Clue is not a game of luck, it is a game of information. Every suggestion an opponent disproves, and every one they cannot, is a clue about the three cards hidden in the envelope. The trouble is keeping all of it straight in your head. This tracker records what you learn each turn, applies logic automatically, and narrows the field until only one suspect, one weapon, and one room remain.
Log each suggestion and what happened: which card you were shown, or which player could not disprove it. The solver marks cards as owned or cleared, applies backtracking logic across every clue at once, and shows the probability that each remaining card is the hidden answer.
There are three categories to solve: the suspect, the weapon, and the room. Any card you are shown is not in the envelope, so it is cleared immediately. When a player disproves a suggestion but shows the card to someone else, you still learn something: that player holds at least one of the three cards named. Track enough of those partial clues and you can deduce exactly who holds what. When a player fails to disprove a suggestion at all, none of those three cards is in their hand, which is often the most valuable clue of the game.
You suggest Scarlet, the Knife, and the Kitchen.
Does it handle partial clues? Yes, it tracks "holds one of these three" and resolves it as more is learned.
Can I undo a mistake? Yes, the tracker keeps a clue history you can step back through.
Does it work for different player counts? Yes, set the number of players and their hands.
Clue is solved by elimination. At the start of the game one suspect, one weapon, and one room are placed in the envelope and hidden; every other card is dealt to the players. Nobody can see the envelope, so the answer is whatever nobody holds. This tracker gives you a grid to record what you learn until only one card in each category remains possible.
Every suggestion you make, and every suggestion you watch another player make, is a source of information. When a player shows a card to disprove a suggestion, you learn that they hold one of those three cards, and when a player cannot disprove one, you learn they hold none of them. Recording who could not answer is often more valuable than seeing a card yourself, and the tracker keeps that history so you do not have to hold it in your head.
Each cell toggles between unknown, has it, and does not have it. As you mark confirmed holdings, the possible-solutions view narrows automatically toward the cards in the envelope. Make your final accusation only when the grid leaves exactly one suspect, one weapon, and one room unaccounted for, because in the standard rules a wrong accusation knocks you out of the game.
