All triplets 対々和 · toitoihou
A hand of four triplets (or kans) and a pair — no sequences at all.
| Value | 2 han, open or closed |
|---|---|
| How often | common |
Toitoi starts from a pair-heavy deal: four or more pairs and few connected shapes. That is a weak hand for sequences and a strong one here, since every pair is a pon ポン waiting to happen. If your pair count reaches four in the first few turns, toitoi is often the natural line.
The craft is in which pons you take. Call value tiles and pairs that opponents are discarding freely, but if triplets are arriving from the wall on their own, wait: three concealed triplets add sanankou for 2 more han, and a hand that stays fully concealed is on the road to suuankou, a yakuman. The classic mistake is the opposite reflex, calling every pair on sight and reaching tenpai テンパイ with a thin final wait the whole table can read.
Toitoi also pays in fu 符: triplets, especially concealed ones of terminals and honors, raise the base score quickly, so check the fu page before writing the hand off as small. The cost is flexibility — with three melds down you hold four tiles and have little left to fold with, so call because the hand is live, not just because the pairs exist.
Key points
- Full 2 han even when open — the classic pon-heavy strategy
- Pairs naturally with yakuhai triplets and sanankou
- Watch the fu: triplet-heavy hands often score higher than their han count suggests
