Khmer is a simple card game for two players. There are only 16 cards and the game takes 20 minutes for 6-point match. Your goal is to have a hand with higher total value than your opponent. However, the cards on the table decides the maximum value. If your hand has higher total value than the cards on the table, then you cannot win.
In your turn, you either:
1: play a card from your hand to the table,
2: draw the top-most card from the table and add to your hand,
3: discard a 6 from your hand, or
4: knock to see who wins.
The game is extremely short and it is recommended to play 6-point match (each game worth 2 points and folding gives 1 point to the opponent).
