To create your own 1,000x entry: 

1. Make sure you have made at least one deposit into your Dabble account to be eligible (you can deposit funds using Visa, Mastercard, Discover and Apple Pay) 
2. Select MORE or LESS on 12 player projections
3. Place your entry fee, and if you get them all right you can win up to 1,000x your entry fee (i.e. $5 -> $5,000) 

You can see the full payout structures in Dabble's Game Rules.
