Strategy guide
- 1.Focus on the stone - it's the only interactive element that can be moved;
- 2.Drag the stone completely off the PC to reveal the hidden area underneath;
- 3.Ignore text inputs and passwords; the solution is physical object manipulation.
Common mistakes
- 1.Trying to type a password on the keyboard instead of moving the stone;
- 2.Tapping the screen randomly hoping something will unlock the PC;
- 3.Looking for hidden buttons or codes instead of interacting with the stone.
