Keep your eyes peeled for the Mad Mad Monkey logo as you play. This scatter symbol triggers 10 free games when 3 or more land anywhere on the reels. During the feature, the dark, night-time jungle background is replaced with a bright and sunny day-time setting, that is filled with vibrantly coloured flowers, leaves and butterflies. When the free spins are unlocked, you will see that stacks of banana symbols are added to the reels, in addition to the stacked wilds. Plus, every win in the free games is multiplied x3.

Be warned players, the free games are not frequently triggered. You may need to play for extended periods before you hit the elusive feature. Yet when you do crack them, you will not be disappointed. Thanks to the triple payouts, you can amass some big wins. Plus, given that the highest valued symbol, the banana also appears stacked, there are even more opportunities to stack up impressive wins. The feature can also be re-triggered by landing a further 3 scatters.
