Playing online with friends
Updated 16 October 2026
Sixteen of the games here can be played online with friends, and none of them needs an account. This guide explains how room codes work, lists which games support what, and covers the rules that keep online play friendly.
Room codes, not accounts
Online play on SyphonGames works the way it does at a games night. One person opens a room and gets a short code, usually four letters or numbers. Everyone else types that code into the same game and they are in. There is no sign-up, no friends list and no profile to fill in: the code is the invitation, and a room only ever holds the people who were given it.
In most games the option is called Play a Friend, Play with Friends or Multiplayer. The person who opens the room reads out the code; the others choose to join and type it in. Codes avoid characters that are easy to confuse, such as 0 and O, so they can be read aloud or copied from a screenshot.
Which games, and how many players
Two players, head to head
- Greenside: the same nine holes of golf, shot for shot.
- 8 Ball Billiards: alternate visits on the same table, with the server keeping the score.
- Syphon's Neon Air Hockey: first to seven, in real time. Best against someone in the same part of the world.
- Road Riot: the same generated road, raced side by side.
- Syphon's Slap Arena: play a friend with a code, or Play Online against whoever is around.
- Keepsies: link trading and link battles between two players.
Small groups
- Syphon's Ten Pin: up to four bowlers, alternating frames.
- Syphon's Blackjack and Syphon's Texas Hold'em: open a table and deal your friends in. Computer players fill the empty seats.
- Little Bubbling: up to four people sharing one town, one bank and one business.
- Camp Kindling: up to six counselors keeping one fire alive. If the host leaves, someone else takes over.
Bigger rooms
- Chaos Island: up to eight on a Survival Tour, with computer rivals filling any empty places.
- Tall Tails: up to eight anglers on the same water, with fishing competitions run by the host.
- Contrail Cup: two to eight pilots, in a private room or a public race.
Matchmaking
- Pulsar League: Play Online finds a public match and fills empty seats with bots after a minute. A party code keeps friends on the same team.
- Packfall: queue for a battle where bots fill the places nobody has taken, or create a duo and queue with a friend.
Our game guides cover several of these in depth, and the multiplayer category lists every game with any kind of play together, including two-player games on one keyboard.
Public matches
A few games also match you with strangers: Pulsar League's Play Online, Contrail Cup's public races, Packfall's battles and Slap Arena's Play Online. You see the other players' names and play against or alongside them, and that is all. Nobody can message you, and nothing about you is shared beyond the name you chose.
How online play is kept friendly
- There is no text chat anywhere on the site. Games that let players talk use preset phrases instead: "Good shot!", "Good save!" and "Good game!" in Pulsar League, quick phrases and map pings in Camp Kindling, emotes in Chaos Island and Contrail Cup. There is nothing to type, so there is nothing unkind to read.
- Player names are filtered. Every name you can choose is checked against a list of offensive words, including attempts to disguise them with numbers, symbols or look-alike letters, and names that try to share a social media handle, a website or a phone number are refused. A name that fails simply becomes a neutral one such as "Player 2".
- The server keeps the score. In games such as billiards, bowling, golf and the card tables, the score is kept by our server rather than by either player's browser, so nobody has to trust anybody else's arithmetic.
- Nothing personal is needed. No email address, no account and no real name. Pick any name you like for the room, and never put anything in it that identifies you.
If you ever see a name in a game that you think should have been stopped, please tell us through the contact page with the game and the name, and we will add it to the filter.
If a connection drops
Online games depend on everyone's connection. In the games that run through the site's own rooms, a seat is held for 45 seconds for anyone who drops out, so a quick reload usually gets you back in; several games also let you rejoin with the same code while the room is still open. Players a long way from our server, which is in Australia, may notice a short delay in the fastest games, such as air hockey; turn-based games such as billiards and the card tables are not affected.
