Read the vehicle report carefully — year, make, engine, mileage, and the customer's description all matter.
Select your diagnosis from the dropdown and press FILE. You have 6 attempts to identify the correct fault.
After each wrong guess, a new diagnostic clue is revealed — live data, test results, or inspection findings.
The tile grid shows how close each guess was across 8 dimensions: System, Sub-system, Root Cause, Component, Severity, Pattern, Frequency, and Related Fault.
■ Green = exact match ■ Amber = close ■ Blue = same family ■ Red = wrong

Mechle is a daily car diagnostic puzzle game for mechanics, technicians, and automotive enthusiasts. Each day presents a real-world repair scenario — your job is to identify the root cause in as few guesses as possible.
Cases are based on common real-world diagnostic patterns encountered in professional repair shops. The symptoms are intentionally ambiguous — just like the real thing.
Built with love for the trade. New puzzle every day at midnight UTC.
