Stage 5 level 4

Impossible to complete. Probably a screw up by the game creator

Hope this is the level you mean. I finally figured it out.

1. Set the first lemming as a stop so the others don't walk over the edge. Obviously.

2. Dig straight horizontally left through the earth.

3. When you come out the other side to the three thin layers of earth, dig straight down through the middle one causing your lemmings to drop down and walk up and down the left layer.

4. At the top dig straight through to the left.

5. At the next mound of earth dig straight left through that as well.

Here comes the tricky part.

6. Have one of your lemmings climb the huge vertical wall and come down the other side.

Now we need to get this lemming to turn around and dig a tunnel down to were the other ones are.

7.Use the "mining" ability on this lone lemming and start digging a shallow diagonal tunnel. To get it to stop and turn around before it reaches the other side, make it start building stairs. It will then turn around and start going back up the tunnel.

8. After it has reached the surface facing the tower, use the mining ability again and dig a diagonal tunnel to connect with the others. If the tunnel stops short use one of the other lemmings to connect the tunnels by digging horizontally . If it's to high to reach you need to build stairs to connect.

9. Finally, build stairs to lead your lemmings over the leftmost tunnel(step 7) and you are done.

Good luck!

Use one blocker at the start, use a bunch of bashers to get to the steep cliff on the left. Assign a climber to go over. Then the tricky part: use the drill and halfway through change the lemming into a builder. After one or two steps it will turn around. Use the drill to get to the group, a basher if you end too far left. On the way up the drilled passage build stairs at the end. 3 stars easily if you time it right.
