A 2-player game (not exceeding one hour) ends the moment one of the two players loses their last life, and the score taken is the sum of both player's individual scores at that point -- in the case of Space Duel, the game in 'tethered' mode actually displays 'Combined Score' and also kills off both players simultaneously
Tournament scoring is by rank, not percentage-based; e.g. with four teams of 10 players, a first place score on a single-player game will earn 40pts.
The Overall Scoreboard will sum team totals from the Single-Player Scoreboard and the 2-Player Scoreboard
Team totals from the Single-Player Scoreboard will be summed from the top 10 qualified players from each team
Team totals from the 2-Player Scoreboard will be summed from the top 5 pairs from each team
Tournament points are worth quadruple for 2-player submissions; e.g. with four teams of 10 players, 5 pairs per team, a first place score on a 2-player game will earn 80pts. (4 x 20pts.)
To qualify for the Single-Player Scoreboard a player must submit scores for all 10 single-player games
To qualify for the Single-Player Scoreboard team totals a player must be ranked within the top 10 of their team, inclusively
Players are not required to submit for the 2-player games to qualify for the Single-Player Scoreboard
Players are not required to qualify for the Single-Player Scoreboard to submit for the 2-player games
A player may be partner in only one 2-player pair submission per 2-player game -- players are free to mix and match their partners and play with multiple partners per 2-player game, but previous scores will be overwritten if even one of the pair is duplicated in another submission for the same 2-player game
All scores must be submitted before tournament end.
