TRUTH FINDER: A Quest of Logic

As you progress, you will unlock new levels and logical challenges while earning up to 300 stars for completing levels quickly.

For more information, see the in-game tutorial or download the full game manual (in PDF).

TRUTH FINDER is currently available for desktop platforms only. Mobile devices are not supported.

❖ Gameplay

Two differently colored Stones fall down the game Board one after the other. Your goal is to complete all the required logically correct horizontal lines before the Stones pile up to the top.

To achieve this, you can move the Stones left or right and change their color as they fall. Completing all the correct horizontal lines wins the level. If the Stones reach the top of the Board, it is game over.

❖ Story

You are Alex Vanth, a researcher at the prestigious Cours Industries, Inc., a cutting-edge research corporation led by the enigmatic billionaire Frederique Cours. While investigating a tropical island on your latest assignment, you uncover a mysterious puzzle mechanism that operates on fundamental principles of logic. Can you solve all the puzzles and uncover the ultimate truth?

❖ About the game

TRUTH FINDER is a proof-of-concept game inspired by the truth table technique, a method developed in the late 19th and early 20th centuries for studying the foundations of mathematics and logic. Pioneered by philosophers such as Peirce, Wittgenstein, and Russell, this technique remains fundamental to modern logical reasoning.

At its core, the game is built on the syntax and semantics of classical propositional logic. The key mechanic is a truth table decision procedure, where your goal is to arrange truth values TRUE (represented by green Stones) and FALSE (represented by red Stones) to correctly evaluate logical sentences on the game Board.

❖ Features
