About Gamzix
Gamzix was founded in 2020 and is based in Warsaw. The studio has grown around mobile-friendly video slots, modern versions of familiar casino themes and operator tools such as tournaments and promotional features. Gamzix states that its catalogue exceeds 60 games and that its content reaches more than 2,000 casino partners. It also holds an MGA B2B supplier licence.
Its Bonanza contribution is currently a tightly connected pair: Bonanza Donut and Bonanza Donut Xmas. The Christmas release is a seasonal edition of the same underlying product rather than an independent slot.
Clusters, cascades and donut multipliers
Both games use a 6x5 cluster-pays screen. Matching symbols need to connect in groups rather than fall across fixed paylines. Every winning cluster disappears through a cascade, leaving room for replacement symbols and possible consecutive wins from one paid spin.
The donut is the defining special symbol. During free spins it can apply a multiplier between 2x and 100x, giving the bonus substantially more potential than an ordinary base-game cascade. Four or more scatters activate the free-spin round.
A second layer appears after enough ticket symbols are collected during free spins. This triggers a pick-and-win bonus in which the player chooses from five concealed boxes. The selected prize supplies an additional multiplier to the free-spin win. I like that this breaks up the cascade routine, although the pick itself is a presentation of a random result rather than a skill decision.
| Game | Default RTP | Maximum win | Material difference |
|---|---|---|---|
| Bonanza Donut | 96.20% | 13,000x | Original confectionery theme |
| Bonanza Donut Xmas | 96.20% | 13,000x | Christmas artwork and presentation |
Alternative RTP configurations
Gamzix publishes three return settings for both editions: a 96.20% default, plus 95.16% and 94.25% alternatives. This is more transparent than leaving the lower configurations undocumented, but players still need to open the help screen at the casino. A review showing 96.20% does not prove that every operator has selected that version.
The maximum win is listed at 13,000x the stake. Reaching that ceiling would require an exceptionally favourable combination of clusters, cascades, multipliers and bonus events. It should be treated as a mathematical limit, not a representative target for a normal session.
Gamzix also offers Hot Bet and a feature-purchase route in supported markets. Hot Bet changes the cost or probability profile of the game, while Buy Bonus provides direct access to free spins. Neither option removes the house edge, and both can make a bankroll move much faster than standard spins.
A real series, but not yet a broad one
Bonanza Donut is a properly assembled slot rather than a title carrying the keyword without relevant gameplay. It has clusters, cascades, multipliers and a high-potential bonus, all features players now associate with the category. The ticket collection and pick round add at least one identifiable Gamzix detail.
However, Bonanza Donut Xmas is primarily a seasonal reskin. The same 96.20% default RTP, 13,000x ceiling and feature list confirm how little the mathematical identity changes. I would choose between them on presentation alone; there is no convincing gameplay reason to treat the Christmas edition as a sequel.
The bigger question is whether Gamzix will turn Donut into a wider experimental family or continue producing calendar-based skins. At present, I regard it as one genuine Bonanza game with two visual editions, not two separate contributions to the genre.
An MGA B2B licence concerns the supply of games and does not establish that an operator may offer online casino play to Australian residents. Australians should verify the operator and local restrictions separately. These high-volatility games are entertainment with a substantial risk of losing the full stake.
