 [MathSwipe](http://sf-interns.github.io/mathswipe/) is a `CoffeeScript` game developed in the context of the [Originate](http://www.originate.com/) 'Intern Hack 2015' Event, presented August 2015.  It is a web-game in which the user is given a grid of numbers (0-9) and operators (+, -, ×). The user's goal is to swipe a path through the cells to create an expression that evaluates to one of the goal-values listed below the board. A level is completed when the user finds expressions evaluating to each goal-value and has cleared the board of all cells.
 
+Math Swipe is a simple brain game that is rooted in math. From children to their parents, Math Swipe is simple yet challenging enough to stump even the strongest math wizzes.
