Stack the States. By answering questions about the U.S. states and stacking up the correct answers, the player wins states on a map. Questions range from easy (choosing the state that matches the abbreviation) to hard (knowing state nicknames). The bar moves up as you get better so you continually have to earn more states to more to the next level. There are bonus games that open up that are fun too - T's favorites are puzzler and capital drop (in which you have to match state shapes with their capital cities).
A sample question with states already stacked.
The goal is to have the stack reach the black and white line.
The "My States" page. Each time you stack states up to the bar, you earn a state for the "My State" map.
In one of the bonus games, Puzzler, you drag the states together to make a section of the map.
The app costs 99 cents and is worth every penny. If you play it long enough, it repeats questions, but this doesn't bother T since he loves repetition! Check it out at the itunes store here.
T's new favorite game is Presidents vs. Aliens. Created by the same guy as Stack the States, players earn presidents by answering questions about the men who have served in the highest office in the U.S. This a bit more difficult than the states but the tougher questions have clues (like dates) that help. The hardest ones are quotes from Presidents as not many of them are well-known. [We might engage in a bit of quiz-jacking.]
A sample question - in the background, you can see the aliens hovering over Washington, D.C.
After you get a question right, you get to help the President take out some of the aliens. When all the aliens are defeated, you win a president for your big "My Presidents" list.
The main "My Presidents" page. In the bottom corners, you can see the bonus games: Heads of State and Executive Order. T loves putting all the presidents in chronological order in Executive Order.
