I've been into online slots since around 2019, mostly sticking to lower volatility ones for steady play. But every now and then I crave something more exciting, so I loaded up Jammin Jars again a couple weeks ago. The disco theme and thumping music always put me in a good mood. Played for about an hour on a rainy afternoon, had some small cluster wins building up, then suddenly the rainbow feature triggered twice in a row, dropping huge fruit symbols that cascaded into a bunch of payouts. Followed by free spins where the jars multiplied nicely. Ended up ahead enough for a coffee run the next day. It's definitely swingy, but that's the appeal. Came across this comprehensive guide https://jamminjarsonline.com/ that details the bonus rounds and how to spot when it's heating up.
