Great math tool! Hope they plan to produce more apps like this one. Great Job! ### 5/5 — Great educational game! *2009-11-09* Great tool for helping with numberline comprehension. ### 5/5 — Can you find the Black Pearl? *2009-11-06* This game is an excellent way to teach the concept of the number line! The levels gradually get more complex, allowing you to completely master the number line. The bonus games are fun, too! Overall, this game is a great educational tool that is really fun to play, as well. ### 5/5 — Amazing! *2009-11-05* This game is exactlly what I was looking for, and it looks fantastic. Great job, I highly recomend this educational game. ## Most critical reviews (10 lowest-rated) ### 1/5 — Black screen on iphone5 *2015-11-06* With music and some obscure graphics on the side - please fix!!! ### 1/5 — It's ok *2009-12-11* This app is pretty much a waste of time. ### 2/5 — Great idea - lousy quality *2011-10-26* This is a great idea, but execution is badly in need of improvement. The first few seconds on every level are wasted as the screen is blocked by an unnecessary message. That info should be in the tutorial or even learned by error. There are the levels where the target numbers are too small to read (the font is fuzzy in the numerators of fractions.) The knife is about 500 pts. wide with no indication of where it will cut. Once you cut the eel using the ruler, the scoring shows targets that are off when measured by the ruler provided. The worst mistake is on the last couple levels where a target of 11/2 is displayed as 1/2 - there is no way to know whether the first digit was dropped by programming error or if the target really is 1/2. An educational ap should not have such a gross error. ### 2/5 — Huh? *2011-03-23* Yay! Let's all have fun with fractions! NOT! What is the point of this game, seriously! ### 3/5 — Math,ouch!! *2010-02-01, version 0* Good game after the first screen. ### 4/5 — Nice free learning game *2011-01-29* It's a fun game for the kids to learn fractions on. Would have been nice to have a few more levels and the ability to control the difficulty, but maybe that will come with the paid version. ### 4/5 — Nice to see an educational app that is also a fun game *2009-11-11* My 6-year-old really likes this game. But the difficulty level progresses too fast. It would be nice to be able to choose which math concepts to practice, e.g. positive whole numbers, negative numbers, fractions, etc. ### 5/5 — Learning the Number Line *2014-07-03* My 6-year-old enjoys the first few levels of this game and has played it many times. The later levels with fractions and negative numbers are pretty fun too. Definitely can see how it would help kids practice the number line. ### 5/5 — Great *2014-05-19* This is a great game why is there no comments. ### 5/5 — Pearl diver *2012-10-05, version 2.1* This app is brilliant for learning decimals plus and minus numbers. Highly recommend it for children , they enjoy playing it. ## Most praised reviews (7 highest-rated) ### 5/5 — I love math *2011-12-26, version 2.1* My school just go iPad 2s and it had this game I really liked it so I got it on my phone ### 5/5 — Horrible game *2011-06-12* Every time I dive it said I got a boot I only got the pearl one time you'll need to fix it. ### 5/5 — Pearl diver's awesome! *2011-05-02* It teaches me a lot! ### 5/5 — Practice that number line! *2010-05-19* This is a fun way for kids learning fractions and the number line to practice what they are learning. It's not a particularly deep game, if you'll pardon the pun, so if you're looking for an intense gaming experience, you're better off looking elsewhere. But if you're looking for a fun math-based diversion, or need to practice your number line and fraction ordering skills, this is just the ticket! Nice graphics, fun gameplay, and good production values. ### 5/5 — Brilliant Maths Game - and it's free! *2010-04-20, version 0* Really nice interface, but actually some nice tricky maths work too! A fun way to learn about fractions and mixed numbers - I'm a teacher and I loved it. Bet my kids will too. Some of the free education apps are a total waste of time, this one is fun and educational. ### 5/5 — Mom *2010-02-04* My son is a homeschooled 4th grader & I am packing my iPod touch with educational games for road trips. This is the best math game i've found so far. And for free it really can't be beat. I hope the company creates more!!! ### 5/5 — Pearldiver *2010-01-02* Amazing game! Great for stimulating those mathematical corners of the brain that are oft neglected. Highly recommended!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
