There are some unjust bonuses terms and conditions, which may cause issues if a player decides to receive one of CoinRoyale's bonuses.
All deposit bonuses/welcome bonus at any casino will definitely have wagering requirements and additional rules/T&C so that the promo is not cheated by abusers.
I have to admit that there are still some casinos that do not write clearly about these additional rules, but CoinRoyale has clearly listed the terms and conditions for the promo here
https://coinroyale.com/welcome-bonusIf you say some of the terms are unfair, that is your own opinion and does not represent everyone.
I can also say that the terms and conditions for the promo are quite fair considering the bonus is up to 150% of the deposit amount and the most important thing is that all the house edge in any games at CoinRoyale is smaller than the same games at other casinos.
So I hope you do your research first about the games on CoinRoyale, before making irresponsible statements like this.
