If the origin of the grid was at the top-left and the "X" was at position (2,1), shouldn't placement also be allowed at (1,1), (4,1), (0,2), (4,2), (0,3), and (0,4) as well? Each of these placements would match and keep the size within a 4x4 grid.
Hi,
just to be sure, that everything is clear:
- the stack on the left side is just for being able to plan your moves
- the single tile right of the stack is the one you can try to put on the table
- for doing that it must be located beside a tile already placed on the table (except move #1

) following these rules...
1) NORMAL MOVE
the tile must be used as it is seen (without rotating or fliping the tile) - if possible
2) FORCED MOVE
if there is an empty space which has two neighbors with the same color ending there, this space MUST be filled immediately (that's what is seen on your screen shot)
3) NO MOVE ALLOWED? DO WHAT YOU WANT
if nothing else is possible, you can flip or rotate the tile as you like (then all possible orientations are seen instead of a single one)
Hope that helps!
If anyone is able to write the rules in a way that they will be understood easier - please do it!
