Finishing on the okey is worth double because going out with the game's most powerful joker is treated as a bonus achievement.

The okey completes any group, so building a winning hand and then discarding the okey as your final tile earns twice the normal score. This reward encourages bold play, since holding the joker until the very end is riskier than using it early. Combined with the seven-pair route, which also pays double, it gives skilled players extra ways to maximise a single winning hand.
