KryptoGamers recently enabled playing with HIVE on all of their games. When placing your bet you can choose between STEEM and HIVE above the box that allows you to put in the wager amount. The HIVE bets are played on the Hive blockchain, the STEEM games keep being played on the Steem chain. (Note that you still need to login with your Steem account)
GAMER token stakers now receive dividends paid out in HIVE and STEEM, you can claim them separately in your profile. Read this post for more detailed explanation.
The site also added a new game:
Since @moonsteem closed their game there was no crash game on the STEEM/HIVE blockchain. Now we again have one. It works like most other crash games, you put your wager and can exit at any time you want, the multiplier crashed at a random point. Max limit is 100x.
KryptoGamers is one of the most established gambling sites on STEEM/HIVE. They joined in January 2019 with only a dice game and since then have added four other games, Blackjack, Video Poker, Casino War and now Crash. They have a dividend distribution system with a Steem-Engine-based token.
