With most games, you can see the whole board, and physically move pieces, spin wheels, and select cards the way you would in the real world, but the medium allows more than just replicating the physical experience - it's possible to make it better. Tablets, with their large screens and tactile interface are ideally positioned to play board games. Other games like Scotland Yard or Game of Life introduced bigger boards, props, and complicated scoring mechanics as well.
When you think of board games, you might remember childhood favourites like Ludo, Monopoly, or Scrabble.
