Learn English w/ Grammar Games

Review by eFreeware

Most grammar apps spread themselves across the whole language. Preposition Master does the opposite: it takes one small, stubborn piece of English — the little words that sit before nouns and gerunds — and builds an entire game around placing them correctly. That narrowness is the most interesting thing about it, and it is also the reason it exists at all. Prepositions are the part of English that trips up learners long after they can hold a conversation, because the rules are less rules than habits.

The game comes from Gamiak and is sold for $6.49 with no advertising and no in-app purchases. It has been on Google Play since August 2017 and carries a 4.3 average from 479 ratings, with more than 50,000 installs. The developer describes it as designed and developed by educators, and the structure reflects that: a set of levels, a scoring system, and a clear idea of what the player is supposed to get better at.

If you are learning English and want a focused drill rather than a broad course, this is built for you. If you are teaching, or helping someone else study, the level structure gives you somewhere to point. It is not a general language app and does not pretend to be one — it is a puzzle game with a grammar obsession.

One grammar point, taken seriously

The premise is simple enough to explain in a sentence: each level gives you a sentence with gaps, and you place the prepositions where they belong. What makes it more than a worksheet is the framing. The developer calls it the first game of its kind built entirely by educators, and the level names suggest a deliberate progression rather than a random pile of exercises.

That progression runs from Beginner, where sentences are short and carry the fewest prepositions to sort through, through Competent and Professional, up to Expert, which the developer pitches at people with the most proficient English skills. A fifth level covers proverbs and sayings, which is where the game stops being purely about grammar and starts touching idiom. That last level is the one I find most appealing in principle, because fixed expressions are exactly where preposition knowledge becomes invisible to native speakers and maddening to everyone else.

The one-time price, with no ads and no paid hints, matters here. A drill game lives or dies on how often you are willing to return to it, and a paid app with no interruptions is easier to treat as a study tool than something that stops you mid-sentence. That is a judgment about the model, not a claim about how the game plays.

How a round works

Each level presents sentences with prepositions missing, and your job is to put them back in the right slots. The developer keeps the pressure on with a time penalty for tapping the wrong preposition, so a round is not just about knowing the answer but about committing to it. Guessing your way through is possible, but it costs you.

When a sentence is finished you get a score built from two things: how quickly you worked and how many errors you made. That combination is a sensible way to reward both accuracy and fluency, and it means a careful player and a fast player can both do well, just for different reasons. It also gives you a reason to replay a level you have already cleared, since a clean, quick run scores better than a slow, messy one.

The recent 2.0 update added a new design along with new quizzes and exams, so the content has grown beyond the original level set. Classic Mode, added in version 2.1, plays as a plain sequence of levels. For anyone who prefers a clear sequence over a mixed menu of activities, that mode is likely to be the default way in.

Playing against other people

The game includes an online multiplayer mode, and friends can play against each other. That turns a solitary drill into something closer to a quiz match, where the same preposition knowledge is tested under the added weight of another person working at the same time. For learners who find solo practice hard to sustain, that social layer is the feature most likely to keep them coming back.

I would treat the multiplayer as a bonus rather than the main event. The competitive mode is there for the days when drilling alone feels like a chore.

The levels, and who each one fits

Beginner is exactly what it sounds like: the simplest sentences, with the fewest prepositions to choose between. Someone who has studied English for a few months should be able to make progress here without feeling lost, and the limited set of options keeps the guesswork manageable.

Competent is the point where the difficulty rises, aimed at learners who are further along. Professional is aimed at students with a solid base who want to keep their skills current — the kind of person who reads English comfortably but still hesitates over whether a train arrives in, at or on a platform. Expert is reserved for the most proficient, and the Sayings level sits alongside the difficulty ladder rather than on it, teaching popular idioms and expressions as whole units.

That spread is the strongest argument for the app. A learner can start near the bottom and move up as the sentences get longer and the choices get tighter, which is more or less how you would want a grammar drill to be organized.

Who it suits

The clearest fit is an intermediate learner who can already read and write English but keeps getting prepositions wrong in ways that mark them out as a non-native speaker. That is the specific frustration the game was built around, and the level names map onto it directly. It also suits someone preparing for an exam or a proficiency test who wants short, repeatable practice rather than another long course.

Teachers and tutors could reasonably use it as a warm-up or a homework task, since the levels give a natural way to assign difficulty. The Sayings level has a second audience too: anyone who wants to pick up common English expressions and remember them, rather than learn them by accident.

It is a paid app at $6.49, with no ads and no purchases inside it, so the decision is a single one made before you start. The level descriptions and the 4.3 average are what you have to go on. For a game this focused, that is a fair amount to go on — you either want preposition practice or you do not.

What to weigh before paying

The main thing to be honest about is the scope. This is a preposition game, not an English course. It will not teach you vocabulary, pronunciation, listening or verb tenses, and it does not claim to. What it does, it does in one direction, and the value you get depends entirely on whether prepositions are the part of English you currently need to work on.

The time penalty for wrong answers is worth thinking about as well. It is a good motivator for someone who already knows the material and needs speed, but a learner still forming the rules may find that being rushed encourages guessing. The scoring rewards both accuracy and pace, so there is room to play carefully, but the penalty is part of every round.

The game has been updated as recently as August 2026, which suggests it is being looked after rather than left to sit. None of that tells you whether the sentences will match the English you actually use, and that is the one thing no store page can settle.

A focused drill for one stubborn grammar problem

Preposition Master is worth the $6.49 if prepositions are the thing standing between you and confident English. The five-level structure, the scoring that rewards both speed and care, the multiplayer option and the idiom level together make a more complete package than the single-idea premise suggests. The 2.0 redesign and the 2.1 additions of Classic Mode and cloud sync show a game that is still being developed rather than merely sold.

I would point it at intermediate and advanced learners first, and at teachers looking for a level-based grammar activity second. The early levels suit complete beginners, while the later ones are aimed at learners who already have some English behind them, and the app concentrates on prepositions rather than on English as a whole. As a paid app with no ads and no in-app purchases, it asks for one decision and then leaves you alone to practice.

For the right learner, that is a clean arrangement: a small, well-defined skill, drilled until it stops being a problem.
