How It Works

01

Daily Quick-fire

A real diagnostic or design task. Sensor data, alarms, schematics. Solve it fast. 5–15 minutes. No account needed — but XP only counts if logged in.

02

Weekly System Challenge

Full engineering system design — PLC code, robot paths, optimization. Solo or up to 3 engineers. One week to submit. Peer-graded.

03

XP & Levels

Every correct answer earns XP. Level up from Technician to Lead Engineer. Streaks multiply XP. Your profile tracks all history.

04

Team Collab

Weekly challenges support real-time collaboration. Share an invite link — teammates see each other's cursors live and edit the same workspace together.
