What makes Jammin’ Jars different
Jammin’ Jars is an 8×8 grid cluster-pays pokie by Push Gaming, released in 2018. It combines cluster pays with a unique Rainbow Wild mechanic where the Wild actively moves toward the largest cluster of symbols on the grid each spin, growing a multiplier as it travels.
The Rainbow Wild
One or more Rainbow Wild symbols appear on the grid. After each spin, each Rainbow Wild moves one position toward the largest cluster of matching symbols currently on the grid. When the Wild joins that cluster, it contributes to the win and its multiplier (which starts at 1x and increases by 1 with each step taken) applies to the cluster win.
A Rainbow Wild that has moved several times before joining a cluster can carry a multiplier of 5x or higher. Multiple Rainbow Wilds on the grid each travel and multiply independently.
Free Spins
Three or more Jar scatter symbols trigger 8 free spins. During free spins, Rainbow Wilds are sticky — they remain on the grid and continue moving each spin without disappearing after contributing to a win. Their multipliers keep growing for the duration of the round.
Landing 3+ scatters during free spins adds 4 more spins to the counter.
The combination of multiple sticky Rainbow Wilds with growing multipliers across an 8×8 grid of clusters is where the game’s 20,000x maximum win becomes achievable.
RTP and volatility
Push Gaming publishes 96.83% RTP. Jammin’ Jars is high-volatility despite the large grid — cluster pays generate wins more frequently than paylines, but the Rainbow Wild multiplier mechanic concentrates significant value in free spins rounds with multiple active Wilds.
What it costs per hour
At NZ$0.40 per spin and 400 spins per hour: NZ$160 wagered × 3.17% house edge = approximately NZ$5.10 expected loss per hour.
### Q: What is the difference between Jammin’ Jars and Jammin’ Jars 2?
A: Jammin’ Jars 2 (2021) adds a tumble mechanic, a Giga Wild feature (larger Wild symbols), and a modified free spins structure with an increased multiplier ceiling. The original game has the simpler Rainbow Wild travel mechanic. Both are high-volatility cluster-pays titles; the sequel has a higher maximum win potential.
### Q: How does the cluster pays mechanic work on an 8×8 grid?
A: Any group of 5 or more identical symbols that are horizontally or vertically adjacent counts as a winning cluster. Winning symbols are removed and new ones fall from above (avalanche mechanic), which can create consecutive clusters from a single paid spin. Larger clusters pay proportionally more than minimum clusters of 5.
### Q: Can multiple Rainbow Wilds be active at once?
A: Yes. The game can display multiple Rainbow Wilds simultaneously, each moving toward the nearest large cluster and each carrying its own multiplier. During free spins, all active Wilds are sticky and grow their multipliers independently throughout the round.
Playing Jammin’ Jars at NZ casinos
Jammin’ Jars returns 96.83% over the long run — well above the 78% minimum return required at NZ land-based pokies venues. At the NZ$0.20 minimum bet, the 3.17% house edge produces an expected hourly loss of approximately NZ$2.54 at 400 spins. At the NZ$100 maximum bet that rises to approximately NZ$1,268. The 8×8 cluster pays grid is one of the larger playing fields among reviewed titles, and the Rainbow Wild’s active movement mechanic gives the base game a dynamic quality not found in static Wild formats.
High volatility governs Jammin’ Jars sessions despite the large grid. The cluster pays format generates wins with reasonable frequency on the 8×8 field, but the Rainbow Wild’s multiplier is small during base game play — it only builds significant value after travelling multiple positions. The free spins round, where Rainbow Wilds become sticky and keep growing their multipliers across 8 spins without resetting, is where the game’s significant outcomes are concentrated. Sessions with few free spins triggers or rounds where Rainbow Wilds travel little before the round ends will produce modest returns.
The 20,000x maximum win requires multiple sticky Rainbow Wilds carrying large accumulated multipliers to land on or adjacent to a major cluster during free spins — a statistical edge case. At NZ$0.20 per spin it represents NZ$4,000; at NZ$100 it represents NZ$2,000,000. Expected hourly cost at the NZ$0.20 minimum is approximately NZ$2.54; at NZ$0.40 approximately NZ$5.07.
