Written with vanilla Javascript, CSS, and HTML, this pen is a clone of the famous 2048 game. The goal of the game is to get a box with a points value of (you may have guessed it) 2048. To play, either use arrow keys or swipe gestures to move the boxes around the grid. If two boxes with the same points value collide, they will combine into a single box with double the points.

Developed as a proof-of-concept for a larger app, this CodePen is meant to help you (or more specifically, me) play along with the chord changes from over 1,000 jazz standards. Simply select the desired song from the dropdown, set the BPM which you want to play at, and hit Start. If I do say so myself, it's a great learning tool. You'll probably want to view this in Full Page Mode.
