What is Sashikomi?
Sashikomi (intentional deal-in) is an advanced tactic where you deliberately deal into a specific opponent for strategic reasons. Usually done to manipulate rankings, especially in the final hand.
“Sashikomi” literally means “inserting” points - strategically feeding points to a chosen player for your benefit.

Summary
Sashikomi is intentionally dealing into someone to control rankings - an advanced endgame tactic. Used appropriately in close oorasu situations, it can be effective, but being too obvious is poor manners. Beginners should first enjoy normal mahjong and learn scoring, then consider this technique. Sashikomi should be a “last resort” used sparingly and naturally.
