Brainy Go:okey bulmaca

BrainyGo: Okey is a single-player, casual puzzle game based on Okey tiles. Each level gives you 1 almost completed hand, but the tiles in your hand are still scattered. In each turn, you can choose 1 to 3 tiles and then replace them one-to-one with the same number of invalid tiles in your hand. This is not a test of luck or skill, but rather a test of observation, reasoning, prediction, and decision-making. Find the most opportune moment to exchange the cards and turn a scattered tile into a complete answer.
