Tips for a live hunt

  • Tap GPS on the map to follow your real location as you walk, and allow location access when your browser asks. Location only works over a secure (https) connection.
  • Keep the screen awake and this tab in front. Phone browsers pause GPS and timers when the screen locks or you switch apps, so timed puzzles and moving zones can stall. Return to the tab and they pick back up.
  • Your progress autosaves on this device. You can close the tab and press Resume later to continue where you left off.
  • Solving from home or out of signal? Switch the map to Move mode and drag the marker by hand instead of using GPS.
  • Bring a charger and jot down the posted coordinates. A phone browser is not a rugged handheld, and continuous GPS drains the battery.

Frequently asked

Do I need to install an app?
No. It runs in any modern mobile or desktop browser, and nothing is uploaded. The cartridge runs entirely on your device.
Does it use my real GPS?
Yes, in GPS mode. Move mode lets you drag the marker instead, which is handy for armchair solving.
Will my progress survive a reload?
Yes. It autosaves to this browser and offers Resume. Saves stay on this device and browser, so they do not follow you to another phone.
Why did a timer or zone freeze while my screen was off?
Phone browsers suspend background tabs, which pauses timers and location. Keep the screen on during timed sections.
Does this log my find on Geocaching.com?
No. It is a standalone player. Enter the completion code it gives you wherever the cache asks for it.
A cartridge behaved strangely. What now?
Most cartridges work, but if one leans on an unusual feature you can open it in the Wherigo Solver to inspect it, or send a message with the cartridge name.
