The dead wall removes the possibility of "tile counting" since what tiles taken out of the game are random. This isn't the case in other variants which go until all tiles have been exhausted from the wall.

If I recall correctly,

136 tiles
-14 tiles (dead wall)
-13 tiles x 4 (deal)
=17 rounds of 4 draws each.
=2 extra draws at the end

So if there are no calls, the game goes for 17.5 rounds, ending at the South House.
