Jackpot slots pay a prize on top of the normal paytable: a progressive jackpot that grows with every stake, a network feature such as Jackpot King, or a set of fixed jackpots worth a multiple of your bet. Below are the jackpot slots we have reviewed, from Mega Moolah’s four progressive jackpots to Wolf Gold’s 1,000x Mega, with each game’s jackpot type and RTP and what the jackpot costs you in the base game. 18+, play responsibly.

Types of Jackpot Slots
Network Progressive Jackpots
A small part of every stake, at every casino that runs the game, goes into a shared pot that keeps growing until someone wins it. That is how Mega Moolah builds a top prize that starts in the millions, and why Age of the Gods shares four progressive jackpots across Playtech’s whole Age of the Gods series. In both games the jackpot round can start at random on any spin.
Jackpot King
Jackpot King is Blueprint Gaming’s progressive feature, added to selected games. Genie Jackpots carries Jackpot King, and Deal or No Deal Megaways uses Jackpot King Deluxe. Blueprint also releases separate Jackpot King versions of some of its hits; our King Kong Cashpots review covers the standard game, which has no jackpot, so check the game’s name and information screen to see which version you are playing.
Local and Mystery Progressives
Some progressives are smaller and tied to a single game. Divine Fortune combines fixed Minor (20x) and Major (100x) prizes with a progressive Mega jackpot, Mega Joker adds a small progressive won at random, and Shining Crown has Jackpot Cards, a mystery bonus that can appear on any spin and offers four progressive levels.
Fixed Jackpots
Fixed jackpots pay a set multiple of your stake, so you always know what each one is worth. Wolf Gold pays 30x, 100x or 1,000x from its Money Respin, Mustang Gold offers 50x to 1,000x through a pick game, Fishin’ Pots of Gold runs from a 15x Mini to a 5,000x Mega, Huff N’ Puff tops out with a 5,000x Grand and Congo Cash with a 2,000x Grand.
Multi-Level Jackpot Features
Big Piggy Bank and 88 Fortunes each have four jackpot levels, from Mini to Grand. In Big Piggy Bank you win them by collecting matching jackpot symbols; in 88 Fortunes, which levels you can win depends on your stake, as explained below.
How Jackpots Affect RTP
A progressive jackpot is paid for by the players, so part of the RTP goes into the pot instead of the base game. Divine Fortune returns 96.59% overall but about 92.52% without the jackpot, Age of the Gods includes a 0.99% jackpot contribution in its 95.02%, and Mega Moolah’s base game returns 88.12%, one of the lowest figures in our catalogue. Unless you win the jackpot, you are playing a game that pays back less than a typical slot.
Fixed-jackpot games work differently. Their jackpots are part of the normal paytable, so their RTPs sit in the usual range: 96.01% for Wolf Gold and 96.53% for Mustang Gold, for example. They will not change your life, but you are not giving up as much of each stake to chase a long shot. Mega Joker is the exception among progressives, with up to 99% RTP, but only at the highest coin level in Supermeter mode.
Does Your Stake Change Your Jackpot Chances?
In some games it does. In 88 Fortunes, the number of active gold symbols, and so which jackpots you can win, depends on your bet level, and the Grand is only in play with all five active. In fixed-jackpot games such as Wolf Gold and Mustang Gold, the jackpots are multiples of your stake, so a bigger bet means a bigger prize. Check the paytable before you play, and remember that UK rules cap online slot stakes at £5 a spin (£2 if you are 18 to 24), jackpot games included.
How to Choose a Jackpot Slot
- Decide what you are chasing. A network progressive offers the biggest top prize but the lowest base-game return; fixed jackpots are smaller but cost you less.
- Check the RTP version. Several games here come in lower-RTP versions. The information screen shows the one your casino runs.
- Read the jackpot rules. Look for whether jackpots depend on your stake, and whether the top prize is progressive or fixed.
- Set a budget first. Jackpots are rare by design, so play with money you can afford to lose and treat any jackpot as a bonus, not a plan.
Playing Jackpot Slots in the UK
All the games above run at UKGC-licensed casinos with the same rules as other slots: stakes of up to £5 a spin (£2 for 18 to 24-year-olds), no bonus buy and bonus wagering capped at 10x. Big wins, jackpots included, can trigger extra verification before the casino pays out, so it helps to verify your account early. Our fast withdrawal casinos guide compares how quickly our partner casinos pay. For more slots by type, see high RTP slots and Megaways slots.

FAQ
What is a jackpot slot?
A slot that pays a jackpot on top of its normal wins. The jackpot can be progressive, growing with every stake until someone wins it, or fixed, paying a set multiple of your bet.
What is the difference between progressive and fixed jackpots?
A progressive jackpot grows as players stake on the game, often across many casinos, so the top prize can be very large but the base game usually pays back less. A fixed jackpot is always the same multiple of your stake, such as Wolf Gold’s 1,000x Mega.
Which jackpot slot has the biggest jackpot?
Among the games we review, Mega Moolah has the biggest top prize: its Mega jackpot is a network progressive that starts in the millions.
Do jackpot slots have a lower RTP?
Progressive jackpot slots usually do in the base game, because part of every stake funds the jackpot. Mega Moolah’s base game returns 88.12%. Fixed-jackpot slots such as Wolf Gold (96.01%) have typical RTPs.
Can I win the jackpot on a minimum bet?
It depends on the game. In 88 Fortunes the Grand is only in play at the bet level that activates all five gold symbols, while fixed jackpots are paid as a multiple of whatever you stake. Check the paytable before you play.
What is Jackpot King?
Blueprint Gaming’s progressive jackpot feature, added to selected games such as Genie Jackpots. Deal or No Deal Megaways uses the Jackpot King Deluxe version.
