1. One prize of a US$100 Amazon voucher to one winner.
2. Entry is free: this is not gambling.
3. First to submit the closest height of the Burj Dubai without exceeding it wins. My decision is final in the event of any dispute.
4. The height will be whatever Guiness World Records deems it to be, and failing that whatever Emaar deems it to be.
5. Prize is by email, so you will have to verify yourself through your blogger profile.
