The challenge was: how long will it take to write a JavaScript Tetris clone, stranded on a desolate island with only an old laptop and a painfully slow and unreliable mobile internet connection, and in addition barely possessing mere basic JavaScript knowledge? The answer: two evenings and one morning.

At first I used a list containing the locked blocks in order to be able to render them more quickly (in contrast to looping through the 10*16 'blocks' matrix), but maintaining the list when deleting rows showed to be a bit tricky.
