Undercover Game Words List: 24 Pairs and How to Choose Them
Use these 24 word pairs to host an offline round or design your own deck. They are editorial suggestions, not the answers to a current CoolJev game. Each pair shares a setting but leaves a difference that a clue can reveal. The groups below describe topics, not measured difficulty ratings.

How to use the list with six players
Pick one row and secretly give word A to five players and word B to one. Each player describes their word without naming it, then the group votes. Swap A and B in another round so the second column does not always identify the undercover. Agree on ties, elimination and victory before dealing; different party versions use different rules.
In CoolJev elimination mode, a tied vote removes nobody, eliminating a civilian starts another round, and catching the undercover wins for the civilians. The undercover wins at one-to-one parity. In three-round mode, the final vote must catch the undercover; a tie or a wrong target wins for the undercover. See the AI game rules for early accusations.
Choosing a clue without naming the word
For Desk lamp / Flashlight, “It makes light” fits both and reveals little. “During a power cut, I carry it into another room” adds mobility and a setting. It is a teaching example, not a winning script: earlier clues change what the sentence adds.
Choose words everybody knows. Start with a shared setting, then identify a contrast someone could describe. Unrelated words can expose the odd player immediately; regional synonyms may offer no real difference. Replace disputed pairs rather than treating unfamiliar vocabulary as deception.
What changes when you play with AI?
CoolJev seats one human with five AI players. Gameplay is currently in Chinese. This English list is for your own games: it cannot be imported, and the online game uses its own word library. It does not offer an English game mode or a blank-word Mr White role.
Each AI receives its own word and all public clues available at its turn. Jev compares bounded identity hypotheses and prepared speech or voting options. Code handles dealing, legal actions and victory. After the game, inspect the recorded evidence, options and scores instead of assuming the model inferred a role correctly.
Read the AI Undercover case or play in Chinese. For the implementation distinction, see Jev versus if/else and the TypeSafe documentation.
