Day 93 of 101 DoCC – this is my fourth play with cellular automata – hereSnipe! The codepen challenge this week was birds, so I couldn’t resist. This one is using a grid and the first set of rules is from John Conway’s Game of Life.

Click to rerun and use the spacebar or arrows to change the rules. Here is a full page version. This works best on a computer.

See the Pen snipe by Sophia (@fractalkitty) on CodePen.

### Rules:

- Set 1:
- If a cell is alive and has less than 2 or more than 3 alive neighbors, it dies.
- If a cell is dead and has 3 neighbors alive, it comes back to life.

- Set 2:
- If a cell is alive and has less than 2 or more than 5 alive neighbors, it dies.
- If a cell is dead and has 3, 4, or 5 neighbors alive, it comes back to life.

- Set 3:
- If a cell is alive and has greater than 5 alive neighbors, it dies.

- If a cell is dead and has 2 neighbors alive, it comes back to life.

- Set 4:
- If a cell is alive and has less than three alive neighbors, it dies.
- If a cell is dead and has 1 or 2 neighbors alive, it comes back to life.

- Set 5:
- If a cell is alive and has 0, 1, 7, or 8 alive neighbors, it dies.
- If a cell is dead and has 0,1, or 2 neighbors alive, it comes back to life.

- Set 6:
- If a cell is alive and has 0, 1, 6, 7, or 8 alive neighbors, it dies.

- If a cell is dead and has 0, 1, or 2 neighbors alive, it comes back to life.

- Set 7:
- If a cell is alive and has an even number of alive neighbors, it dies.
- If a cell is dead and has 0 neighbors alive, it comes back to life.

- Set 8:
- If a cell is alive and has 0, 1, 5, or 8 alive neighbors, it dies.
- If a cell is dead and has less than 3 neighbor alive, it comes back to life.

- Set 9:
- If a cell is alive and has 0 or 8 alive neighbors, it dies.
- If a cell is dead and has 0 neighbors alive, it comes back to life.

- Set 10:
- If a cell is alive and has 3 alive neighbors, it dies.

- If a cell is dead and has 0 neighbors alive, it comes back to life.

- Set 11:
- snipe

- Set 12:
