HOW TO PLAY

  1. Press Start Shift to begin a 45-second inspection run.
  2. Read the active rules: allowed color, maximum pins, and the hidden defect that must be rejected.
  3. Tap the module to inspect its back scan, then choose Approve or Reject.
  4. Rules rotate every 4 modules. Wrong calls cost 5 seconds, so speed only matters if your checks stay accurate.

ABOUT

Faultline Check is a short inspection game about reading rules and verifying evidence under pressure. Instead of simply sorting by color, you must compare every module against changing constraints and sometimes flip it to reveal a hidden defect. Your best cleared-module count is saved on your device, and the sharpest inspectors reach the global TOP 20 leaderboard.
