English grammar game app / Available on the iPhone and iPad

SenGram is an iPhone and iPad language game which presents pre-prepared sentence diagram puzzles and solutions to those puzzles, for players to solve.

(Please note: this is an educational sentence-diagramming puzzle game, it is NOT a tool which will solve your homework for you...).

This puzzle game tests and improves your ability to take sentences apart, identify the underlying grammatical structure, and reflect that structure on a diagram.

This game will be of interest to students of language (including ESL students), lovers of language and grammar, those sitting standardised tests with a grammar component (e.g. SAT, GMAT, NAPLAN) as well as those who are familiar with sentence diagrams and enjoy completing them as puzzles. The game might be especially useful to those students who are are currently studying a course in which sentence diagramming is used as a teaching tool.

Great App
by Beezer88 - Version 1.00 - Aug 11, 2012. This is great for teaching how to diagram a sentence. Keep developing!!! :)

This application has been used to great effect in my classroom. Used as part of the daily warmup, my kids are becoming so efficient at this oft forgotten skill. 5 stars and a hip-hip-hooray for this app.

by GhostGame123 - Version 1.00 - Aug 9, 2012. I teach Latin and a major difficulty is getting the students to see the structure of sentences. The problem, at least in part, is that they don't (or can't) see structure even in English--no one teaches diagramming any more. I'm going to try to incorporate this into this year's classes. Thanks; I'd certainly buy more elaborate versions or buy upgrades in app.

Love it!

Please continue to develop. Great aid to learning. Thank you.


Your objective when playing the game will be to place each word in the 'puzzle sentence' in its correct place on the 'sentence diagram'.

At present the app includes over 100 sentence puzzles, including:

(1) Subject and verb: 20 sentences.
(2) Article, adjective, adverb, possessive: 21 sentences.
(3) Prepositional phrase, adverbial noun: 20 sentences.
(4) Object - direct, indirect: 20 sentences.
(5) Linking verb: 20 sentences.
(6) Co-ordinating conjunction: 12 sentences.
(7) Challenge puzzles: 10 sentences.

In addition, there are further puzzles for purchase within the app in the 'SenGram Store'.

The style of diagram adopted in this app is known as the 'Reed Kellogg' style, and there are many websites and books devoted to it. In our view this style of diagramming offers one of the more enjoyable ways to test and improve your knowledge of grammar, especially if you have a visual mind.

Best of luck! We hope you enjoy the puzzles!

I think this is a great tool. It is a game and not a sentence diagram generator although that would be way cool. From reading the reviews, I see there is a great need for an actual sentence diagram generator. It is clearly stated in the app description that thins is a game. It’s ironic that people who wish to write their own sentences didn’t read the description but chose to write a negative review. 🤣🤣🤣 It looks like there is money to be made the only question is, “Who’s going to make it?” The app I mean. Thank you, SenGram for responding so positively to my email. You made my day. 🤗🤗🤗

Thank you so much for your lovely review, and for your helpful comments!


My kids enjoyed it.

I purchased this app to have my middle school son play. I wanted him to gain an understanding of various sentence structures. My hope was that it would help him with his writing skills. My son loves puzzles and has really enjoyed the app. I am frustrated that I spent $4 and the puzzles included in the price we’re completed within two or three days. Having to purchase additional content doesn’t quite sit right, and given the limited number of sentences, I don’t believe it’s worth it.

Not enough content

The app is good for reviewing grammar, but less so for newbies. There aren’t any grammar explanations or instructions. I like how easy it is to do the puzzles, the interface is simple but works well. Unfortunately, there aren’t enough puzzles, not really worth it with how little you get. You go through them quickly and you have to pay to unlock more. That might be okay if there was quite a number more, but there are only a few new topics and you can’t see what you’re being asked to pay more for.

I do really like this app, so it’s a shame there just isn’t enough content.
