Description (written by the developer; not a statement by this register)
Devil Marker (or デビルマーカー) is a niche Japanese board game which is very simple yet complex at the same time! Play IRL from 1 device or in game with other people and develop new strategies! Take a look over the in-game tutorial to understand the rules and customize your experience by buying custom skins, creating custom music playlists and changing the interface colors. You get in game cash passively by playing! So, with that, go give it a try and I hope you have fun! If you find any bugs, make sure to report them! Thanks! :D
