Symbol upgrade

A symbol on the grid is marked, and winning with it promotes it to a higher tier, either once per feature or progressively as a counter fills, sometimes ending as a Wild.

What it does to your session

Written once for this mechanic, not per title.

Makes a long feature meaningfully better than a short one, which rewards retriggers and lengthens sessions.

Also called

The names other studios and other sites use for the same thing.

Symbol Level Up · Upgrading Symbols · Promote Symbol · シンボルアップグレード · 符号升级

These resolve to this one entry. A studio’s trademark for a mechanic does not create a second mechanic, which is why a search for any of these names lands here.
