It's a HUGE Scam actually, more details are in their ANN thread
https://bitcointalk.org/index.php?topic=4691540.600It WAS an EOS project, they took ICO money and post "its now ERC20"
As for me, project on EOS preferable than on Eth. Ethereum network is often overloaded, therefore, it can avoid this problem.
Although the idea of the project is not new, but it has a number of unique features over competitors. For example, the fact that Tombola is created on EOS platform.
Tombola now ERC20 based. Not more EOS 
WHAT?!? So everyone who invested in the project thinking it was EOS (that was a selling point your team had) just accepts that ERC20 is the protocol? How is this just decided to use a completely separate blockchain...
How much will the TBH Token price drop due to the Ethereum price tanking the last few weeks? How do you just put a smiley face and not explain anything about this?
They also edited their whitepaper to remove all mentions of EOS, but the whole project was based on EOS originally....
