In "Stack the States," players build tall piles by correctly identifying outlines of the 50 U.S. states. The player successfully completes a level and receives a random state on a personalized map after the pile of states grows taller than the checkered line. Players can unlock free bonus games, including "Map It," "Puzzler," "Pile Up" and "Capital Drop" by completing higher levels in the game.
In "Map It, players attempt to complete a full map of the United States by tapping the correct location of the selected state on a map. "Pile Up" and "Capital Drop" are both fast-paced games that encourage players to identify states and match them with their capitals. "Puzzler" is a more relaxed game in which players complete a full map by sliding states around like pieces in a jigsaw puzzle.
"Stack the States" comes with a full set of 50 state flash cards and uses multiple choice questions to teach kids basic geographical concepts. The game also features information about state flags, nicknames and abbreviations, and it includes photos of many notable U.S. landmarks. It is recommended for children ages 9 to 11. The game is available for iPhone, iPad, Windows computers and Windows Phone.
