How does it work

If at any point you experience some difficulty and require extra help, you can send these keywords.

HINT
Provides a hint to help you better understand your clue.

LOST
If you’re lost or can’t figure out where to go, the system provides a direction to the next point you should have reached by solving the puzzle.

BLOCKED
If the location from which you should obtain the clue is inaccessible (for example, due to roadworks), sending BLOCKED will automatically advance you to the next step.
