Multiplayer games
Bring someone else. Same keyboard or across the wire.
Everything here can be played with another person. Most of it works by code: one player opens a room, the others type in the short code, and the SyphonGames server keeps everyone's game in step and the score honest. That covers Greenside, 8 Ball Billiards, Syphon's Ten Pin, Syphon's Neon Air Hockey, Road Riot, Syphon's Slap Arena, trading and battles in Keepsies, and the tables in Syphon's Blackjack and Syphon's Texas Hold'em. Pinball takes turns for two players and Bankshot seats up to four on one screen.
The bigger rooms hold more people. Chaos Island and Tall Tails take up to eight players, Contrail Cup races up to eight pilots, Camp Kindling keeps a camp for up to six counselors and Little Bubbling shares a town between four brewers. Packfall and Pulsar League will also find you a public match, filling any empty places with bots. None of it needs an account; a display name is all a room asks for.
