Hi,
So this one seems to be rather new. I don't even think it's on apple vis yet.
Lost cities is basically a card game, focussing on strategy. You have five lanes - red, blue, yellow, green and white, and you have to place cards into those lanes. However, these lanes start at negative value points so you have to build them up. It's basically a game that ends when the draw stack of cards is empty.
The game automatically reads what the opponent does each turn, and it has both computer oppponents and online possibilities through game center. This includes around 90 achievements, but some of these are incredibly rediculous -- win 100000 games, and they have the exact achievemnts for online too, so both single and online play achievements.
It apparently has some sort of soundtrack too, but for some reason I can't hear any music when I play.
There is an interactive tutorial included near the bottom of the screen in the rules section of the app, and it can also be spoken. The rules section also has a speak button, which, when pressed, has a narrator reading the section for you.
Unfortunately, there is no AI voiceover in the game, but the game fully works with the screen reader.
