For this match, there are 2 options that i want you to choose from:
1) have a table which will be filled in with the attempts and solutions;
The advantage of this that it's easy to follow, though the con is that it takes a long time to edit and it usually needs waiting.
2) only have a comment-based system;
This solution does not use a table. You simply make your guesses and your opponents react to it, while you write it down somewhere on a comfortable space.
Also, since this is Sandbox, you only need to send your codes to me if you're going to use a table and have me edit it (you can copy-paste and edit sample tables too
), but otherwise it's enough if you yourself know your own code.
