[hard reject] why my item get hard reject, please help me?

I am submitting a Gambling Game item that is gettinghard reject.Can experts help me make this item get accepted? Thanks in advance <3

I’m not sure about the “logic” as well but the design doesn’t look like it’s good/enough/ready. ( no idea if the coding is okay )

With this state, it looks like a free open source game on Github or Codepen, not a premium item
