Okey is a card event with a fixed window, and it is not the Monster Card System topic already on this board. Monsters drop Okey Collectable Cards while the event is active, 24 cards convert into one Okey Card Set, and you spend those sets on the card game for chests. When the event ends, the cards and card sets are deleted.
When it runs
The wiki's summary box lists the summer event as running from 08-09-2026 0:00 to 01-10-2026 23:59. It is available for players above level 70, and the card drop ends one day before the event ends. There is a summer and a winter edition, and the wiki says the only difference between them is the interface and the reward chests.
How a round works
Open the Event UI with CTRL + E, press start, pay 30,000 Yang, and give 1 Card Set. Five random cards appear on the field. You must select 3 cards that are either 3 identical numbers with different colours, or 3 ascending cards with different or mixed colours, and there can be no gap between the selected cards. If nothing on the field fits, right-click to throw one out. The wiki notes a "secured" setting in the Event UI that warns you before a card is deleted when it is toggled on.
The points table
- Three identical numbers score 20 to 90 by number: 1s give 20, 8s give 90.
- Three ascending cards in the same colour score 50 to 100: 1-2-3 gives 50, 6-7-8 gives 100.
- Three ascending cards in mixed colours score 10 to 60: 1-2-3 gives 10, 6-7-8 gives 60.
The game ends when all 24 cards are used or you click End. The wiki's reward tiers are 299 points or less for a Bronze Okey Chest, 300 to 399 for a Silver Okey Chest, and 400 points or more for a Golden Okey Chest. The winter edition uses the same score bands with Merry Bronze, Merry Silver and Merry Golden chests.
The leaderboard prize
A top-10 finish on the Okey Table at the end of the event pays extra. Rank 1 gets 10 Golden Okey Chests, rank 2 gets 5, rank 3 gets 3, and ranks 4 to 10 get 1. The Okey Table also shows the highscores, and the wiki links to it from the event page.
Getting cards
Monsters drop Okey Collectable Cards during the event, and they are gathered in the Event UI. Twenty four cards convert into one Okey Card Set, and you can hold a maximum of 999 Card Sets. Three boxes are sold in the Item Shop while the event is active: Bronze Okey Box (9 DC), Silver Okey Box (19 DC), and Golden Okey Box (89 DC).
