Mechanic in focus: the multiplier ladder
The Fortune Gems family is defined by a visible multiplier ladder — a rung that steps up as wins chain and, in the feature, can persist and climb. Unlike the Ace family, which hides its multiplier inside expanding wilds, the Gems ladder is out in the open, which makes it a clean example for understanding how a persisting multiplier front-loads the value of a bonus round.

Catalogue spotlight
From the titles documented on this site, three worth a look through the multiplier-ladder lens:
| Title | Family | Why it is on the list |
|---|---|---|
| Fortune Gems | Gems ladder | The clearest example of the persisting-multiplier idea |
| Fortune Gems 3 | Gems ladder | A re-tune of the same skeleton — good for spotting what changed and what did not |
| Super Ace | Ace wilds | The contrast case: a multiplier hidden inside wilds rather than shown on a ladder |
Everything here is reference material. We list no operator, take no stake and recommend no bet — the house edge is unchanged by any mechanic in focus this week or any other.
