Colossal Gems

Colossal Gems (Colossal Gems) is a space-themed 6×5 reel, 30 payline slot. When you win, respins follow and symbols grow larger – that’s the core feature, with free games also included. You can try the free demo with no sign-up required.

How do respins work?

In Colossal Gems, any win grants a respin. Each winning spin gives you another chance to spin, so every spin’s flow feels connected. As these respins continue, the symbols on screen keep growing larger. The game description even highlights that wins lead to respins and increasingly bigger gems.

How much do the symbols grow?

Larger symbols appear based on the respin order. On the 1st respin you get 2×2 symbols, on the 2nd you get 3×3, and on the 3rd you get 4×4 symbols guaranteed. Being able to see increasingly bigger gems as consecutive wins pile up is the fun payoff of this game.

When do free spins start?

If 3 respins of wins land in a row, you’re awarded 6 free games. So keeping the respin flow going unbroken matters. During free games, a Colossal Gem appears at least once per spin. It’s a section where you encounter large symbols often, so definitely check it out in the demo.
