Hello @uhatgaming, I'm not going to be able to participate in your contest due to lack of time at this moment. I do support your cause though so i would love to share some idea's for contests with you.
A contest about your own stream. People would actually have to watch your stream live and pay very good attention to the hints you give. Combining those hints, they should have the answer on a question which you would ask them for the contest. This way, the people who actually follow you closely have a better shot at winning.
You could play a free to play game and challenge your followers to reach a certain score or do a certain play and clip that. The people who would achieve the goal you set for them, would receive a prize.
Hope this helps you out, good luck and i hope to join u soon on dlive. I'm thinking about streaming professional gaming tournaments from the ps4 where i will participate in.
These are some good ideas, it would be a great way to engage with the viewers indeed.
