How does the 50 Lions slot bonus feature work?

Three Protea flower symbols on Reels 1, 2, and 3 triggers 10 free games.  During each free spin, an extra wild DIAMOND symbol is added to Reels 2, 3, 4, and 5. This also creates a ‘Stacked’ effect, although now you are getting a Wild symbol that is being stacked.  

The Wild Diamonds now stack themselves generating multiples line wins on any symbol.  Think about it: by the end of Reel Spin 10 during the bonus feature free games, there are 40 WILDS added to the reels. Get more details at http://www.slotreviewonline.com
