We have a little tip for you on how to solve The Puzzle in Lost Land.
Click on the stone to see 4 glyphs. Select the needed glyph. It should match the glyph you'll see on the rock above each of the stones.

 

As for the mobile version, there is a second page when choosing the glyphs. The needed glyph can be right there.

 

This is the clue that will help you complete this puzzle!
We believe in you!
