#App for drilling addition problems

Uses sudoku-like "sum grid" puzzles.

This repo is an example of a Freewheeling App, designed above all to be easy to run, easy to modify and easy to share.

#Getting started

Install LÖVE. It's just a 5MB download, open-source and extremely well-behaved.

Run the app using LÖVE.

#Hacking

To modify it live without restarting the app each time, download the driver app. Here's an example session using a different freewheeling app:

Some reference documentation on how to create your own apps.

If the app being modified by the driver lives in a .love file, your changes will go into the save directory. If it lives in a directory (like this repo), your changes will go straight into the same directory.

#Keyboard shortcuts

• ctrl+n to generate a new problem
• ``` to reveal/hide the solution (I should probably disable this before putting it in front of the kids.)

Exclusively tested so far with a US keyboard layout. If you use a different layout, please let me know if things worked, or if you found anything amiss: http://akkartik.name/contact
