No easy way to see if you actually won. I might be reading this wrong but if you won you won't receive your reward for another month.
From the ticket page:
※Notice※
※Regarding the distribution of the Nutaku Gold; participants will be able to claim their rewards upon logging in and completing the tutorial after the official release.
※Participants who completed the tutorial will be able to collect their Nutaku Gold beginning one month after the official release.
※Nutaku Gold rewards must be used within 1 month of receipt.

So beginning one month after completing the turorial. So a month from now you can collect it if you won? Ifso maybe some of us might still have won. No easy way to check with that giant wall of numbers.
