Game introduction

The "Ox values" of the cards are as follows:

  • Ace = 1
  • 2,4,5,7,8,9 = respective face values
  • 10,J,Q,K = 10
  • 3 = 3 or 6
  • 6 = 3 or 6

Ranking of Oxen

Here shows the ranking of oxen from lowest to highest:

  1. No Ox: Player is unable to form an Ox, that is no 3 cards sums up to multiple of 10.
  2. Ordinary Ox: ranked by the sum of the other 2 cards (if the sum is greater than 10, take the remainder after subtraction of 10)
  3. Double Ox: if the other 2 cards are equal in face values (not Ox values). ranked by the face value of the double.
  4. Ngau Tonku: if the other 2 cards having Ace spade & picture (J,Q,K). If the Ace is others, that is called nenku and only count as 1.
  5. Five Dukes: if all five cards contain only face cards (J, Q, K).

Example:

  • Cards in hand: 3,6,8,4,8
    • 3(counted as 6) + 6 + 8 = 20, 4 + 8 = 2 (take remainder)
    • 3 + 6(counted as 3) + 4 = 10, 8 + 8 = Double-Ox Eight
    • 8 + 4 + 8 = 20, 3 + 6 = 9
  • If one gets cards with face values 6,4,J,9,9 It's a Double-9 Ox.
  • If one gets cards with face values K,J,Q,Q,K It's a Five Dukes.
