[image] Sebb: defmodule War do import Enum @trace false def play(decks) do round_(:normal, decks, []) end defp round_(state, {deck_1, deck_2}, pot) do if @trace, do: dbg({state, {deck_1, deck_2}, pot}) round(state, {deck_1, deck_2}, pot) end defp round(_, {[], []}, …

Where are these tests from? I do not see anything about an “ace weight” in the requirements. What I did not consider is that the deck comes in already shuffled. Its not clear to me whats happening here: test "deal_4" do t4 = [10,11,12,13 ...] r4 = [1,1,13,12,9 ....] assert War.…

I tried to dig on these test cases but no success :confused:

how does your deal function look like now?

like that: defmodule War do @doc """ The main module to the challenge. This module exposes a deal/1 function to play the game. """ # prefers to use a weight as we don't # need to represent the card suite @ace_weight 14 def deal(deck) do {p1, p2} = deck |> Enum.map…
