The parents' guide to what's in this app.

Educational Value

Kids can learn basic math skills as they match similar numbers (along with 2 and 1) to advance in the game. Threes! isn't really a math game, though. It's about learning to look at the board and strategically decide what your next move should be to stretch out your playtime. Matching numbers is important, but users also have to keep an eye on what's coming up and where that number might go. Kids exercise some basic math with Threes!, but the real value is the strategic-thinking skills they'll practice.

Ease of Play

Although the game itself is challenging, grasping the concepts of how to play is very easy.

The app has ads for the Threes! soundtrack and the Puzzlejuice app.

What parents need to know

Parents need to know that Threes! is a math-based puzzle game that borrows elements from both Sudoku and Bejeweled. It encourages not only math skills but also strategic planning to maximize your playtime before you run out of possible moves. It's an easy-to-learn, tough-to-master game that kids and parents both will love, but parents should be aware that the app includes links to social media and the app store.

What's it about?

Users slide numbered tiles around a four-by-four grid, matching up multiples of three, which create bigger numbers and a higher score. When users can no longer combine numbers, they'll see their scores.

Is it any good?

Hit games come and go in the app stores, but, if there's any justice in the world, THREES! will have a long ride. It's not simply smart, challenging, baffling, or funny -- it's also utterly addictive. It's a math game that doesn't require a lot of calculations, and it's a matching game that doesn't dumb itself down with cartoonish images. 

The lure of building bigger and bigger numbers is powerful and will keep you coming back. And if that, for some reason, doesn't do it, seeing your friends talk about their scores on social media (or seeing them in Apple's Game Center) will spur you to try harder. As with the best games, it's easy to understand but hard to master -- but that won't stop you from trying to do so.
