Inner ring

8 positions

Survival counts

B{3} / S{2,4,5,6,7,8}

The eight immediately adjacent cells. Empty rows disable that ring’s birth or survival pathway.

Outer ring

Birth counts

Survival counts

B{0,1,2,3,5,7,8} / S{1,2,3,4,5,6,7,8,11,16}

Only the sixteen cells just outside the inner ring; center and inner cells are excluded. Empty rows disable that ring’s birth or survival pathway.

Resolution

Update mode

Both rings read the same frozen board. Agreement stands; on disagreement the chosen ring can allow or deny life.

Birth conflict winner

Survival conflict winner

Birth priority applies to currently dead cells; survival priority to currently living cells. In sequential mode only the active ring decides.

Rule edits pause and preserve the field. Changing mode restarts the sequence at inner. Other edits preserve its phase. Reset restarts the opening.

Two Rings

Eight near neighbors and sixteen further neighbors follow independent rules. Let them decide together with separate birth and survival priorities, or alternate one ring per Step.

Current composition

01Inner ring counts 8 immediate neighbors. Outer ring counts 16 further neighbors, excluding the center and inner ring.
02Each ring uses its birth mask for a dead cell and its survival mask for a living cell.
03Both read the same board. inner wins birth conflicts; inner wins survival conflicts.
