone plays this rather than a slot. Nothing in the ordinary flow of fish comes within a tenth of it.

Three Weapons

Along the bottom centre sit three circular buttons showing different cannon types, one priced at $6.00 – special shots bought with the balance you are already playing with, at six times an ordinary one.

Coloured rings pulse around each hit and coins spill out of dying creatures – one screenshot caught eleven separate payouts resolving at once.

What KA Does Not Publish

KA keeps a public release spreadsheet giving RTP, volatility and maximum win for its games. Lost Kingdom is not in it, and the catalogues carry no ceiling either, so we have left both fields empty. In a shooter they would mean less than usual anyway: the return depends on which targets you choose and how much ammunition you waste.

What The Bet Changes

The shot value is the bet, and everything scales with it. A higher shot value does more damage, so expensive shots kill faster and claim a larger share of a shared target; a cheaper one stretches the balance but may leave you paying for kills somebody else completes. That trade-off is the only real decision the game asks of you.

More From KA Gaming

KA builds arcade games alongside its slots and they share an art style. Ice Dragon King is the studio’s other four-seat fish shooter with priced bosses, Tactical Flush moves the format onto dry land with three stake rooms, and Skeleton Party is a conventional 243-way slot drawn in the same manner.

Who It Is For

Lost Kingdom is for players who are tired of pressing spin. It is a proper arcade shooter – four seats, shared targets, a crosshair you aim yourself and a sea queen worth 259 times a single shot – and the sunken-city artwork is among the best KA has produced. The fractional payouts are the thing that makes it worth choosing over the studio’s other shooters: damage appears to be rewarded proportionally, so shots fired at a creature somebody else finishes are not simply lost. The caveat is the usual one for KA’s arcade output: no published volatility, no maximum win, and a return figure you take on trust. All six casinos we checked carry it.
