So you're right ;-) Regarding the other warnings:\r\n\r\nThey should all occur in lib/ConnectFour/listhelp.ex. This module contains functions to manipulate and check a (ConnectFour) game field. To determine if a player has won we count the number of pieces of the same color. However we can only do this in vertical direction. In order to check for horizontal or diagonal wins, we rotate the game field. \r\n\r\nWhen only rotating 45° (diagonal win) a number of columns become superfluous: those less than four fields wide. It can be easily fixed by ignoring them (via wildcard) in the pattern in the `arrow_right/1` and `arrow_left/1` functions.\r\n\r\nI just noticed that the server does not start with elixir 1.1.1 because of problems in config.exs. I will fix that.\r\n\r\nSo, if you want to expand your PR, i will not merge it now, but wait for further commits :-)"}}
