In the game, the player is asked a question (identification, capital, national landmarks, etc.) and if they choose the correct answer from four multiple-choice options they can use that state for their stack. The object is to stack enough states to reach the finish line, but gravity applies so it can be quite tricky, and if your stack goes wrong, states go tumbling. While testing, I caught myself saying "Oh no...there goes Montana."
If the player reaches the finish line with 60 percent or more correct answers, they "win" one of the 50 states, which is then added to their map. As more states are added, three bonus games, Pile Up!, Puzzler and Capital Drop, are unlocked. The additional games are also terrific and provide children motivation to keep going.
Different children can play at the same time and have their own individual gameplay saved under their name. The animation and sound is not extensive but works perfectly. A simple thing like eyes and a mouth makes the states seem so much less boring.
The only thing I found missing is Stack the States is a small feature in Dan Russell-Pinson's Stack The Countries app. With each background image in STC, there is a label describing what it is and where it is, such as "The Great Wall Of China - China."
That's a small item, however, that I'm sure can be added in a future update. This is a terrific, inexpensive app for kids AND adults who may not remember these things quite so well. :)
There is also a free demo to try before you buy.
