After reading the whitepaper, a couple of questions has been raised:

1) Why smart contracts are so needed to make the games fair and transparent, while standard simple approach exists already for years,
 using hash of server+ client seeds, see for example

https://thebitcoinstrip.com/a-guide-to-provable-fairness-in-online-casinos/

Or for crash games even more simple method with one initial seed and sequence of its hashs of hashs etc. used for the rolls and published in reverse order (e.g. bustabit.com).

Because everyone knows 2 big obvious disadvantages of smart contracts: time and  ether gas consumption ?

2) Why truegame.io plans as high house edge as 14% !!! (see whitepaper) while the most of modern provable fair casinos has no more than 1% (see mentioned bustabit.com and dozens of others) ?

Why the players should choose truegame.io despite these 2 grand disadvantages ?

Keeping the jackpot on the contract makes sense at first glance, but, as was reasonable stated in the white paper, it's better to store the large amounts in cold hardware wallets, so we fall back to dependence from owners.
