When it comes to the free spins feature in Opal Fruits, players will need to land four of the scatter symbols across the reels that spell out the word FREE. These golden scatters will then trigger the 10 free spins, where players can unlock a 1x multiplier. However, if more scatters appear on the reels, either five or six, it will award the same amount of free spins but with a 5x or 10x multiplier. The free spins feature can be retriggered when the multipliers increase by 10x and by landing additional scatter symbols.
