"Daren says that he “designs Math Doodles to provide a place where anyone can discover the joy, wonder, and fun of mathematics.” My family would say that he’s succeeded in doing just that."
- The iPhone Mom

"Beautiful, fun, and engaging! I think it is a must have for a classroom set of iPads, and it's a beautiful example of what math games should be."
- Game Lab Mom

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.

This version of "Math Doodles" introduces four challenges plus an additional functional sneak peek challenge that will be made available in it's finished form in a future free update. Each Challenge provides 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.


1. Sums Stackers: Values are piled into three stacks. Each stack is randomly assigned a target sum. Move values and sets of values around with the tip of your finger from stack to stack until the sums of each stack equal the target sums represented at the bottom of the screen. The values can be represented in 22 different ways that vary in their level of abstraction: preschoolers might start with the fingers, dice or ringlets, because they can be easily counted, while older children or adults can find a challenge with coins, roman numerals, the word spelled in Spanish, or even binary.

2. Connect Sums: Users develop their number sense by trying to clear series of random values presented in a 4x4 array. Selected values are cleared when their sum equals the target sum. Users can choose from 22 different value representations and two levels of difficulty.

3. Unknown Square: Users begin to explore algebraic thinking by developing strategies to solve for unknowns found in a 3x3 array of values. Horizontal, vertical, and diagonal sums for the values are shown.

4. Splat Go Round : Users develop an understanding for rotations by experiencing math in action. Users rotate a fly swatter to splat a target fly. Users can choose from several rotational modes including clock hours, clock minutes, angles, and fractions.

5. Sneak Peek Challenge - Pattern Twist : Develop spatial visualization of patterns while solving this Math Doodle puzzle.


1. Solve Mode: Strategically solve five random sets 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.

Each challenge has an easy mode and a hard mode:

Love it, love it, love it!

We moved schools and needed an engaging way to help my child catch up with students in her new class. You can choose difficulty along with symbols used to suit your child. It's creative, fun and best of all, my child loves it. We play together and fight over who gets to answer. She is in second grade and aware of anything that is too babyish. It's bright and entertaining for children without being too childish. It also covers content for older children, and some content, I even find challenging. Very flexible app! Hands down one of the best apps I have ever downloaded. Love it, love it, love it. Worth every penny and more!

Gorgeous and mathematically visual!

I'm a fourth grade teacher, and I can't tell you how awesome this is for visually seeing the operations and processes for addition in numbers, but with hours, minutes, angles, and much more. The graphics are simple and cool, with rich and engaging colors. I love this app!

Math Doodles is great

We’ve loved playing Math Doodles, Sum Stacker, and Symmetry Shuffle since we got our first iDevice. The hand-drawn graphics are so much fun, and the concept is so unique and challenging. Highly recommended for your app library!
