Jammin’ Jars uses an 8×8 cluster grid, with wild jars that move and build multipliers through wins. This guide explains the original Push Gaming game, its free-games trigger and the figures to check before choosing a casino.

Push Gaming calls this its highest observed win. It is not a theoretical maximum; the sample size is not stated.
Push Gaming: Jammin’ JarsFive or more matching symbols form a winning cluster on the 8×8 grid. The cascading format makes the next drop part of the sequence to follow: watch which symbols form a cluster and whether a jar contributes to its win.
The jar has two roles, wild and scatter. Its multiplier starts at 1× and applies to a win it helps form. Push Gaming’s launch description explains that jars move when there is a win and their multipliers grow. That makes the jar’s position and multiplier useful things to watch during a demo, rather than looking for a fixed payline.
Three or more jars anywhere trigger free games. A separate random Rainbow feature adds large fruit symbols.
Push Gaming lists two RTP versions in the facts above. Check the value in the game’s user panel or loading screen at your chosen casino; the title alone does not tell you which version it runs. RTP describes a long-run mathematical return, not the amount a short demo or paid session will give back.
Push Gaming also lists Bonus Buy. Check its availability and price in the game you open if you want that option.

No, the jars trigger an in-game feature rather than a casino welcome bonus. See Cluster wins and moving jars for the trigger.
