Naturally, this yaku is reasonable if your hand contains many triplets and/or pairs. Note that toitoi looks easier than it actually is. There are only 2 possible tiles that can turn a pair into a triplet - there are 4 copies of a tile in mahjong, and 2 are used in the pair, leaving 2 tiles that can make the pair into a triplet. Meanwhile, a [[ryanmen]] joint can be turned into a sequence with 8 possible tiles. While you have access to pon to turn pairs into triplets, your opponents might not discard the tiles you need to pon in the first place. The tiles could be in the [[dead wall]], or they could be used in | Naturally, this yaku is reasonable if your hand contains many triplets and/or pairs.

Pairs made out of middle tiles (tiles from 3-7) are particularly hard to pon. Because the middle tiles are likely to be kept in an opponent's hand, they are hard to pon. If you have multiple pairs made out of middle tiles, this yaku becomes slower to complete. | Pairs made out of middle tiles (tiles from 3-7) are particularly hard to pon.
