Field Op #84

Hi, Shilo243 here. For this week's Field Op, you are asked to secure the docks:

After accepting your field op at the HQ, go to the dock and stand near the trees in the right corner, near the entrance to the town:

Answer/click your phone when it rings and play the mini-game:

 

HOW TO PLAY:

There is one simple and good way to play this game and that is:

1. In the first vertical row, put the first symbol in ALL of the circles in that row and click scan.

2. Fill in the circle spaces that were green in the 1st row of circle into the second row of circles:

3. Fill the rest of the circle with the second symbol. 

4. Keep doing this method until it is correct. You will always have enough spaces with this option because there are only 4 choices so all you need is 4 rows :) 

If this was still confusing, fill free to look my work below:

This was my correct code! :D
