This post details the unusual finish of Nakamoto Extreme 83, with three more interdependent BARN’s, well assisted by Medusa coloring.

From the first cluster trap and BARN, further expansion and the aligned triple continue to move Nakamoto Extreme 83 towards the exit door.

In particular, the second aligned triple’s 4r8c1 removal brings a second BARN, and its expansion traps below

The follow up   

brings a third BARN, and that BARN’s removals set up

a fourth.

Then after a shortcut XY ANL (left) expands the cluster for three more traps

the next expansion wraps green in c6, for the immediate collapse of Nakamoto Extreme 83.

Next time, it’s Nakamoto Extreme 103.
