Please stop calling DnD a 'board game'. Your lack of knowledge on the topic is showing.
Technically, it IS a board game. But not in the classic sense of it coming in a box with a game board like Monopoly. A lot of DM's use home made maps to place your mini character. Also, using LED flatscreen "game tables" are very popular right now as well to lay out dungeon maps, town maps etc to work with your character miniature. You roll dice (though not to move, but to see success/failure of actions).
But most D&D sessions I have ever been a part of, utilize a "board" to help visualization. This has been going on since the inception. If you don't believe me, or think I am "hating on D&D players", look up Essential kits, or starter kits. Some get so into it they literally make 3D boards for their stories with walls buildings etc.
