Wrong declarations in Indian rummy are priced off a points sheet, and a common sheet charges a first drop at 20, a middle drop at 40, and a full count at 80. Houses differ, so those three numbers are a working example, not a promise that every client uses them. The example that matters is a hand that never held a pure sequence. The player has sets, an impure run that uses the wild, and no three natural cards in a row of one suit. Declaring that hand is not a close show. It is an illegal show.
One hand priced two ways
Walk the same deal both ways. Thirteen cards, no pure sequence, several draws already taken. If the player had left on the first turn, the common sheet would score 20 points to the winner. If the player instead presses show, the declaration fails and the common sheet scores the full 80. The gap on that one deal is 60 points. Nothing in the sets reduces it. The pure sequence was missing, so the other melds are not scored as a partial success. They are ignored, and the penalty is the full count.
Treat the sheet as common, then read the house
A first drop was available at the start for 20 on this sheet. Choosing to build sets around a wild and then declare converts that 20 into 80. Pool games can make the same 80 fatal, because 80 is most of a 101 pool. Points games settle the 80 in cash value for that deal and let you continue. Read the client’s own drop table before you apply 20, 40, and 80. If the house prints different drop scores, use the printed ones. The rule that does not move is the pure sequence: without it, the show is the full count, not a discounted drop.
