I know. Just do this:

• Run mix setup to install and setup dependencies
• Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000/new from your browser.

The default grid size is 6 but you can change it on the URL like localhost:4000/new?size=5. Should work with other values but the layout might not cope :) Not sure what the bug is to be honest, it looks random.

Anyway, you can always go to game_live.html.heex and make sure grid-cols-6 becomes grid-cols-4 if looking to play on a 4x4 board.

No worries. You can run some tests and build some dopamine with mix test. The coverage ain't high but it covers the most important part of the game: sliding tiles.

I got you covered! Just launch another window and go to the same URL. Now you can all play!

But how does that work? you ask. Good question. I'm not sure. I guess all players need to cooperate until near the end... by the time there's a tile > 1024 every player should start thinking about winning on their turn. Does that make any sense? I'm not sure either.

I can see clearly now, the rain is gone

I can see all obstacles in my way

I digress. That's something I did to make things harder. I'm placing 3 obstacles randomly on the board placed to make everything harder. Not sure how much harder though. Good luck man. It should still be possible to win...

...I think.
