That was fun once I figured it out! Broke 900 on my second attempt. My first attempt involved me losing before I matched anything because I didn't know what to do. Then I read the instructions in the comment and had a blast. Amazing how fun a simple puzzle game could be. It got challenging at 700+. http://i.imgur.com/RBgqKYS.png http://i.imgur.com/RBgqKYS.png I can't play anymore after the surprise though. It won't let me merge 3 and 4. Possible bug or does the objective change? I saw multiplication but nothing multiplies to a prime so I couldn't figure it out. Was I supposed to take 2x2=4 and 1x3 = 3 and then take 3+4 for 7? That was my only idea but I stopped. http://i.imgur.com/0yEr0ig.png http://i.imgur.com/0yEr0ig.png
