For the life of me must have been thru walkthru 5 times and still have 13 tiles I cannot find...been thru the tunnels numerous times and still to no avail...any secret walls or doors I might have missed?
pixel_player23812106 Yes, there is a secret bonus room that opens when you put the four boulders in the tunnels on the gold spots.
In the future, when you are stuck you can check the maps in the wiki:
Click on the map sign next to the corresponding mine.
In these types of scenarios it is much more easier to consult, study & follow the maps instead of the videos.
Have you checked out the relevant Wiki pages, quests, maps, videos, guides, walkthroughs & hidden gifts.
You can easily find the solutions to puzzles if you check out the walkthroughs & maps.....everything is clearly & concisely highlighted.... including hidden gifts.
The Wiki pages & this forum will become your best friends throughout your Diggys Adventure journey.
