Can multiple players be eliminated simultaneously in a multiplayer game?

In multiplayer games, state-based actions are checked and applied simultaneously across all players. If multiple players meet a losing condition at the same moment — such as having 0 or less life, drawing from an empty library, or having ten or more poison counters — they are all eliminated at the same time. This is governed by CR 800.4, which covers player elimination in multiplayer games, and CR 704, which covers state-based actions applied simultaneously.

Simultaneous elimination is especially relevant for determining winners. If all remaining players are eliminated at the same time, the game is a draw rather than any single player winning (CR 800.6). Conversely, if a single player remains after simultaneous eliminations, that player wins.

Triggers and effects that refer to a player being eliminated will see all simultaneously eliminated players as having left at the same time. This matters for cards or abilities that trigger 'when a player loses the game.'

Concrete example: In a four-player game, players B, C, and D all have 1 life. Player A casts a spell dealing 2 damage to each opponent. State-based actions are checked: B, C, and D all have 0 or less life simultaneously, so all three are eliminated at the same time. Since only Player A remains, Player A wins.

Note that if players are eliminated due to a player leaving voluntarily or a specific card effect that targets them individually in sequence, they may not be considered simultaneous — the exact mechanism matters. But standard state-based action checks eliminate all qualifying players at once per CR 704.3.
