Revision as of 16:43, 1 May 2021 by Dvgrn(talk | contribs)(It doesn't just "resemble" half a blockade -- let's just add a little more specific detail instead)
The blockade is a common formation of four blocks and is one of the familiar fours. A common evolutionary sequence that leads to its formation is known as lumps of muck, which can be seen by letting the stairstep hexomino evolve.
A half-blockade is an 8-bit constellation consisting of two blocks with two empty rows separating them, offset by one cell.
