The Freak Circus endings guide
The short version: there is one ending right now. The official itch.io page lists "1 Bad ending" under current features, names four more as planned, and states outright that the script is a work in progress and no endings are fully planned yet.

About the "8 endings" claim
You will see other sites claim eight or more endings, with names like True Ending and Secret Ending. Those counts usually come from treating the point where the build stops as an ending, or from nothing at all. We list only what the developer has said, and label the status of each.

Missing — Day 1 bad ending
In gameReachable now
How you get it
Choose "do nothing" when Pierrot is being ridiculed by a man in the street on Day 1, and keep the pink ticket.
What happens
You go to work, receive a pink ticket from an unknown man with no option to refuse, and head to the circus after your shift. The Ticket Taker punches your ticket and escorts you straight to the pink tent, where it is dark and you are knocked out. You wake unable to move your arms or legs or speak. Each member of the circus rejects you in turn, until the Ticket Taker suggests devouring you instead. The screen goes black: "You failed to catch Pierrot's attention... and met a tragic end."

Two Day 3 bad endings
Creator confirmedIn development
How you get it
Part of Day 3, which is unreleased.
What happens
The developer has referred to two further bad endings tied to Day 3. Their names have not been announced, so the placeholder titles you may see elsewhere are not official.
Things that are not endings
"The Day 2 open ending"
Creator confirmedNot an ending
How you get it
Simply finishing Day 2.
What happens
Several sites count the point where the current build stops as one or more "open endings", which inflates the total to numbers like eight. It is not an ending. The itch.io page counts one bad ending, and states that the story continues for one more in-game day still in development. If you reached the end of Day 2 you did not miss anything.

How this site labels information
We do not invent endings, stats or plot. Anything that cannot be traced back to the game itself or to something the developer said is labelled as a theory or as unconfirmed. Editorial policy
