-The term is often confused with the "fifth tile" case.  Here, a hand waiting for a fourth tile that is simply hidden, discarded, or used by someone else remains a valid tenpai in all circumstances. A hand containing a 1-2 [[Penchan|penchan]] and a previously declared [[Kan|kan]] of 3-3-3-3 in the same suit, no more threes are available as winning tiles. Because of the prevalence of '''keishiki tenpai''', it is assumed that if the rule is different, it would be announced what qualifies as tenpai or not. As a precaution, it is almost always mentioned.
