Carcassonne is one of the great modern board games, and the tile-centric, competitive terrain-building affair is also pretty excellent on your phone as well. You don’t have the little squares and tiny “meeple” to strategically place as you build roads, cities, and fields, but you do have the advantage of choosing between local pass-and-play action and online competition.
When playing locally, up to six players can use the same phone or tablet, simply handing it off as turns change, plus you can fill empty spots with smart A.I. foes. And online, you can strike up an active six-player game in moments and have a worldwide turf war. It’s a well designed adaptation throughout, and the multiplayer flexibility makes it essential for board game gurus.
