No tricks are required. This is the last level I built before joining the forum and I will post one more level built in early 2020 for this season Spoiler: Hint Half of this level is red herring Spoiler: Video solution
@sealpanda Spoiler B can't step on zapper bots, but Z can! So stack 3 Zs so that the top Z can reach the goal
Interesting level, I liked it. But I didn't use fourth RZ bot. To win, 3 RZ bots are absolutely enough. Although it is possible to free all four, there is no point in this. Thank you
