Challenge 45 is actually not as difficult as you think. As long as all the boxes are successfully knocked out in the first eight levels (very simple), you can clear the customs.
(1) Build an arrow tower on the left side of radish and raise it to level 2. Then click on the box in the lower left corner. When the monster is coming, hit the monster. After a few times, you can raise the money to level 3. So keep typing the box in the lower left corner.
(2) Before the second wave, you can knock out the box in the lower left corner. The bomb in the first box was sold to the one on the upper right. Instead, it is poop. Other missiles are upgraded, and then poop is put in the position in the picture. This picture only needs to put the poop in these three places. In this way, the box marked in the figure can be continued.
(3) Soon the fishbone will be played out and upgraded to full level. In this process, it is very likely that the plane above the fishbone and the pylon below will be knocked out. Tell you what, sell the one under the plane and replace it with a pylon. Sell the two pylons under the pylons and replace them with airplanes. Then continue to hit other boxes.
(4) All boxes will be knocked off soon.
(5) Before the eighth wave, all boxes were emptied. Sell the sun and octopus according to the lineup shown below. Put an arrow tower in the open space around the track. Put the plane at the corner of the track. Put the rest on the plane.
(6) You will find that the 9- 15 wave is very simple. After 15 wave, the lineup shown below can be formed. After that, you can have a rest. However, you should note that there are sometimes one or two fish that slip through the net in these two dials. Use pause button more often.
(7) In fact, the golden radish is as simple as that.
