A. Solve the Left Green Ear.

The left ear can be at any of the 4 squares on the top row, so we have 4 cases to work from.

Setup: Make sure that the blank tile is at the front-left (by doing an F+3 move).

Case #1:

The left ear is already located at the leftmost top tile, so you can continue onto part C: Solve the Right Green Ear.

Case #2:

The left ear is at the 2nd tile of the top row.

Do the move:

Do the move:

Do the move:

F-2 R- F-1 R+T+2 L+ T+1 L-

Result: the left ear is now where it is suppose to be.

Case #3:

The left ear is at the 3rd tile of the top row.

Do the move:

Do the move:

Do the move:

F-2 R- F-1 R+T+2 L+ T+1 L-

Result: the left ear is now where it is suppose to be.

Case #4:

The left ear is at the rightmost tile of the top row.

Do the move:

Do the move:

Do the move:

F-2 R- F-1 R+T+2 L+ T+1 L- F-2 R- F-1 R+T+2 L+ T+1 L-

Result: the left ear is now where it is suppose to be.

B. Solve the Right Green Ear.

The left ear is at the leftmost tile of the top side.
Now we have to get the right ear at the rightmost tile of the top side.

Setup: Make sure that the blank tile is at the front-right (by doing an F-3 move).

Do the move:

Repeat the move:
(2 times max.)

Do the move:

F+2 L- F+1 L+T-2 R+ T-1 R-

... until you have double green links on the top row

Result: All of the green links are solved.
In fact, the entire puzzle is solved.

You are probably wondering; why solve the red links adjacent to the yellow links? And why solve the green links last?. The answer is: you can build up the Missing Link puzzle at any color combination you want. However, it is important that you build the first two sides of any color (that use 4 tiles total each) adjacent to each other. It is then important that you build the WHITE row (with only 3 tiles) immediately afterwards. The other 4 tiles are solved last, regardless of the final color of that row.
