Here is another trick (triple-basher canceling) : In superlemmini , you can have three bashers cancel each other , in a way , that will leave the terrain in a "small staircase shape" , and will help you complete a level like onml Tame 9 , by using only four bashers!
How to setup it : Load tame 9 , use release rate 88 for the space between the first and the second lemming , and release rate 99 for the space between the second and the third lemming.
When the first lemming reach the left wall , assign it as a basher . When the second lemming arrive in the basher's tunnel , you will see it's positioning having it a little higher that the first lemming for a few frames . Assign it as a basher , but only at the fame when it's position is at the highest pixel. It will start bashing , but in higher height , compared to the first lemming. Then the third lemming will find itself in the same height as the second lemming. Assign it quickly as a basher.
If you do it correctly , the third and the second bashers , both will cancel each other , and then the first basher , will immidiately stop bashing too. As a result , you wil lhave a "small staircase shape" at that part of the terrain , and you can use a fourth basher to lead the other lemmings to the exit.
Because this is a more complex trick that the previous ones , I have mentioned here , instead of pictures , I will post here a link for a video , where I use this trick to complete tame 9 with four bashers.
Here is the link for the video :
