The original Jammin' Jars from 2018 is still one of the most played cluster pays slots in existence. Push Gaming's sequel kept the core mechanics but added layers. Whether those layers make it better depends on what you valued in the first game.
Side-by-Side Comparison
The grid stayed at 8×8 and cluster pays still requires 5+ matching symbols. Both games use the same wild jar mechanic — sticky wilds that jump and build multipliers. The differences are in what sits on top of that foundation. JJ2 replaced the Rainbow feature with Fruit Blast, added Gold Vinyl progression, instant prize symbols, and the Giga Jar bonus. The max win went from 20,000× to 50,000× — a 2.5× increase. But the RTP dropped from 96.83% to 96.4%, and there's no bonus buy option in JJ2 (the original had an 84× buy in some markets).
What the Original Does Better
Higher base RTP. The original's 96.83% is genuinely good — JJ2's 96.4% is fine but noticeably lower. The original is also simpler. You spin, you hope for 3 jars, you enjoy the free spins. No vinyl collection, no level progression, no anxiety about losing 1,500 spins of progress because your phone died. For players who want a clean, focused experience where the wild jar mechanic is the entire game, the original is hard to beat. It also has an 84× bonus buy in certain markets, which JJ2 lacks entirely.
What JJ2 Does Better
Everything related to ceiling. The 50,000× max win is 2.5 times the original's cap, and the Giga Jar feature provides a path to get there that the original simply doesn't have. Instant prize symbols add a secondary win channel in both base game and free spins — you can land 1,000× from a single instant prize cluster. The Fruit Blast is arguably better than the Rainbow because it can trigger more frequently and converts cells to any fruit type, not just adding giant symbols. Visually, JJ2 is a clear upgrade with the nightclub setting, the DJ character, and smoother animations.
Which One Should You Play?
If you have 30 minutes and a moderate budget, play the original. Higher RTP, simpler mechanics, and you can hit a solid bonus in any session length. If you have 2+ hours, a larger bankroll, and want to chase something bigger, JJ2 is the one. The Giga Jar chase gives the session a goal that the original lacks. Some players alternate — starting with JJ2 for the Giga Jar hunt, then switching to the original if the grind gets too punishing. Just remember: switching means losing your JJ2 vinyl progress.
Frequently Asked Questions
Does Jammin' Jars 2 have a bonus buy?
No. Push Gaming doesn't include feature buy options in any of their slots. You trigger free spins by landing 3 or more Wild Jars naturally. The Giga Jar requires collecting 110 Gold Vinyls through regular play.
Why does the RTP change during play?
JJ2 uses a 5-level progression system tied to Gold Vinyl collection. You start at 96.1% and reach 96.6% at MAX level. The shift is small but real — Push Gaming designed it to reward longer sessions.
What happens to my Gold Vinyl progress if I close the game?
It resets to zero. This is the most punishing mechanic in JJ2. If you're chasing the Giga Jar, you need to commit to a single uninterrupted session. Browser refresh, tab switch, app close — all reset your progress.
Is the Giga Jar guaranteed at MAX level?
No. Reaching MAX level only unlocks the possibility. The feature triggers randomly when a Gold Vinyl lands at MAX. Some players report spending hundreds of additional spins at MAX before it activates.
Can I play Jammin' Jars 2 on mobile?
Yes. It runs on HTML5 with portrait mode support. The 8×8 grid scales well on phone screens, and Push Gaming optimized the touch controls for mobile play. Just make sure your screen doesn't auto-lock during a session.
