Board Game Arena

I only know one way to do this: By setting the pairing order carefully in the game options. The default is random, but the other options are 1&2 vs 3&4, and 1&3 vs 2&4.

One advantage is it is fast to type (on a tablet or phone). It is frustrating when everyone leaves before I finish typing a longer message. Agreed it is sometimes a bit inaccurate.
