I got a second place with a one-liner

I run

return 2 * values[-1] - values[-2]

around 10 times. The results were very varied, but the maximum was 1403 points (2nd place). This puzzle seems very unbalanced to me, if such a dumb program can get such a good result.

I'm not sure how to fix this. Maybe giving more than 10 points will help. Or maybe we should just wait until more players participate.

PS. This reminds me of 2048 codenjoy where one of the best bots was basically return choice("LEFT", "UP") ;-)
