Jammin’ Jars 2 free spins at a casino are usually 10p each, so 100 spins are £10 of stake returning about £9.61 to £9.66 on average, depending on which published RTP applies (96.1% rising to 96.6% for the default version). The phrase also covers the Push Gaming sequel's own free spins round on its 8 × 8 grid.
100 spins at 10p average about £9.61–£9.66 back, depending on the RTP that applies.
The help screen at your casino shows which RTP figure the game is running.
The 50,000x max win is £5,000 on a 10p spin, a ceiling that very few spins approach.
None of our partners lists Jammin’ Jars 2 for welcome spins; PlayOJO's 80 spins are on Big Bass Bonanza.
Since 19 January 2026, wagering on UK bonus winnings can't exceed 10x.

Jammin’ Jars 2 free spins: casino offer or in-game round?
Two different things share this name. Casino spins are a promotion: the operator credits a number of spins at a stake it sets, on games it lists. The in-game free spins round belongs to Push Gaming's design and starts only when the right symbols land. A credited spin can trigger the in-game round, but otherwise the two have nothing to do with each other.
This page starts with the value of casino spins, because the RTP question on this game is less straightforward than on most. For offers on other games, see our free spins hub.
Jammin’ Jars 2 RTP: why the figure is a range
Our checked data records the Jammin’ Jars 2 RTP as 96.1% rising to 96.6% for the default version. Rather than guess which figure applies at a given casino, the safe approach is to treat the value of spins as a range and confirm the exact number in the game's own rules.

At casino-spin stakes the gap is small: 5p per 100 spins. The figure that changes value far more is wagering. For a broader look at how RTP affects spins, see our high RTP slots for bonuses guide and the expected value entry.
The sequel keeps the 8 × 8 cluster-pays grid and High volatility, but its ceiling is far higher.

On 100 spins at 10p, the original averages about £9.68 against £9.61–£9.66 for the sequel: a few pence either way. See Jammin' Jars free spins for the first game and Push Gaming free spins for the studio.
The 50,000x ceiling, read the right way
A max win of 50,000x the stake sounds like the headline, and at 10p it converts to £5,000. But on a High-volatility game, rare large outcomes take up a big share of the return, leaving ordinary spins to pay small amounts. A higher ceiling doesn't add to the RTP; it reshapes how the same return is spread.
Offer terms can also cap spin winnings well below the game's limit. Read the max win clause alongside the game's ceiling; our free spins max win page shows how.
Jammin’ Jars 2 free spins no wagering vs 10x wagering
With Jammin’ Jars 2 free spins and no wagering, the average winnings of £9.61–£9.66 from 100 spins at 10p are paid as cash. If the same winnings carried the UK maximum of 10x wagering, you'd need to stake about £96 more. At 96.1% RTP, that costs about £3.75 on average and leaves about £5.86; at 96.6%, it costs about £3.28 and leaves about £6.38.
The averages hide a practical problem: on a High-volatility game, the bonus balance often runs out before the wagering is done. That's why wager-free offers are generally the better deal for the same spin count. The 10x limit came in on 19 January 2026, as the Commission explained when it said promotions would be safer and simpler (opens in a new tab). The answer to does the 10x cap apply to free spins? explains how it applies to spin winnings, and free spins wagering explained works through more examples.
Jammin’ Jars 2 free spins no deposit: what's available
None of our partners offers Jammin’ Jars 2 free spins with no deposit, and none runs any no-deposit bonus. Each spin offer needs a first deposit or a £10 slots bet. Elsewhere, no-deposit spins at UK-licensed casinos are uncommon and usually small and capped. For the options that do exist, see can you get a bonus without depositing?
How to trigger free spins on Jammin’ Jars 2
The in-game free spins round starts when the trigger symbols described in the game's rules land on the grid. The help screen at your casino lists how many are needed, how many spins you get and what happens during the round. Because UK games must show this before you play, there's no need to rely on second-hand descriptions.
Credited casino spins can land the round exactly as paid spins can. Feature buys aren't part of how slots are supplied to players in Great Britain, so play is the only route in. Can free spins trigger the bonus round? explains how winnings from the round are treated under an offer.
Launched in June 2021, months before the UK design rules
The game was released on 2 June 2021. Less than five months later, the UK's online slot design rules took effect, and further changes have followed since. The UK version has to meet all of them.

Frequently asked questions
What is the Jammin’ Jars 2 RTP?
Our checked data gives the Jammin’ Jars 2 RTP as 96.1% rising to 96.6% for the default version. That means 100 casino spins at 10p average roughly £9.61 to £9.66 back over the long run. The precise figure for the copy you're playing is in the game's help screen, which UK rules require to be available before you play. Our RTP glossary entry explains what the percentage does and doesn't tell you.
How do you trigger free spins on Jammin’ Jars 2?
The free spins round is triggered by landing the trigger symbols described in the game's rules on the 8 × 8 grid. The help screen in the version at your casino gives the exact number needed, the spins awarded and how the round works. Casino spins can trigger it in the same way as paid spins, and in Great Britain the round can't be bought. See the free spins round entry for the general mechanics.
What is the max win on Jammin’ Jars 2?
The stated max win is 50,000x the stake, which is £5,000 on a 10p spin and £100,000 on a £2 spin. Wins near that level are very rare, and the ceiling doesn't raise the RTP. A casino's offer terms may cap spin winnings much lower, so check the max win clause in any promotion. Our casino bonus max win page explains how game and offer caps fit together.
Is Jammin’ Jars 2 better than Jammin' Jars for free spins?
On published figures, the original has a slightly higher RTP (96.83% against 96.1%–96.6%), worth a few pence more per 100 spins at 10p. The sequel has the higher ceiling, 50,000x against 20,000x. Both are High volatility on an 8 × 8 grid. For casino spins, the offer's wagering, expiry and max win matter far more than the choice between them. Compare on our Jammin' Jars free spins page.
Can I get Jammin’ Jars 2 free spins with no deposit?
Not from any of our partners, which run no no-deposit bonuses; each spin offer needs a first deposit or a £10 slots bet. No-deposit spins at UK-licensed casinos are uncommon, and those that exist tend to have small spin counts and low winnings caps. Check any offer's licence, wagering and max win before signing up. Our free spins no deposit page covers what's genuinely available.
Why might a casino show a different RTP for Jammin’ Jars 2?
Some games are supplied with more than one RTP setting, and our checked data records a range for this game rather than a single figure. Under UK rules, the RTP must be shown before you play, and the rules, payouts and probabilities can't change while the game is available. Always use the figure in the help screen at the casino you're using. Our RTP information rules page explains the requirement.
Are Jammin’ Jars 2 free spins winnings paid in cash?
Only if the offer is wager-free. Our partners' spin offers pay winnings without wagering, though their spins are on their own listed games. If another casino adds wagering, the winnings become a bonus balance that has to be staked up to 10x before withdrawal. On average, 10x wagering costs about £3.28 to £3.75 on 100 spins' winnings here. Our answer to are bonus wins paid in cash? explains the difference.
Can Coral or Ladbrokes free spins be used on Jammin’ Jars 2?
Only if the game appears on the offer's list of selected games, which each brand shows on its promotion page. Our checked offer data doesn't name Jammin’ Jars 2 as one of their spin games, so check before you opt in. PlayOJO's 80 spins are on Big Bass Bonanza only. Spins can't be switched to an unlisted game. The reasons are covered in can I choose my free spins slot?
When did Jammin’ Jars 2 come out?
Jammin’ Jars 2 was released on 2 June 2021, according to our checked data. That was just under five months before the UK's online slot design rules took effect on 31 October 2021, banning autoplay, turbo and slam-stop and setting a 2.5-second minimum spin. The UK version must meet those rules, along with the 2025 stake limits. Our free spins new slots page covers spins on more recent releases.
