Firestorm Joker Slot by Zillion Games

5,250x on a 3x3 grid. That's five times what Firestorm Joker 777 caps at, squeezed onto the same nine cells. The bonus triggers when at least one coin lands on each of the three reels, or you skip the wait and buy in at 50x. Inside, coins lock with credit multipliers, empties respin, and new coins reset the counter to three. Fill all nine positions and the Grand drops at 1,000x - but with only nine cells total, a full board isn't the astronomical ask it is on a 5x4 or 5x5 grid. Major pays 150x, Minor 50x, Mini 25x, and any tier except Grand can appear randomly on respins.

The Joker Wild pulls more weight here than in most Hold & Ring games. During the bonus, it doubles the value of every adjacent coin. On a 3x3 grid, a center Joker touches all eight surrounding positions. Corner placement still reaches three neighbors. That x2 applies to each coin individually before the final tally, so a Joker surrounded by 20x, 35x, and 50x coins turns those into 40x, 70x, and 100x. The Boost orb works its usual Zillion role too, summing nearby coin values into a single collected payout.

Purple grid lines glow against a dark neon backdrop - less classic fruit machine, more arcade cabinet. The symbols are standard fruit fare (cherries, lemons, grapes, plums, watermelon, oranges) alongside bells, BARs, and red 7s, but every icon has a faint electric outline that pushes the whole thing into cyberpunk territory. Bonus coins pulse amber against that purple grid, and the Joker himself grins in green and gold from behind a flaming border.
