Stack the States® 2

Review by eFreeware

Stack the States 2 is an educational geography game from developer Dan Russell-Pinson, and it is built around a simple idea: answer questions about the United States, then physically stack the states you earn until your pile crosses a checkered line. It costs $2.99, carries no third-party ads and no in-app purchases, and has been on Google Play since August 2016, with an update in late October 2025. It holds a 4.6 average from 472 ratings, and the install count sits above 10,000.

The main reason to consider it is that the learning and the playing are the same act. You are not sent to a separate quiz screen and then rewarded with a mini-game; the states you identify become the blocks you use to solve the level. For a parent or teacher looking for something that teaches capitals, shapes, flags and landmarks without feeling like homework, that structure is the selling point.

It is also a paid app in a category where free alternatives are everywhere, which shapes who it is for. There are no ads interrupting a child mid-question and no purchases to explain or refuse. You pay once and the whole thing is there, which is a meaningful difference for a game meant to be handed to a kid.

What separates it from a plain quiz app

This one borrows the physics-toy appeal of a stacking game: the states are animated, and you can touch, move and drop them anywhere on the screen. That tactile element matters more than it sounds, because a wrong answer still leaves you with a state-shaped object to place, and placement is its own small puzzle.

The second difference is the collection layer. Every level you finish earns you a state, and those states accumulate on a personalized map of the United States. The goal of collecting all 50 gives the whole thing a spine that a series of disconnected quizzes lacks. Progress is visible and cumulative, which is the kind of feedback that keeps younger players coming back.

There are new question types, a voice mode, 3D graphics, ten different 3D scenes set in various locations around the country, and models of more than 90 US landmarks. Each state's map now includes a 3D elevation view and its main cities. That is a lot of content for the price, and it is the sort of thing that makes a paid educational app easier to justify.

How a level actually works

The loop is straightforward. A question appears about a state's capital, city, shape, landmark or flag, and a correct answer earns you that state as a piece. You then drag and drop the animated state onto your growing stack, aiming to reach the checkered line at the top. Miss and you get another question, so the quiz keeps feeding the stacking rather than interrupting it.

What I like about this design is that it rewards two different skills. You need recall to answer, and you need a bit of spatial judgment to build a stable stack. A player who knows the capitals but stacks carelessly can still struggle, and a player who is good at the physics still has to answer correctly to get pieces. That combination is what makes it more than a memorization drill.

Finishing a level adds a new state to your map, and the map is the long-term record of how far you have come. There are 50 flashcards, one per state, and hundreds of unique questions, so the question supply is deep enough that repeat play does not immediately become repetition of the same facts.

The bonus games and the voice mode

Together with the main stacking mode, that makes four games in one package. The unlocking is tied to progress, so the extras arrive as rewards rather than as a menu of options at the start, which gives younger players something to work toward beyond the next level.

The feature I would single out for families is voice mode. It helps non-readers play independently, which is a real practical problem with quiz games aimed at early elementary ages: if a child cannot read the question, an adult has to sit there and read every prompt aloud. Voice mode changes the game from a shared activity into one a young child can run alone, and that is a significant difference for a parent trying to keep a kid occupied productively.

The 3D presentation supports the same goal. Ten scenes depicting different locations in the US and models of over 90 landmarks give the questions visual context, so a landmark question is not just an abstract name. The interactive map with its city labels and elevation view serves a similar purpose, turning the map from a scoreboard into something worth exploring.

Profiles, privacy and the practical details

The app supports up to six player profiles. In a household with more than one child, or a classroom tablet passed between students, that means each player keeps a separate map and a separate collection. It is a small feature that makes a big difference in how usable the game is in shared settings, because progress is not overwritten every time someone new picks up the device.

On the privacy side, the developer states that the app contains no third-party ads, no in-app purchases, no integration with social networks and no third-party analytics or data collection tools. The app has no ads, though it does point to the developer's other Google Play titles. For parents who care about what a children's app is doing in the background, that combination is about as clean as the category gets.

The app is rated Everyone and described as educational. It is a paid download at $2.99 with no ads and no purchases inside it, so the cost is a one-time decision rather than an ongoing one. The most recent update, in October 2025, was described as miscellaneous bug fixes.

Where it fits in a household or classroom

The clearest fit is a family with elementary-age children who are starting to learn US geography, especially if a younger sibling wants to play alongside an older one. Voice mode lets the non-reader participate, the profiles keep everyone's progress separate, and the stacking mechanic gives the whole thing a toy-like quality that quiz apps usually lack.

Teachers with a small set of classroom tablets would find the same features useful, particularly the six profiles and the absence of ads. A game that stops to show an advertisement every few questions is hard to hand to a student, and this one does not have that problem. The map and the landmark models also give a class something concrete to talk about beyond the answer itself.

Older students and adults who simply want to brush up on state facts will find the content solid, though the presentation is clearly built with younger players in mind. The stacking element is the point here, not a wrapper around it, so anyone hoping for a pure reference or flashcard tool should weigh that. What this is, and what it does well, is a game that teaches geography by making the states themselves the pieces.

A paid geography game worth the one-time cost

Stack the States 2 earns a recommendation for families and classrooms that want US geography practice wrapped in an actual game. The stacking mechanic gives correct answers a physical payoff, the map and the 50-state collection provide long-term goals, and the bonus games extend the package beyond a single mode. Voice mode and six player profiles make it workable for young children and shared devices alike.

The $2.99 price and the absence of ads and in-app purchases are central to that recommendation. You are buying a complete, self-contained game rather than a free download with prompts inside it, and for a children's app that is often the deciding factor. The 4.6 average from 472 ratings suggests that buyers have generally been satisfied with what they got.

If you are looking for a geography game to hand to a child without worrying about what else comes with it, this is a strong candidate. If you want a serious study tool or a reference for state facts, the game framing will feel like more than you need. For its intended audience, it does the job it sets out to do.
