"The Secret Witness" is an atmospheric puzzle game in the style of a noir detective of the 40s. You are an investigator at a table with a green lamp, and in front of you are two words—suspects, suspected of conspiracy. Your task is to find the only witness, a clue word that connects both of them with an invisible associative thread. Each solved case is a flash of magnesium from an old camera and a pure "Aha! effect" when the brain instantly connects two distant concepts. Uncovered connections add to a personal dossier, and pocket watches count down precious seconds. Grow from Rookie to Major of Insight, collect error-free series for the score multiplier, and return for a unique "Day's Work." An error does not end the game — the witness is simply excluded, and the investigation continues. Hundreds of tasks, increasing difficulty, and an endless skill ceiling await you.
There are two suspected words at the top of the screen. There are witness cards at the bottom. Only one word is a common association for both suspects: it connects them. Find it and click on the card. Think about the meanings: which word comes to mind simultaneously for both the first and the second suspect. For example, "Sea" and "Sky" are connected by "Star". The pocket watch counts down the time — the faster you solve the case, the greater the bonus and the multiplier of the series. The "Evidence" button will remove one incorrect card (there are free daily ones, additional ones for viewing ads). The Skip button will open another case. The "i" icon on the suspect's portrait will show the meaning of the word. A mistake excludes a witness and costs one life, but you receive a small compensation and continue the investigation. Every solved case ends up in your file. Go through the "Business of the Day" and grow in rank!
