Bonanza is Big Time Gaming's gold-mining slot released in 2016, the original title that debuted the Megaways mechanic. Per the provider's own game page, it carries a 96.11% RTP, up to 117,649 ways to win on a 6x7 grid, and an official maximum win of 26,000x the stake. Its Megaways system has since been licensed to numerous other studios (including Pragmatic Play and others whose titles appear across the online slots market), making Bonanza the mechanical ancestor of a large share of modern high-volatility slots.

Verified facts about Bonanza
Official RTP: 96.11% (game page on Big Time Gaming's own platform, beta.bigtimegaming.com). Volatility: 37.94%, per the provider's own published metric. Maximum win: 26,000x the stake. Grid: 6 reels by 7 rows. Ways to win: up to 117,649 (Megaways system).
We were unable to confirm an official traditional-paylines figure, because the game does not use fixed lines — it runs on the Megaways ways-to-win system. Big Time Gaming's own platform is the primary official source for this title, distinct from the pragmaticplay.com and netent.com sources used for the other five games on this site — a reminder that "provider-verified" means checking each studio's own documentation individually, not assuming a shared format across providers.
Important: the RTP figure above is the studio-level figure published by the game's own provider. Slot providers commonly certify more than one RTP configuration for the same title (this is standard, documented industry practice across regulated US markets, not specific to Pennsylvania), and a PGCB-licensed operator may run a different certified configuration than the one shown here. Always check the live RTP disclosed in the game's own paytable or info panel (the "i" icon) inside the operator where you actually play — do not assume the provider's headline studio figure is the one running at every Pennsylvania casino.
What Megaways is, and how Bonanza plays
Bonanza was the first game to use the Megaways system, patented by Big Time Gaming: each of the 6 reels can display between 2 and 7 symbols per spin, variably, which multiplies the number of possible combinations up to a maximum of 117,649 ways to win on a single spin.
The game also uses cascading reels: after a winning combination, the involved symbols disappear and new symbols fall in, allowing chained wins within the same spin. The bonus round triggers by spelling out "GOLD" with scatter symbols: four scatters award 12 free spins, and each additional symbol adds 5 more spins. During free spins, the win multiplier increases with each cascading reaction, with no declared per-spin cap, according to Big Time Gaming's own mechanic description.
RTP and volatility: the Big Time Gaming figure
The 96.11% RTP is, per Big Time Gaming, the official figure for this title, slightly different from the 96.00% figure repeatedly cited by numerous third-party sites — we chose to publish the figure that appears directly on the provider's own official game page, verified 06/07/2026, rather than the more widely circulated aggregator figure.
The 37.94% volatility figure corresponds to the numeric metric the provider itself publishes on its game page (a number, not a text label like "high/low"); combined with a 26,000x maximum win, the mathematical design aligns with what the industry commonly describes as high volatility, though Big Time Gaming does not use that specific text label on the page reviewed.
How Bonanza compares to the other titles on this list
Bonanza's 26,000x maximum win is the highest of the six titles covered on this site, narrowly ahead of Sweet Bonanza's 21,175x and well ahead of the much lower-volatility Starburst at 800x. It is also the only title here that uses the Megaways ways-to-win system rather than fixed paylines, cluster-pays, or hold-and-win mechanics — the closest structural relative among the other five is Gates of Olympus's pay-anywhere cluster system, since both generate a large number of possible winning combinations from a compact grid, but the underlying mathematics (variable reel heights vs. fixed cluster matching) are distinct.
For a player comparing raw ceiling potential across all six games, the order from lowest to highest confirmed maximum win is: Starburst (800x), Wolf Gold (1,000x confirmed on the Mega Jackpot symbol only, aggregate unconfirmed), Sweet Bonanza (21,175x), Bonanza (26,000x) — with Gates of Olympus and Big Bass Bonanza's aggregate maximum wins unconfirmed in official documentation, so they are not placed on this ranking.
Availability at Pennsylvania online casinos
We have not been able to confirm this specific title against any PGCB-licensed Pennsylvania operator's own official game library. Operator game libraries are JS-rendered, require a live account, and are geo-gated to Pennsylvania IP addresses, which means a remote verification pass cannot confirm a live title list without hands-on access from inside the state. Third-party listings claiming a given casino carries this game are common online, but we do not treat those as sufficient sourcing under our verify-gate policy — only an operator's own official library or an official provider/PGCB source counts. This does not mean the game is unavailable in Pennsylvania; it means we have not yet verified it against a source that meets our bar.
The most reliable way to confirm whether a specific PGCB-licensed casino carries this title today is to log into the operator's own account (a free account is typically enough to browse the lobby, even before depositing) and search the slots library by name or by filtering on the provider. Because operators periodically rotate their catalogues — adding new releases, and occasionally dropping older ones as content deals change — a listing we could verify in the past would not necessarily still be accurate today, which is another reason we do not carry forward a stale claim rather than re-verify it. If you cannot find the exact title inside one operator, checking two or three PGCB-licensed casinos in turn is a quick way to build your own current shortlist; see our Pennsylvania casino reviews for the full list we track.
