Turing Machine Game is a digital adaptation of the famous deduction board game Turing Machine, paying tribute to Alan Turing, the pioneer of computer science and cryptography.
This version, designed at UTBM, reimagines the game in a student context — where players solve algorithmic puzzles to gain access to an exam room.

Project concept

Players receive a challenge email from a professor containing a logical riddle.
To enter the exam room, each student must find the correct password by proposing combinations that are tested against the rules of the riddle.

Each password:

• Is unique, generated based on the student’s INE (student ID)
• Must satisfy a set of logical conditions
• Becomes invalid after each use to prevent cheating

Before starting, players choose a difficulty level, which affects both the complexity of the riddle and the score multiplier (from ×1.0 to ×1.8).

A multiplayer mode is also available, where students compete to find the solution first — in this case, no INE is required.

Game features

• Difficulty selection impacting logic depth and scoring
• Validation system for each proposed password
• Multiplayer mode with real-time competition

Core logic

To compute a unique solution, we designed a recursive functional filtering system that progressively narrows down possibilities.

Ω = { (x₁, x₂, x₃) | xᵢ ∈ {1, 2, 3, 4, 5} for i = 1, 2, 3 }

Each filtering function (noted f₁, f₂, f₃, …) reduces this set step by step:

Ωₖ = fₖ(Ωₖ₋₁)

The process continues until there is only one combination left (|Ωₖ| = 1). If, after six filtering steps, more than one combination remains, the algorithm backtracks and tries a new sequence of filtering functions.

This guarantees that each puzzle produces a single valid solution, determined through a logical and deterministic process.

Turing Machine Game combines logic, mathematics, and software engineering to deliver a faithful yet original digital experience — both a technical and creative tribute to Alan Turing’s legacy.
