Four Lucky Diamonds by BGaming — RTP 94.03%

Four Lucky Diamonds by BGaming has a theoretical RTP of 94.03%, which is below 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.

Four Lucky Diamonds is developed by BGaming. You can play it on Duel.com and other crypto casinos that carry BGaming 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.

Four Lucky Diamonds returns 94.03%, which is below 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 BGaming page lists every one we hold with its published return.

At 94.03%, Four Lucky Diamonds holds back about 1.97 more per $100 wagered than the average slot. That is the one number about this game that is genuinely known in advance — and there are titles on the same reels-and-features formula that give more of it back.

Four Lucky Diamonds returns 94.03%, below the industry average of 96.00%, so it costs more to play than the typical slot over the long run. That may be worth it for the game itself, but purely on value there are better-returning alternatives — our provider pages list them.
