Hi all. If you haven't checked your free ink options in the app lately, you should. Right now there's an option to install and play "Pirates of the Caribbean: Tides of War". Reach level 7 with your captain character and you will get a sweet pile of 7,500 ink.
Typically it takes about 3 hours of play to get that far, however, today there is a in-game special event going on where you can level up buildings with no wait time. We did a level 1 to 7 speed run in about 45 minutes (not counting app download time which was about 15 minutes). Focus on doing the quests that the first mate offers in the lower left corner and you should rapidly rise in level.
Oh, don't confuse captain level 7 with castle/fortress level 7. You want your character in the upper left corner to reach level 7 to get your 7,500 ink.
