Fixed jackpot slots have a top prize that is set in advance, usually as a multiple of your stake, and it never grows from other players’ bets. Win it at 10p and you get the 10p value; win it at £1 and you get ten times as much. Because the prize is part of the normal paytable, the whole RTP is paid through the game itself, with nothing diverted to a shared pot.
A fixed jackpot is a set multiple of the stake (or a set cash amount) that never grows.
The prize is inside the ordinary paytable, so no slice of your stake goes to a shared pot.
Pound values scale with your stake: Wolf Gold’s 2,500× top win is £250 at 10p and £5,000 at £2.
Every UK land-based machine has a fixed top prize set by its category, from £100 on pub machines to £10,000 on B1.

What are fixed jackpot slots?
A fixed jackpot slot is one whose biggest prize is written into the paytable as a fixed amount, rather than built up from a share of every player’s stakes. Online, that amount is almost always a multiple of the total stake, such as 1,000× or 2,500×. On a land-based machine, it is usually a cash figure capped by law. Either way, you can read the top prize before you spin, and it is the same tomorrow as it is today.
Fixed jackpots are the oldest kind of slot prize. A three-reel classic slot machine paying a set amount for three sevens is a fixed jackpot game, and so is a modern video slot with named Mini, Major and Mega prizes that are set multiples of the bet. They form one of the three branches of jackpot slot machines, alongside progressive jackpot slot machines and must drop jackpot slots. The full list of formats is on our slot types hub.
How a fixed jackpot slot works
You choose a total stake. The paytable recalculates every prize, including the jackpot, as a multiple of that stake.
The random number generator selects the reel positions, or the outcome of a bonus such as a respin round, before anything is shown.
If the result matches the jackpot condition, for example five top symbols on a line, a full grid of money symbols or a jackpot segment on a wheel, the jackpot is paid.
Nothing resets and no pot is shared: the next spin offers exactly the same prize at the same stake.
Because the prize is fixed, the game’s whole RTP is delivered through its own wins. There is no contribution taken from your stake to feed a pot elsewhere. That is the main structural difference from a progressive, where part of each stake is set aside for a jackpot that only one player will collect.
Fixed jackpot tiers: Mini, Major, Mega and Grand
Many modern slots offer several fixed jackpots at once, usually inside a respin or collect bonus. In a typical hold and win round, special symbols lock in place and each one carries a cash value or a jackpot label; filling the grid or landing a named symbol pays the matching tier. Others use a jackpot wheel with segments for each tier. Our glossary explains the naming in Mini, Major and Grand.

Each game sets its own values, and they appear in the help screen. Pragmatic Play’s Wolf Gold is a well-known example, with fixed Mini, Major and Mega jackpots in its Money Respin feature; Pragmatic Play’s website (opens in a new tab) carries the studio’s game library.
Fixed jackpot slot maths: RTP, cost and max win
Wolf Gold makes a clear worked example. Our checked data lists a 96.01% RTP, medium volatility, 25 paylines and a 2,500× stake max win that includes the fixed Mega jackpot. Lower RTP settings exist, so the casino’s version may differ.

Two points follow. First, the jackpot’s pound value is directly tied to your stake, so a player at 10p and a player at £5 are chasing very different amounts with the same odds. Second, the cost per 100 spins rises in the same proportion; a bigger fixed prize always comes with a bigger stake. The slot cost calculator runs the same sums for any game.
Fixed or progressive version of the same game?
Some games are released in both forms, which shows what a progressive pot costs. Blueprint Gaming’s King Kong Cash Even Bigger Bananas lists a 96% RTP in its standard version and 94.99% in its Jackpot King version. On £100 of stakes, that is an average of £4 kept in the standard game against £5.01 in the jackpot version, with the difference paying for the network jackpot most players will never win. Our guide to Jackpot King and jackpot networks explains that system.
That is why the “jackpot” on a pub fruit machine is £100 at most: the maximum prize on a pub fruit machine is set by its category, not by the operator. Club machines in Categories B3A and B4 carry higher fixed tops, which our page on club jackpot machines covers. Category D machines have much smaller prizes, and Categories A to C are for adults aged 18 and over only.
Fruit machines often build up to the top prize through a cash pot or feature board, but the ceiling never moves. Online slots are not in these categories and have no statutory prize cap, which is why an online fixed jackpot can be thousands of times the stake.
Fixed jackpot slot examples
Any slot without a progressive pot has a fixed top prize, so the list is long. These examples from our checked data show the range of ceilings, from modest to very large:
Starburst by NetEnt: 96.09% RTP, low volatility, 500× max win.
Fire Joker by Play’n GO: 96.15% RTP, medium volatility, 800× max win on a three-reel layout.
Wolf Gold by Pragmatic Play: 96.01%, medium volatility, 2,500× including its fixed Mega jackpot.
Fishin’ Frenzy by Blueprint Gaming: 96.12%, medium volatility, 5,000× max win.
Big Bass Bonanza by Reel Kingdom: 96.71%, high volatility, 2,100× max win.
A slot’s max win and its named fixed jackpot are not always the same number. Wolf Gold’s 2,500× figure includes the Mega jackpot plus other wins in the same round, so check the help screen to see which is which. Casinos can also set their own overall caps, explained on our max win caps page.
How UK stake limits affect fixed jackpot slots
Because the top prize is a multiple of the stake, the online stake caps directly cap what a fixed jackpot can be worth. A player aged 25 or over can stake up to £5 a spin (since 9 April 2025); a player aged 18–24 is limited to £2 (since 21 May 2025), so the same 2,500× jackpot is worth £12,500 to one and £5,000 to the other. The Gambling Commission’s stake limit guidance (opens in a new tab) sets out the rules, and our online slot stake limits page explains them in plain English.
Neither cap changes the odds of hitting the fixed jackpot: on a standard fixed-prize slot, the chance per spin is the same at every stake.
Are fixed jackpot slots worth it? Pros, cons and who they suit
Advantages
You can read the exact top prize at your stake before you spin.
No slice of the stake is diverted to a shared pot, so the full RTP is in play.
Odds of the top prize do not depend on stake size on most games.
Wide choice, from low-volatility classics to high-volatility features.
Drawbacks
The ceiling is lower than the largest online progressives.
At small stakes, the pound value of the jackpot can be modest.
Named jackpots can be confused with the game’s overall max win.
High multiples usually mean high volatility and long dry spells.
Fixed jackpot slots suit players who want to know exactly what they are playing for and prefer the full RTP in the game itself. They are the natural choice for anyone working to a budget, because the cost and the ceiling are both visible before you spin.
Fixed jackpot myths and facts
“Fixed jackpots are easier to win.” Not necessarily. A fixed 5,000× prize can be just as rare as a progressive tier; the difference is how it is funded.
“Betting more improves the odds.” On a standard fixed-prize game, a larger stake raises the prize, not the chance.
“The machine is due after a long gap.” Each spin is independent, online and on modern machines; see are slot machines rigged for how fairness is checked.
“A pub machine can pay more than £100 if it has been filling up.” The Category C cap is £100 whatever the machine has taken.

Frequently asked questions
What is a fixed jackpot slot?
It is a slot whose top prize is set in advance, usually as a multiple of your total stake, and does not grow from other players’ bets. Because the prize sits in the normal paytable, the game’s whole RTP is delivered through its own wins, with no share sent to a shared pot. The jackpot’s pound value rises and falls with your stake. Most slots in a casino lobby work this way. Our jackpot slot machines page compares all three jackpot formats.
Is a fixed jackpot better than a progressive jackpot?
It depends on what you value. Fixed jackpots keep the full RTP in the base game and show the exact prize at your stake, while progressives charge an extra slice of each stake for a chance at a much larger shared pot. For a set budget, fixed games usually give better everyday value; progressives offer a higher ceiling at very long odds. Neither changes the house edge. Read our fixed vs progressive jackpots comparison for a full breakdown.
Does the jackpot get bigger if I bet more?
Yes, on most online fixed jackpot slots, because the jackpot is a multiple of the stake. Wolf Gold’s 2,500× top win, for example, is £250 at 10p, £2,500 at £1 and £12,500 at the £5 maximum. The chance of landing it usually stays the same at every stake, so a bigger bet buys a bigger prize at a proportionally higher cost per spin. In the UK the maximum is £5 a spin, or £2 if you are 18–24. Our should you bet max answer covers the trade-off.
What are Mini, Major and Mega jackpots?
They are named prize tiers, usually inside a respin or wheel feature, and on fixed jackpot slots each one is a set multiple of the stake. Landing a specific symbol, filling a grid or stopping a wheel on a segment pays the matching tier. Wolf Gold uses fixed Mini, Major and Mega jackpots in its Money Respin round. On progressive games the same names can refer to growing pots instead, so the help screen matters. Our Mini, Major and Grand glossary entry explains the naming.
Do fixed jackpot slots have a higher RTP?
Not automatically, but none of their RTP is diverted to a shared pot, so the base game delivers the full figure. Where a game exists in both forms, the fixed version often has the higher number: King Kong Cash Even Bigger Bananas lists 96% in its standard version and 94.99% in its Jackpot King version. Most fixed-prize slots in our checked data sit around 96%, with lower versions sometimes supplied. Check the help screen for your casino’s version, as our guide to finding a slot’s RTP explains.
What is the biggest jackpot on a UK pub fruit machine?
£100. Pub fruit machines are Category C gaming machines, which allow a maximum stake of £1 and a maximum prize of £100, and that ceiling is fixed by law rather than by the machine’s owner. Bigger fixed prizes exist only in other categories: £400 on B4, £500 on B2, B3 and B3A, and £10,000 on B1 casino machines. Category C machines are 18+ only. Our pub fruit machine guide explains how the prize structure works.
Are fixed jackpots the same as max win?
Not always. The max win is the largest total a single spin or bonus round can pay, and it can combine a fixed jackpot with other wins in the same round. Wolf Gold’s listed 2,500× max win, for example, includes its fixed Mega jackpot as part of a respin round. Other games have no named jackpot at all, so their max win is simply the top paytable outcome. The help screen states both. Our max win glossary entry covers the definition.
Can I win a fixed jackpot with free spins?
Often yes, if the game the free spins are tied to includes the jackpot in its normal play, but the prize is calculated at the free spin’s value. With 10p spins, a 2,100× top win on Big Bass Bonanza would be worth £210. Some offers also cap the amount you can win from free spins, so read the terms, which state the eligible games, spin value and expiry. Our free spins winnings page explains how winnings from spins are paid.
Why do fixed jackpot slots show different max wins at different casinos?
Usually because the casino applies its own overall win cap, or runs a version of the game with different settings, such as a lower RTP. The game’s multiple stays the same in the paytable, but the casino’s terms may limit the cash paid on a single spin or round. UK rules require game rules and the RTP or likelihood of winning to be available before you play, so the help screen should reflect the version in use. Our max win caps page explains the differences.
