Understand the Sapaw Mechanic from the Start
Tongits is a three-player draw-and-discard card game where the goal is to reduce your hand points to zero or as low as possible. Sapaw happens when a player lays a meld — a valid set or sequence — on top of another player's exposed meld on the table. To Sapaw, your added cards must form a complete, legal extension of that meld.
You can only Sapaw on an existing tableau meld, never into a player's hand. Each Sapaw reduces your hand count directly, so timing it right against another player's strong meld can shift the round completely. Points are totalled from remaining hand cards when the round ends by draw exhaustion, a Tongits call, or a successful Fight challenge.
