from Kancolle Wiki
So yea before there was boat wives the anime there was boat wives the game. If the quote from the wiki page didn't explain it well for you then Kancolle is a WW2 boat battle browser game where the ships are all girls and you fight the Abyssal Fleet who rule over the sea. There are different classes such as destroyers and light cruisers and all in all there are a total of 221 boats to get as i post this (new girls don't come out constantly i believe it's seasonally if any). Remember they are, in fact, based off actually WW2 ships.
Examples of said boat girls under spoiler (art from game).
If the anime has you wanting to play but you have no clue on how, this topic will be showing you how you too can be an admiral battling the unknown sea.
If anything is unclear/there are problem/issues post here and i will try to find a solution, or you can check the wiki on how to register here and possible find a solution to your problems
I'm saying this right now google chrome is the best when you want to play this as there is an app that will help u skip a step
Mobile playing is a no-go, sorry.
Also depending on your timezone this may or may not require some effort into actually getting to play
Step 1
Register for the website
Step 2
Get the app (for chrome users)/Get a Japanese VPN (for nonchrome users)
Step 3
Win (the lottery)
There's my instructions on how to play Kancolle for anyone interested, any questions leave them in the comments below so I can maybe answer and maybe tomorrow I'll post on getting started with the game since it's all in Japanese
Remember once you set sail and start playing the game, USE THE KANCOLLE WIKI OR ELSE YOU WON'T UNDERSTAND ANYTHING unless you can read Japanese.
