Ogwan is a patience game older Koreans played alone with hwatu cards to read their luck for the day.
- Shuffle the 48 cards and lay out 20 of them in five columns (the "five gates") of 4 cards each. The other 28 cards form the stock.
- Only the bottom card of each column and the top card of the waste pile are in play.
- Tap two playable cards of the same month one after the other to remove them together.
- If there is no pair, tap the stock to turn one card onto the waste pile. When the stock runs out, you may restack the waste pile once.
- Clear all 20 cards from the five columns to win. In Korea people would say the gates fell well that day.
The layout of Ogwan varies by family and region; this page uses the method above. This is not a gambling game.
