Zillion Games

Many Zillion Games slots hinge on a re-spin round. Coins or Bonus symbols lock onto a small grid, the counter goes back to three whenever a new one lands, and the round lasts until it runs dry. The Zillion demos on this page cost nothing to open and need no sign-up, so you can compare how each game bends that round to its own rules.

Inside Zillion Games

Zillion Games is the trading name of Ziplay Limited. Its site carries an RNG certificate issued by iTech Labs on 25 January 2022 and says the studio supplies casinos across Europe, Australia, Canada and Brazil, in both regular and crypto currencies. The oldest Zillion game in our library, Leprechaun’s Gold, dates from July 2021, and the newest arrived in October 2026.

The studio’s awards page lists wins at the EGR Europe Awards in 2025 and the EGR Global Italy Awards in 2024, along with shortlistings for the SBC Awards Europe and EGR Europe Awards in 2026. It presents itself as a slot specialist, and the feature names it promotes most are the ones you’ll meet again and again below: Hold and Ring, Bonus Re-Spins, Gold Collect and Multichance Free Spins.

Slots and Formats

Re-spin coin games. Electro Strike, 3 Dragon’s Pots and 3 Buffalo’s Fireshoe have no free spins at all. Their bonus is a round of three re-spins that resets with each new symbol.
4,096 ways. Golden Lion: Wild Savanna, Buffalo’s Sun 2 and Zeus Fortune all play on a 6×4 grid and pay on adjacent reels from the left.
Smaller ways games. Magic Treasures has 1,024 ways on a 5×4 board, Candy Stash has 576 and Train of Fortune has 45.
Book games. Book of Magic and The Book of Valkyrie each run 25 lines, with one golden book acting as both Wild and Scatter.
Nine-cell games. Firestorm Joker, Cute Dragon and 3 Dragon’s Pots pay three of a kind on 5 lines across a 3×3 grid.
Cluster. Cluster Gems fills an 8×8 grid and pays for five or more touching symbols. It’s the only cluster game among the Zillion titles here.

Mechanics and Features

Zillion’s coin rounds share a frame and differ in the trigger. Train of Fortune stands a five-row reel between two reels of three and starts its Respins Bonus when Bonus symbols land on reels 1 and 3 with a BOOST symbol between them. Electro Strike keeps gold Bonus coins to its outer reels and gives the collector work to do in ordinary spins, then opens the Bonus Game once every reel shows a Bonus symbol. On the 3×3 games the round does more with less space. 3 Dragon’s Pots can add an extra row and double its Multi cells from x2 as far as x32, and Firestorm Joker’s Wild marks the cell it lands on at x2, climbing to x10 as more Wilds hit the same spot. Pharaoh’s Secret and Buffalo’s Sun 2 use the larger version, a round Zillion calls Hold and Ring, with a Grand prize in Pharaoh’s Secret for filling all 20 cells.

The big ways games set their free spins by Scatter count. Golden Lion: Wild Savanna and Buffalo’s Sun 2 both award 8, 15, 25 or 50 free spins for three to six Scatters. Zeus Fortune hands the decision to a Wheel of Fortune, which shows how many spins you’ve won, and its free-spin Wilds multiply by x2, x3 or x5.

The book games each add a twist to the usual formula. Book of Magic has a second book with a job of its own, and the Valkyrie’s three golden books open Multichance free spins. Cluster Gems goes its own way, removing winning clusters and raising a re-spin multiplier through x2, x4, x8 and x10.

RTP and Risk Level

None of these figures appears inside the games themselves, so the RTP, volatility and top prize for each demo come from Zillion’s own game pages. The returns sit in a fairly tight band, from 94.96% on Candy Stash to 96.20% on Firestorm Joker and Zeus Fortune. Most of the range is rated High. Firestorm Joker goes a step further at Very High, while Book of Spells and Candy Stash are the two Low-rated games.

Top prizes stay below 10,000x throughout. Electro Strike has the largest at 7,000x, followed by Train of Fortune on 5,615x, Buffalo’s Sun 2 on 5,268x and Firestorm Joker on 5,250x. The low-volatility Book of Spells stops at 785x. The interest in this range lies in how the features fit together more than in chasing a five-figure multiplier.
