The Si Ling feature is triggered by 6 or more Scatter symbols anywhere on reels during the main game round. To start the Free Games round, a player needs to pick 1 out of 4 or 1 out of 5 Free Games modes. Each mode contains varying number of free games and a different stacked symbol. The stacked symbol is stacked on all reels throughout the Free Games round. The mode with 11 free games has the lowest value picture symbol stacked; the mode with 5 free games has the highest-value picture symbol stacked. There is also a 5th mode called the Random Super Choice, which can randomly appear within the Si Ling feature. This mode has 3 free games and the highest value stacked symbol – the Wild symbol. The Si Ling feature can be re-triggered during the Free Games round.
