The other solution by SILVERsifDURFER is perfectly valid and works fine. However, one thing I would like to point out: the achievement description is slightly misleading. You see, the leaderboards for this game are dead - they will not load. You can't post your scores to the leaderboard either. So, if you try the demo and see that, you might think that this is an unobtainable achievement.
Wrong. The leaderboard thing is unnecessary, you just need to surpass your own score three times.
