Card order
3 is lowest, 2 is highest. Suits break ties (♣ < ♦ < ♥ < ♠).
Plays
Singles, pairs, triples, four-of-a-kind (bombs), runs of 3+ different ranks, sequences of pairs (3+). 2s cannot be in a run.
Turn
Holder of 3♣ leads. Each player either beats the previous play with the SAME shape (higher card), or passes. Round ends after 3 passes; last leader plays freely.
Bombs
A four-of-a-kind beats any single 2 or pair of 2s. Three consecutive pairs beat a single 2; four beat a pair of 2s.
Settlement
First to empty hand wins. Per-card-left penalty multiplied by the room entry; winner takes the pool minus a 10% platform fee.
