Roeland I found that 15000 Teal tile image in https://wiki.diggysadventure.com/index.php?title=Tile_List is incorrect. This is how they look like
And there is a missing 630 cost tile in China
And could you add event tile in tile list ? There are specific 5, 7, 10, 13, 40 and 75 base cost tile in Egypt event. The tile cost x3 for challenge, x7 for Scandinavia, x20 for China, x40 for Atlantis, x70 for Greece, x100 for New World and x125 for Terra. The same tile in event will have same cost in same region. (Except in challenge, it will cost x3 of the same tile in normal)
For example, these tile (Atlantis/normal)
They are 10 (40x10=400), 13 (40x13=520) and 40 (40x40=1600) cost tile in Egypt event.
