To address the 400% Match bonus, it is automatically funded once a deposit has been received, if something doesn't work out simply ask support for help and they'll be more than happy to help you out.
may I ask, what we get?, when I read on
Promo TOC the user will get USDo, which mean we are only available to play it on the slot game.
PS: Like mentioned earlier in the thread Japanese lettering means "Sandbox". It is done for marketing and brand recognition alongside a small homage to origins of Satoshi Nakamoto, if any of it is true =)
Japan is also popular with Casino, every place I have visited have パチンコ (Pachinko), a place who people can play Casino offline.
We all know Satoshi Nakamoto is uncertain from japan, it's just a name.
It looks better however support has been provided there that will help solve all your problems it would be a shame if they didn't take advantage of it
Even though the admin can actually make it easier by providing a link regarding the rules so users don't need to ask support first.
About the rules or another TOS, I have read about it on
docs.sandboxcasino maybe it's not enough completely, the user still need real support from CS when having the problem.
