Connect Sums - A Math Doodles Challenge

By Carstens Studios Inc.

This app is only available on the App Store for iOS devices.


"Connect Sums" is one of a series of challenges included in the award winning "Math Doodles" iPad app. This version of "Connect Sums" has been designed specifically for the iPhone/iPodTouch screens.

It wasn't until after my school years, that I became a lover of math. I managed to slip through all of those classes, text books, and homework assignments, without learning one of the most important math lessons of all. Math IS FUN!
I design Math Doodles to provide a place where anyone can discover the joy, wonder, and fun of mathematics.
Math Doodle challenges provide plenty of mathematical practice, within a recreational math setting. The mathematical puzzles allow users to play, explore, and experiment with mathematical concepts, while developing and strengthening their strategy and problem solving skills. Math Doodles challenges are designed to allow for multiple solutions and strategies. There isn't only one correct answer.

Select a series of values on a grid so that the sum of the selected values equal the value of the target number.
Users can choose from 25 different value representations and two levels of difficulty.


1. Solve Mode: Strategically solve the puzzle in the fewest number of moves.

2. Infinity Mode: Play as long as you wish.

3. Race Mode: Rack up as many points as you can solving puzzles, before time runs out. The timer is represented by a tab of paper that works its way around the edge of the screen.


1. Easy Mode: Selected values need not be neighbors of each other on the grid.

2. Hard Mode: To make things a little bit harder, each value selected must be a neighbor of the previous value selected on the grid.

Customer Reviews

Wish every math app were this good

If you want your kids to really get math, let them play with it! This app is a good way to give your kids an opportunity to understand how sums work... Whichever way makes the most sense to them... Numbers, dice dots, finger counting. There air so many ways to see what numbers look like ( Braille... Spanish... tally marks) its worth getting the app just to explore new ways to add! Graphics look just like the rest of the doodles apps... Great fun!

Great Brain Work

We like the hand-drawn graphics and various ways of presenting numbers. Really great concept and intuitive way of playing the game. The app works smoothly. Love all the Math Doodles apps.

Beautiful, smart and fun!

Everyone from age 4 to 100 should buy this app. Simple and brilliant and a great way to practice math sums with your kids.
