About Alchemist Bonanza
Released on 29 August 2022, Alchemist Bonanza belongs to BGaming's Bonanza line — 21 games in our database share the same payment rule. There are no paylines: symbols pay wherever they land on the screen, and the total count of matching symbols on screen determines the value of the win. The grid runs 6 reels by 5 rows according to SlotCatalog, so 30 positions; BGaming does not publish that format on its own page.
The Refilling Reels mechanic chains wins within a single spin: winning symbols disappear, the ones above drop into the gaps, and the sequence restarts for as long as a new combination forms. BGaming states no limit on consecutive refills. Hold on to the word "sequence" — it becomes central below.
Free spins follow a strict published scale: 4 scatters anywhere award 10 spins, 5 scatters 20 spins, 6 scatters 30 spins. If 3 scatters land during the round, 5 extra spins are credited. So four scatters is the minimum to open the feature — a high bar, and this is where the most telling number on the sheet comes in.
BGaming publishes an FS Rate of 398. That number describes how rarely free spins trigger naturally, and it reframes the whole game: at a €1 stake, reaching the feature without buying it means putting through something in the order of €400 on average; at €0.20, around €80. Against that, the hit rate of 2.59 describes a base game handing out small wins regularly. In other words: it pays often, it almost never opens up.
All the value therefore concentrates inside the free spins, because of one precise rule. A multiplier symbol appears only during free spins, never in the base game. When it lands it takes a random value from 2x to 100x and stays on screen until the current refill sequence ends. Then comes the crucial part, in BGaming's own words: when the sequence ends, "the value of all multiplier symbols on the screen are added together and the total win of the sequence is multiplied by the final value." They add, they do not multiply against each other — but they apply to everything the sequence produced, not to a single win. Three symbols at 20x, 50x and 100x give 170x across the whole total. That is the mechanism that makes the ceiling reachable.
The official RTP is 96%, meaning €4 of house margin per €100 staked over a very large number of spins. That is below the 96.54% average across the 227 BGaming titles in our database and below the 96.79% median. Nineteen studio titles carry exactly 96%, among them Bonanza Billion, Aztec Magic Bonanza and Wild West Bonanza. The 10,200x ceiling is not original either: Aztec Magic Bonanza, Izzi Art and Doddy And Haddzy Bonanza stop at the identical figure. Thirty-two catalogue titles reach 10,200x or more.
Two buttons complete the picture. Chance x2 slightly increases the stake to improve the odds of catching 4 or more scatters in the base game — that is the studio's own wording. The bonus buy triggers the free spins round directly, at a price shown on the button that BGaming does not publish on its spec page. One last point deserves flagging: the studio states a maximum win of €255,000, yet 10,200x a €20 stake — the maximum recorded by SlotCatalog — only comes to €204,000. The two numbers meet at a €25 spin. The sources are not aligned here.
