Slots with expanding reels change the size of the grid during play. More rows mean more ways to win, so the change reaches every spin that follows. Games differ in when the grid grows and how far.

Two ways to grow a grid

Triple Beasts of Fortune grows once per round. Its Expand free spins add two rows, which takes the grid from 1,024 ways to 7,776. Primal Rampage changes the grid on every spin of Kong Quest, picking a size from 3×3 to 3×8, or from 27 ways up to 512.

Which one to open

If you like a steady, predictable grid inside a round, start with Triple Beasts of Fortune. If you want the size to keep changing, Primal Rampage is the one. Both pair the idea with Ways to Win.
