This is such a clever twist on parenting turning restriction into an opportunity for learning. You’re essentially gamifying access to gaming itself! A great starting point might be using a Raspberry Pi or Arduino with a solenoid lock and a small safe or lockbox. You can then program logic puzzles, math challenges, or even small coding problems in Python or Bash to trigger the unlock mechanism. It’s hands-on, educational, and way more engaging than passive screen time limits. Plus, it rewards persistence and creativity huge win.
