The more relics there are in the sarcophagus, the greater the reward you receive. The total value of the gods is multiplied by the number of relics. In addition, there is a combo system which adds an extra modifier on top of this, significantly increasing the reward.
That’s why individual relics contribute very little to progress, but as soon as they’re combined into a combo, the reward increases exponentially.
We’ve tried to preserve the concept of truly random chance, just like in the original Unfair Flips, that’s what makes success feel genuine, rather than rigged by the developers.
Maybe on your 699th attempt, you’d land a long combo and immediately max out your luck in the demo, or maybe, after a long streak of bad luck, you’d unlock all 12 relics at once and resurrect the mummy.
