Xumbers is similar to Scrabble, but uses numbers instead of letters. Here are some users’ comments: “really, really fun”, “makes you think”, “kind of addictive”, “playing games, having fun and getting kind of competitive with math”.

When playing Xumbers, your goal is to create Xumbers Words (the longer the better). Xumbers Words are collections of digits in which the number represented by the last one or two digits is the sum of the previous digits. For example, 426 is a Xumbers Word because 4 + 2 = 6; so is 42612 because 4 + 2 + 6 = 12.

Xumbers has two modes. In Solo mode you play against your device in one of three levels:
• Beginner (for kids),
• Intermediate (use higher math skills)
• Expert (wickedly difficult).
In PnP (Pass and Play) mode, you compete against another person passing the iPhone or iPad back and forth.

Re-energizing my brain!

Great app and lots of fun to play. I had gotten away from doing simple exercises like this to keep my brain stimulated. This sure does the trick. I play it both on the iPad and iPhone and it works well on both. A++ and well worth the cost to help out the developer.

Addicting fun

Xumbers is a great game. It is similar to scrabble but with numbers. The three levels allow for a wide range of math skills. I play the beginner level with my son who loves figuring out the addition possibilities. The expert level is quite challenging. Definitely worth the money.

Xumbers is a wonderful fun game. Great for the kids to use as a learning tool and the great thing is they will want to play it! A great value!
