Edutainment is always iffy business. The problem with this is it is trying to make a game out of doing algebra. In the end the only point of this is doing algebra.

Contrast this to something like Kerbal Space Program. This is a game about shooting rockets to other planets. In playing KSP, I've learned a bunch about orbital mechanics, which is the quite obvious result. If you were making an edutainment game to teach about how to work with orbital mechanics, it would look like KSP.

But the secret thing that the game has done is make me revisit calculus. You have a rocket that has a certain force at sea level, a certain force in the upper atmosphere, you have a mass that is a full tank of fuel, and a mass that is an empty tank of fuel. You have aerodynamic drag that changes with the density of the atmosphere.

It gives you some information, and you can go and get mods which give you more information (and expose you to more of the math, but at your own request). Or you can do what I did and take experimental data and build your own model.

But when I'm doing this it's not to balance an equation. It's because I want to get a rocket to the Mun, it's because I want to build the cheapest ship that can take space tourists up and down to fund my space empire. It's because I want to build a base on a distant planet. It's just that in order to do that, I learn me some calculus, and some orbital mechanics, and some other things until I can break some of it down in my head, until I'm talking about thrust to weight ratios, delta v, specific impulse etc. like they're no big deal.

A game like dragonbox falls into the edutainment trap. It's a game about balancing an equation on either side of a playfield. It's too abstract. It's just doing math problems with pictures.

It's like all the different typing tutors that we were given in computer class when I was growing up. Even the most gamified ones like mario teaches typing, or later typing of the dead, were still typing tutors.

But what really improved my typing speed more than any typing tutor out there was when I started playing Everquest online, and later World of Warcraft. Because in those games, before voice comms were common place, you had to be able to communicate reasonably effectively, but quickly, and in the middle of doing other things.

I wasn't typing to get points typing. I was typing on the way to do things that I enjoyed. Nobody would sponsor a World of Warcraft class to teach typing, first of all it wouldn't necessarily be effective, how much you type depends on the individual, plus it wouldn't be particularly fast, and it would be impossible to test on.

But we don't learn things well by learning them fast and then dropping them. We learn things well by being engaged in them and repeating them frequently over a long period of time. KSP will do good things for my calculus, because there's a lot of space to cover in that game and it's fun to explore space. A game like dragonbox is not interesting enough to say a year after finishing the challenges "Ah man, I really want to pick that up again and play through it again." it doesn't engage your imagination, it doesn't give you any context except "Solve this disguised math problem and get a gold star"

edit: All that said, I'm still happy the program exists, and I hope it does well. I do think it takes the wrong approach, and I do think that edutainment in general really misses the mark, as does the current "gamification" trends we're seeing around other places. That said, I don't think it would do harm, and it will definitely expose kids to algebra in a way that could definitely help them.

I guess my point is more that sometimes the better way to teach is to do it more indirectly. If another game that was really interesting on its own merits allowed you to excel by figuring out algebra, that game is a more organic way of learning, and it also makes the subject matter more meaningful. It's also incredibly hard to measure or predict it's efficacy, so you can't really sell it to parents as a way to teach algebra any more than you could sell WoW to parents as a typing tutor.
