Forbidden Alchemy by PG Soft — RTP 97.76%

Forbidden Alchemy by PG Soft has a theoretical RTP of 97.76%, which is above average for online slots. This is the figure the game's maths returns over its full lifetime, certified by an independent testing lab — not a reading from recent play.

There is no honest way to answer that, and we would rather say so than invent a number. Reading a single slot's actual return to within a percent takes tens of millions of spins on that one game, because one large hit outweighs weeks of ordinary play. Any site quoting you a slot's "RTP today" is quoting noise. What we do publish, where our tracker has recorded enough real bets, is how often the game pays at all — a figure that settles far faster and is shown on this page with its confidence interval.

Not in any way you can use. We tested our own recorded bet series for the serial correlation a genuine streak would leave behind, using Ljung-Box autocorrelation tests, and found none — the results are indistinguishable from independent draws, which is exactly what a certified random number generator is meant to produce. A game that has paid well recently is no more and no less likely to pay on the next spin.

Forbidden Alchemy is developed by PG Soft. You can play it on Duel.com and other crypto casinos that carry PG Soft titles. The game's maths is identical wherever you play it — operators cannot change a certified RTP, though some games ship in several certified versions and an operator may choose which to run.

Forbidden Alchemy returns 97.76%, which is above average for the industry (average 96.00%). The spread within a single studio is usually wider than the gap between studios, so it is worth comparing title by title — our PG Soft page lists every one we hold with its published return.

Forbidden Alchemy keeps 97.76% on the table over the long run — about 1.76 more per $100 wagered than the typical slot. That edge is small per spin and compounds only over very long play, but unlike anything you can read off a single session, it is real and it does not change.

Forbidden Alchemy has a theoretical RTP of 97.76%, which puts it among the better-value slots available — the house keeps less of your stake here than on most titles. That is a genuine advantage, though a modest one: it shows up over tens of thousands of spins, not over an evening. Everything else about whether to play it comes down to whether you enjoy the game.
