Difficult Ways to Win Doubles
Whole hand consists of pungs or kongs (no chows).
You get one extra double for every concealed pung/kong after the first: none concealed = 1 double, 1 concealed = 1 double, 2 concealed = 2 doubles, 3 concealed = 3 doubles, 4 concealed = limit
Whole hand concealed (you took no tiles out of turn, with the possible exception of your winning tile) 1
Honors and terminals in each combination (chows, pungs, or kongs) and the pair 1
Clever Reversals Doubles
No points in hand (all chows, pointless pair; doesn't count flowers or extra points for winning: Mahjongg, winning tile drawn from wall, one-shot, or "fishing the eyes") 1
Whole hand consists of simples (no honors, no terminals) 1
Pure Luck (very rare) Doubles
"Catching the moon from the bottom of the sea" - win on last tile drawn from wall 1
"Catching fish from bottom of river" - win on last discard after living wall exhausted 1
"Plum blossom on the roof" - win on draw from Kong box 1
Robbing a Kong - stealing tile that would make a kong from an exposed pung 1

The limit for any hand is 500 points. If doubling would raise a score higher than 500, it is capped at 500.
