Howl.gg is a new RUST skins gambling website launched 1st April 2021. Although running so short it has a big and active player base. Website's design is clean and responsive.
Howl.gg offers Jackpot and Coinflip games.
Howl.gg has a provably fair, so results of each jackpot, coinflip rounds and giveaways can be verified. It is generating their own server seed and they are using random.org to generate second seed. Both these seeds are used to generate winning percentage. The hash of both seeds combined is given, which can be used after the round ends to check if the results are matching by generating new hash from revealed seeds and compare it to the hash given at the start of the round, if it matches with a newly generated hash, then results were not changed.
You can read more about their provably fair system here:
Howl.gg is offering hourly giveaways which can be joined by everyone (not only depositors). In each giveaway you have a chance to win RUST skins. These skins are around $3-10. The only requirement to join is to have "howl.gg" in a steam nickname. On the more expensive giveaways ($20+), you have to wager over $50 in the last 7 days to join.
Howl.gg offers support through a live chat. All you have to do to contact them is to click on the "Support" tab and support chat will open.
