Net Game
Simple
RU English

This mission is an adaptation of the "Net" game (from Simon Tatham's Portable Puzzle Collection ). If you are lost or just want to play, the game is available here .

You have a rectangular grid with tiles you can only rotate, but it's a bit messy: tiles aren’t connected like they are supposed to be. You’ll have to put them in order by rotating each tile to reassemble the network .

The successful solution will be an entirely connected network with no closed loops.

There are four types of tiles:

• 90° turns
• T junctions

Tiles will be schematized by the directions to which they point ( N orth, W est, S outh, E ast), and more precisely with a string of directions (for example 'NE' if the tile is pointing to the Northeast, then it's a 90° turn).

Note that the order of directions in the string is meaningless (for example: 'NSE' and 'ENS' are the same) for input and output.

```

[['NW' , 'S'  , 'N'  , 'E'  , 'SE'],       [['SE' , 'W'  , 'S'  , 'E'  , 'SW'],
['NS' , 'W'  , 'NWE', 'NWE', 'SE'],        ['NS' , 'S'  , 'NSE', 'WSE', 'NW'],
['WSE', 'NSE', 'NWE', 'W'  , 'E' ],  ===\  ['NSE', 'NWE', 'NWS', 'N'  , 'S' ],
['WE' , 'WS' , 'WSE', 'SE' , 'WE'],  ===/  ['NS' , 'SE' , 'NWE', 'SW' , 'NS'],
['W'  , 'NE' , 'N'  , 'NW' , 'WS']]        ['N'  , 'NE' , 'W'  , 'NE' , 'NW']]
```

Input: A list of lists of strings.

Output: A list/tuple of lists/tuples of strings.

Preconditions:

• Given puzzles are solvable.
• 3 ≤ len(grid) ≤ 25, 3 ≤ len(grid[0]) ≤ 40.
• all(len(row) == len(grid[0]) for row in grid).
You should be an authorized user in order to see the full description and start solving this mission.

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

`pip3 install checkio_client`

`checkio --domain=py config --key=`

Sync solutions into your local folder

`checkio sync`

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

`checkio serv -d`

Alternatevly, you can install Chrome extension or FF addon

`checkio install-plugin`
`checkio install-plugin --ff`
`checkio install-plugin --chromium`

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
