i just cheacked Duckdice profile they are so Shady as they are described before me by other users
i should not complaint about my loses.
Its okay to make out some complaints but you should be at least knowledgeable on how odd works. No win in 100 bets on 9.9%+ chance doesnt automatically tells that they arent fair.
If you are still in doubt then test out those things in other sites with having some flashbet like wolf.bet and see it for yourself on how it do give out the same possible
outcome.
You wouldnt believe unless you have proven out to yourself.
