# New contest type proposal: cross-codes [duplicate]

Cross-codes is making a crossword puzzle, but with codes.

For example, We have a 10*10 (not constant, this means the size may vary for each contest) grid:

..........
..........
..........
..........
..........
..........
..........
..........
..........
..........


And your code is MY_CODE, you can place your code anywhere in the grid, vertically or horizontally.

For example:

..........
...MY_CODE
..........
..........
..........
..........
..........
..........
..........
..........


Next, Let's assume the next code is MOM.

The poster could place it like

..........
...MY_CODE
...O......
...M......
..........
..........
..........
..........
..........
..........


But not like:

..........
..MMY_CODE
..O.......
..M.......
..........
..........
..........
..........
..........
..........


Because it is adjacent to another code which is MY_CODE, making it look like MMY_CODE.

The winner would be the one with the most codes placed, when there is nobody able to place a new code on the grid for a set time period (ex.1 week).

• @PeterTaylor I do not see why it is a dupe. – Matthew Roh Apr 14 '17 at 9:06
• It's not the same question, but it should be an answer to that question. – Peter Taylor Apr 14 '17 at 9:16
• @PeterTaylor I felt this criteria specifically needed so I made a criteria proposal – Matthew Roh Apr 14 '17 at 9:18
• Hasn't it been done already? – plannapus Apr 14 '17 at 10:37
• Yeah, this isn't a challenge type, it's just a single challenge, which should be posted in the sandbox. It's also already been done. – mbomb007 Apr 14 '17 at 13:31
