So I have a question regarding the authenticity of the screenshot:
How can you generate a vault on the top row?
Coins & Bags fall from the top - with occasional wooden chests. Let's say you got 2 wooden chests to drop, and moved a third on from the second row to the top row, placing a green chest at the top-right corner. Then you could repeat that (with WILD luck) and perhaps get a red chest on the third-from-right position.
Then you would need to get some more lucky matches to shift that red chest to the right twice WITHOUT TOUCHING ANY OF THE LOWER ROWS.
Then you would need to repeat that twice more, to get a vault on the top row.
But the screenshot shows TWO vaults on the top row - and they are ADJACENT!
That's just too much for me. The thought of how many perfect drops you would need to make that happen is... just not really in the realm of skill.
