Expanding grid

The grid gains rows or reels when a feature starts and keeps them until it ends, so the number of ways to win inside the feature is larger than in the base game. This is not the same as a grid that resizes on every spin and never keeps its size.

What it does to your session

Written once for this mechanic, not per title.

Moves value into the feature and out of ordinary play, which raises volatility and makes the round the game is really about.

Also called

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

Growing Reels · Reel Growth · Expanding Reels · Reel Expansion · リール拡張 · 扩展转轴

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.
