Editing Air Castle

Air castle is a 6 tile formation used for 2442 endgames* and is the most optimal formation for the final 1024 before the 65536 tile**. It looks like this:

2      2    4   8

512 256 16 32

X     X    64 X

X     X   128 X

The most common ways to set this up are via 2244 (commonly known as LL) and 2442. The latter is much more difficult to set up initially, but once it is set up, air castle is easier to play than it is in LL.


Theory:

If there is a 4 above the 2 in the gap (assuming the orientation is the same as the above graphic), that is often actually completely fine, and the table will often be fine with that situation, especially if you only have to make a 32 or 64.
