Jammin' Jars 2

What these figures mean for Jammin' Jars 2

Jammin' Jars 2 is a sequel that changes the price structure of the original in a way most players would not expect. Push Gaming publishes two return settings for it, 96.40% and 94.40%, against 96.83% and 94.25% for the first game. The sequel's better setting is therefore worse than the original's by 0.43 of a point, while its weaker setting is better by 0.15. The spread between the two settings shrinks from 2.58 points to exactly 2.00. If you know which build a casino runs, the choice between the two games can go either way.

Put in money, the house edge on the sequel is 3.60% on the higher build and 5.60% on the lower. Ten thousand spins at 10p — £1,000 of turnover — cost about £36 on average at 96.40% and about £56 at 94.40%. On the original, the same session costs about £31.70 or £57.50. So at a casino running both games on their top settings, the original is the cheaper of the two by roughly £4.30 per £1,000; at a casino running both on their lower settings, the sequel is cheaper by £1.50. The difference between the settings inside either game is far larger than the difference between the games.

Push's page for this title also words its RTP note differently from its other pages: it says that, due to changes in regulations, RTPs may vary per casino in some markets, and that the figure appears at the top left of the loading screen. The studio does not name the markets. The practical instruction is the same as elsewhere — look at the loading screen — but the wording is a reminder that the setting you see can depend on where the casino is licensed, not only on the operator's preference.

The headline number that will draw players is the ceiling: a highest observed win of 50,000x, two and a half times the original's 19,998.5x and level with Big Bamboo's. Push, as on every page, presents it as observed rather than as a cap, and publishes no odds. A larger observed ceiling alongside a lower top return is a recognisable trade in slot design: some of the return a player would otherwise collect in ordinary sessions is moved into rarer, larger outcomes. Push does not publish the distribution that would let us confirm that here, so treat it as a likely shape rather than a measured one.

The mechanics explain where those outcomes could come from. Wins still need five or more matching fruit, as in the original, but the sequel adds several layers. Gold vinyl symbols fill a meter beside the DJ; at its maximum level, the Giga Jar feature can trigger. Instant prizes, worth up to 1000x, appear in blue tiles in both the base game and the free spins, and five or more adjacent instant prizes turn purple and pay as a cluster of their own. A random Fruit Blast fires one to three giant fruits that burst into a cluster. Three or more wild jars start six free spins.

One proportion on the page is worth noticing. The largest instant prize Push names is 1000x, and the observed ceiling is fifty times that. Nothing on the page is described as paying anywhere near that on its own, so the top outcomes have to come from combinations — clusters of instant prizes, wild jar multipliers added to paying clusters, and the Giga Spins running on. That is the practical meaning of the 50,000x: it is the product of several features stacking in one sequence, which is exactly why it is rare.

The Giga Jar is the centrepiece. It lands as a 2x2 block, or as a paying 3x3 or 4x4 instant-prize block, and awards eight Giga Spins, during which a wild jar multiplier next to a paying cluster adds to that cluster's win, and instant prizes can bring one or two extra spins. When the feature ends, a new Giga Jar appears already boosted to level two, three or four. That detail suggests the game carries part of its progress forward rather than starting every feature from scratch, which rewards continued play and makes stopping just after a feature slightly costlier than it looks.

Push lists no bonus buy for this title.

Before playing, the checks follow from the comparison with the original. Read the RTP on the loading screen: 96.40% is the better setting, 94.40% the weaker. If the casino carries both games, compare their settings rather than their names — the original at 96.83% is cheaper than either setting of the sequel, and the original at 94.25% is dearer than either. And treat the 50,000x as a figure the studio has seen rather than one it promises; nothing on the page says how often anything near it happens.

The short version: a sequel with a bigger observed ceiling, a slightly lower best return, a slightly better worst one, and a feature that keeps part of its progress. Which Jammin' Jars is the better deal depends entirely on what the lobby is running.

The RTP you get depends on the casino

Push Gaming publishes 2 different RTP builds of this game and each casino chooses which one to run. Most review sites print a single number; these are all the builds the studio publishes for Jammin' Jars 2, highest first. Push Gaming names no default among them, so the figure at the top of this page is simply the highest it publishes.

On £100 of turnover the gap between the highest and lowest build here is £2.00. A casino is not obliged to tell you which build it runs, so treat any single RTP figure — including ours — as the best case until you have checked the game's own info screen in the lobby.
