The Scatter Symbol is what you’ll need to land to set off the Free Spins Feature in ‘Rainbow Jackpots’. If you manage to land three of them anywhere on the reels, the feature will immediately begin. When it all starts, you'll need to select one of three pots. Each one holds a different random number of free spins. Whichever one you choose will inform how many free spins you’ll begin the round with. The amounts available are five, six, eight, nine, ten, eleven, twelve, and fifteen. As an extension of this round, there is also a Mega Free Spins Feature. This can only be randomly activated by the lucky Leprechaun blowing his pipe and creating a Mega Free Spin Symbol. If this occurs, the number of free spins available increases significantly, moving up to thirty, forty, fifty, sixty, seventy, eighty, ninety, and one hundred.
