Invite Steam friends through the in-game phone
Getting your classmates together starts with the game's phone, not a guessed lobby shortcut. For Worst Class Ever how to play with friends, the documented demo answer is to use the Steam-friend invitation feature in the in-game phone. The developers added that route in Demo 0.1.6 on October 16, 2026, giving friends a specific invitation entry point.
If you are using a build with that feature, look for the Steam-friend invitation function in its phone interface. The announcement identifies where invitations come from, but does not publish a button-by-button sequence or a separate room-code method. Use the labels shown by your build rather than assuming another game's lobby controls apply.
There is an important timing distinction for anyone planning a session now. The developers announced that the demo would be taken down on November 3. As of this November 5 guide, the invitation route above is a documented demo feature, not a claim that a new player can still download the demo or that the full release uses an identical interface.
Check whether your group is planning for six or eight players
The official Worst Class Ever Steam page describes the original format as one teacher facing five students. Students blend among NPC classmates while the teacher tries to identify them.
The October 27 full-release announcement instead promises support for up to eight players per match. That is an announced increase, not evidence that an older six-player demo lobby can be expanded to eight.
| Version context | Supported group-size information |
|---|---|
| Original demo format | One teacher and five human-controlled students |
| Announced full release | Up to eight participants per match |
| Announced custom rooms | Adjustable player count and number of teachers |
Do not assume that an eight-person session always means one teacher and seven students. The developers separately announced configurable teacher numbers, without publishing the full set of allowed combinations.
Room joining can depend on the round ending
Demo 0.1.7 changed room logic so new players could join after each round ended. If a friend is already playing a round, that documented joining window matters when arranging the next session.
The demo updates also discuss a Room List and public-room joining. They establish that rooms are part of the multiplayer flow; they do not establish every privacy option, password field or invitation-acceptance screen. Avoid treating an imagined private-room setup as a required step.
For a group using the documented demo system, coordinate around a round boundary and the phone's invitation feature. That is more useful than repeatedly assuming a friend must be able to enter the current round immediately.
Agree on the match before class begins
Students and teachers have different jobs. Students need to misbehave without standing out among NPC classmates, while the teacher watches for signs of real players and catches offenders. Discuss which side each friend wants to try so everyone understands the basic matchup.
The full-release announcement adds custom rooms with up to 20 configurable settings, including player count, teacher count and item-spawn rates. LAN support is also announced. Those plans give a group more to consider, but do not provide a verified LAN setup procedure or a custom-room creation tutorial.
Check the current Steam listing when scheduling a launch session. The developer announcement gives November 10, 2026, while the captured store listing displays November 9. Use the store's availability information rather than treating either date as a universal unlock hour.
FAQ
Where is the documented friend-invite feature?
Demo 0.1.6 added Steam-friend invitations through the in-game phone. The update does not supply exact button labels or a complete acceptance sequence.
Can eight friends play the demo together?
The documented original format supports six participants. Eight-player matches are an announced full-release change, not a verified demo option.
Can a friend join while another round is running?
Demo 0.1.7 explicitly allowed new players to join after a round ends. The source does not establish unrestricted mid-round entry.
Is LAN the same setup as a Steam invitation?
The available material does not establish that. LAN support is announced for the full release, while the phone invitation feature is documented in a dated demo update.
