The Flower Power symbol acts as a ‘joker’ and stands in for any other symbol to complete a winning combination along an active payline(s).

Some examples:

A single Flower Power symbol on a payline will complete the winning combination if the correct symbols are present. 

So if a 1-Bar and a 2-Bar appear on the payline with a Flower Power Symbol this will complete a 3 Any-Bars payout paying 7 coins.

Similiarly if two Peace Symbols appear on the payline with a Flower Symbol this will complete a 3 Peace Symbol payout paying 300 coins.

2 Flower Power symbols and a 3-Bar on the payline will combine to produce 3 3-Bars on the payline that would pay out 80 coins. 

And so on...
