Editors’ Notes

Imagine a strategy game crossed with an math primer, and you’ve got DragonBox Big Numbers. By trading apples and other resources, kids can explore a gorgeous landscape as they learn addition and subtraction concepts. We’re impressed by how seamlessly the app combines play and learning. From drawing digits to solving ingenious visual math problems, numbers are fun in countless ways.

Great game, but ...


This is an entirely addictive game, and adults will enjoy it as well as children. However, I wish there was a way to close the addition/subtraction window, as it's way too easy to accidentally open it (for example, while collecting bees), and then you can't close it without doing the math. In the mean time, all the rest of the bees are flying by and you can't catch them because the other window is open on top. Similarly, if you accidentally select to trade your bees for honey instead of your fish for ice cream, you can't leave the trade window, you have to complete the transaction first. Please let us close the windows and I'll happily give this a five star rating.



This game starts off slow but give it a bit and it becomes extraordinary. My 6 and 8 year olds are mesmerized and simply can't get enough of it. Meanwhile they are learning tons of math. One of the very best apps I've come across. Seriously, try it out!
