**ADDITIONAL TOOL FOR STRICTER CHECKS:**

Check out this tool by notgreat from the Discord for stricter checks, including molecules moving in multiple directions and basic in-between cycle collisions.

**UPDATES TO THE PUZZLE:**

- There is no longer an instructions secondary, so you can now loop your 6T solves. (pls)

- For stricter verification purposes, all solves will also be stricly checked against and have to pass the 6 test cases below in game manually to be valid, if your solution does not pass any one out of these you will be notified.

Cost / 5 + Cycles + Area

Bonus 10 points for solving

Metrics are of the worst test case out of the 64 possible inputs.

Area is based off of the on-site simulator, which may differ from the game on large swings.

Data Packet Input

Data Packet Output

Elemental Salt x2

Elemental Fire x2

Elemental Gold

As with tradition, the last puzzle of the tournament is a computation puzzle. Where one must solve a puzzle that requires you to conditionally solve several different test cases with one solution.

The goal of this years puzzle is to implement the elementary cellular automaton Rule 110 within the game. Where fire (△) represents 1 and salt (Ө) represents 0. The input and output wheels are to be read counter-clockwise.

If you aren't familiar with elementary cellular automata, heres a simple rundown. The state of each cell in the output is determined by the corresponding cell in the input and its neighbors. Each configuration of 3 cells has its own corresponding output. The ones for Rule 110 are as follows:

Input | △△△ | △△Ө | △Ө△ | △ӨӨ | Ө△△ | Ө△Ө | ӨӨ△ | ӨӨӨ |

Output | Ө | △ | △ | Ө | △ | △ | △ | Ө |

You can find more info on elementary cellular automata on the wikipedia page.

And if you don't know where to start, you can check out this page on a few properties of Rule 110.

There are a certain few additional rules that come with this puzzle for a solution to be counted as valid as well. Keep in mind that not all of these rules will be verified by the site!

1. Your solution must be able to solve for all 64 possible inputs.

2. Your solution must still work if the conditional reagent changes after each pull, and the conditional product changes into the next corresponding output after each drop.

3. Your solution cannot drop an invalid product of the same shape over the output.
