How do I check the build myself?

Open the game, then the paytable or info screen. The return is stated there for the configuration you have loaded. If it differs from the published figure above, tell us and we will add it to our RTP Watch queue.

Is the max win realistic?

It is real but rare. Treat it as the tail of the distribution, not a target — the median session ends nowhere near it.

Bonanza Megaways: 96.00% published RTP, 26,000x max win

Bonanza Megaways is a Big Time Gaming title with a 26,000x max win and a published return of 96.00%. Operators can legally ship a reduced-RTP configuration of the same title without disclosing it in the lobby, so the paytable in the game's info screen is the figure to trust.

Questions readers ask

We haven't field-tested a per-operator build for this title yet. Until we have, treat the published return as the ceiling, not a guarantee at any specific casino.

Bonanza Megaways: our verdict

Big Time Gaming's gold-mine slot, its own Megaways reel set paired with cascading symbols: up to 117,649 ways, a published 96.00% return and a 26,000× ceiling.

Why it is on the list

Bonanza is Big Time Gaming's pairing of Megaways with cascading symbols, which the studio's page calls another world-first innovation. Big Time Gaming's own page describes it as building on the studio's patented Megaways system, giving each spin up to 117,649 ways to win, combined with cascading symbols. That pairing is the reason it is still on the list: a variable reel set where every win clears space for another chance in the same spin.

How it plays

Big Time Gaming's page is short on rules. It confirms the Megaways reel set, the 117,649-way maximum, cascading symbols and a Wild West gold-mine theme, and it lists the game for mobile and desktop in HTML5. It does not set out the free spins, multipliers or special symbols, so we do not describe them here; the studio's own demo, linked from the same page, shows the full feature set before you stake anything.

The maths

Big Time Gaming publishes one return on its game page: 96.00%, with no statement on lower builds, so the paytable inside the game is the place to confirm yours. Max win is 26,000× the bet, the highest ceiling in this batch. The studio does not publish a volatility rating, so we print none either; the upside depends on long cascade chains across a reel set that changes size on every spin.

Who it is for

Players who want the original version of a format they may already know from its imitators, and who are comfortable with long quiet stretches between the spins that matter. If you want a cascading Megaways game with a multiplier you can watch climb, Gonzo's Quest Megaways, on this list, runs to 15× in its Free Fall round at a 20,972× cap.
