Steam confirms online co-op for up to six players; Steam joining and a developer-pinned room-code fallback are kept separate from exact current menu claims.
Pizza House Simulator supports single-player and online co-op for up to six players on Windows Steam. Steam does not list local split-screen, and no cross-play platform exists in the current official release. The developer documented Steam invites during the demo and continues to publish multiplayer fixes, but the sources checked do not show the exact release-build host and join menus.
Co-op facts checked for the release build

| Maximum group | Up to 6 online players |
| Solo required? | No; single-player is separately supported |
| Current platform | Windows through Steam |
| Local split-screen | Not listed |

| Latest detailed release notes checked | Patch v1.009 |

The player count and online mode come from the released game’s store page. Invite changes and earlier connection fixes appear in the official demo update archive, so they are useful troubleshooting history—not proof that every old demo problem still affects the paid game.
What is confirmed about joining
The developer's demo update history confirms direct Steam invites. Separately, a developer-pinned community checklist recommends a six-digit room code when Steam joining fails. The checklist predates the full release and does not prove that every current menu label or old demo bug still applies to the paid game.
Because no checked developer-authored source shows the complete release-build host flow, follow the multiplayer entry shown in the installed build. Try its Steam join path first; if the current room exposes a six-digit code, the pinned community checklist places code entry under Multiplayer → Join a Game. Treat that as a fallback, not proof that Steam invites are unsupported.
If a room is visible but joining fails
The developer previously documented a “session found but cannot join” correction and a room-code fix in the demo. For the current release, use only checks that follow from those known variables:
- close and relaunch the game on host and guest;
- verify neither player is on a beta branch or an older public build;
- create a fresh room instead of reusing the stale lobby;
- try the current Steam join or invite path once;
- if that fails and the current build exposes a six-digit room code, try it once through Multiplayer → Join a Game;
- swap hosts to separate a host-side problem from a guest-side problem;
- check the official update archive for a current outage, hotfix, or changed join flow.
Do not disable security software, open broad router ports, or download an unofficial patch as a first response. The official sources do not require those changes.
Current multiplayer fixes through Patch v1.009
Patch v1.007 fixed simultaneous repair counting, fake guest fryer baskets, and delivery-tray visibility. V1.008 fixed guest pizza continuing to cook after removal from the oven. V1.009 re-synchronized guest-rolled dough, held items, item effects, and sounds. These are specific release fixes, not evidence that every connection problem has been resolved or shares one cause.
Demo fixes versus current co-op behavior
The June demo notes also mention a portable order tablet, solo pause behavior, disappearing dough, stuck held items, save/load money, and counter-collision fixes. They establish what the developer changed during testing. They do not establish that those bugs remain in the August 19 release.
For the game overview, price, official download, and solo-first plan, return to the Pizza House Simulator guide. If a player can connect but the game runs poorly, compare the PC against the official system requirements before treating frame rate as a network failure.
If the problem is specifically a lobby that appears but refuses the guest, use the shorter Pizza House Simulator co-op connection checklist. It isolates version, Steam join, room-code fallback, stale-room, and host variables without repeating the broader reference page.

QUICK ANSWERS
Questions players ask next
How many people can play Pizza House Simulator co-op?
Steam advertises online co-op for up to six players. Start with two players to prove the kitchen and connection flow before filling the lobby.
How do I invite friends to Pizza House Simulator?
Use the multiplayer option shown by the current build and try its Steam join or invite path. If that fails and the room exposes a six-digit code, a developer-pinned community checklist recommends entering it through Multiplayer → Join a Game.
What should I do if a friend cannot join?
Confirm all players use the same public build, recreate the room, try Steam joining once, use the room code fallback if available, then test a second host. Record the exact error, build, host, guest, and failure point.
Does Pizza House Simulator have local split-screen co-op?
The current Steam listing advertises online co-op but does not list shared-screen or split-screen play. Do not buy it for couch co-op unless the developer confirms that feature later.
Does Pizza House Simulator support cross-play?
No cross-play support is confirmed. Windows Steam is the only currently listed build, so there is no verified console or Mac platform to connect across.
