A math puzzle where you must change the frequency of your device so that it blinks once every 10 seconds. Choose cards from the bottom to build an equation that results in 10!

This version contains:

• Three regular difficulties and one unlockable super-difficult one
• A short campaign mode with curated puzzles that increase in difficulty
• A free play mode with randomly generated puzzles

It doesn't contain:

• Puzzles where you need to match something other than 10. They're supported by the code, but not the theme :)
• Mobile device / small screen support

Hint: if you get stuck, you can find the solution to the current puzzle in the console.
