See a round before you play
An illustrative Classic round with five fictional players, one Mole and Similar Word. Words are shown together here only to explain the game.
1. Setup
Alex hosts; Bailey, Casey, Drew and Ellis join. Choose Classic, one Mole, Similar Word and Easy.
2. Private reveal
Alex, Bailey, Casey and Drew see Coffee. Ellis sees Tea. In play, each person sees only their own word, without a role label.
3. Spoken clues
In order: Morning, Roasted, Mug, Espresso, Leaves. Each player presses Submit Clue after speaking. Espresso may reveal too much.
4. Vote
Alex, Bailey and Casey vote for Ellis; Drew votes for Bailey; Ellis votes for Drew. Morning and Mug fit both drinks, so discuss the more specific clues.
5. Result
Ellis has three votes and is eliminated. Ellis is the Mole, so Operatives win. Eliminating an Operative instead would end Classic in a Mole win.

In Deep Cover, eliminating an Operative from these five players leaves four, so another round begins with the same Mole and new words. Eliminating another Operative leaves three and the Mole wins.

A complete party game in every browser
Undercover Word is a free social deduction game built for people sharing a room, a table, or a video call. One person creates a room, everyone joins from their own device, and the game privately assigns words and guides the group through clues and voting.
No download or account
Open the room link on a phone, tablet, or computer. Players only need a display name.
Best with 4–10 players
Rooms support 2–12 players. We recommend 4–10 for discussion, with players ages 13 and older.

A casual planning estimate, plus joining and explanation time. Deep Cover can span multiple votes.
