EdgeMates is a fun, new way to help quiz you on the capitals of the world.
The object of the game is simple. A series of tiles are created that have either the state or city on each side. Your goal is to place the tiles on the game board so that each country matches up with its city on the connecting edge-its “edgemate”.
Three different levels of difficulty are available - 4, 9, or 16 tiles. Try the easy level to get comfortable with the game, then move on to the more difficult levels. Dont kid yourself--even if youre a geography whiz, the game is a real challenge!
