Eater Welding Guide

[confocaloid]

A related puzzle is finding a variant (of one eater or a constellation of eaters) fitting in a situation where the usual choice doesn't fit. Here are possibilities for two eaters oriented in the same direction:

Drifty eater 3 + eater 2 + eater 1 (normal drifty eater 3 can also function as eater 1)

It can eat a glider in another way, but for most purposes that probably doesn't make it less useless:

Drifty eater ...

... can eat a glider in another way ...

BTW, that additional glider is eaten by a welded known object acting as a glider eater, not in the Hickerson's stamp collection.

Code: Select all

x = 9, y = 14, rule = LifeHistory
