I would like to try your games is there a faucet or play coins you have on your website to test your games if none I'll try to deposit few coins?
It is clear from the title of this thread "LuckyDiamond.io 🎲
Big faucet 🎲 Diamond rains 🎲 Hourly contests". Sure there is faucet that you can claim to try the game before you decide to make deposit. There is also rainbot in chat where you can get some free coins.
and when will the mine and roulette game will open? I'd like to try that too.
It is coming soon so you can expect that you will not need to wait for too long time. Follow their social media accounts so you can get early notification once the games are ready/launched.
