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