This bonus it can be triggered when the Pinata symbols lends anywhere on the reels, but let's not forget that this feature The Pinata also act like a wild symbol, which substitutes all the symbols on the reels except from the scatter ones and that would be the Roses. But lending 3 or more Pinata symbols then you got the bonus round. When the bonus round opens it will give you 3 stages of the bonus, meaning you will break 3 pinatas and then go to another bonus rounds, which they are 3 stages total, till you got empty pinata, then the bonus round it's finished.
Of course the free spins is nice bonus but what I don't like about this feature is that you have to have 3 Roses and they can be from left to right or from right to left, but they have to be triggered in order, like on reels 1, 2, 3 or on 5, 4, 3 and on this game you will notice, they would be plenty Roses landing but not in that order, so free spins feature is hard to get. I been playing this game, many, many times for real money and also on free rools tournaments on the WGS casino, which they have each day tournaments and each day a new game is listed to play. I like playing this game, even if the free spins feature is hard to get, but the bonus round is here so, and it's easy to catch.
