Server cap is 6 players
Karinderya supports up to 6 players per server. The Shift Simulator multiplies arrival rate by 1 + (0.18 × (party_size - 1)) so a 6-player server sees ~1.9× the single-player traffic.
Divide roles
Assign each teammate a station: one cook, one server, one seat-assigner, one register screener for high-runoff NPCs. Bottlenecks appear when two teammates double up on the same station.
Potions are per-player
Cash Potion (1.5× Cash) and Luck Potion (-10pp walkoff) are personal buffs; coordinate so the Cash Potion lands on the shift where you expect the highest revenue, not the shift with the most walkouts.
