There is a
basic computer solo version of Limes available. It doesn't have the actual game graphics so it strips it down to a true abstract but it's functionally the same game.
I scored 45 on my first game, playing without the diagonal variant (which I always play with in my tabletop games of Limes), which is not bad. It was a bit hard to get used to the artless cards, since the Roman frontier theme is what drew me to the game in the first place.
