The Lock & Win feature is triggered when three or more Lantern icons appear in the reel. All Lantern icons appearing in the unlocked reels remain at their place till the feature is completed. If the Bamboo Forest icon appears in an unlocked reel, it expands the reel and increases the prize value of the adjacent Lantern icons. The remaining Free Spins reset to 3 if a Lantern icon appears in an unlocked reel during the spin.
