Far as I know, casinos do have bonus and promos that have their own rules. Like for example you can only wager in sportbet section and the bets you placed in casino won't count toward the progress, or that to claim the bonus, certain games are not counted. I'll try to reach Kirito with the image you provided, see if he can point us down to the specific bonus and whether indeed there is a specific rule or not.
The bonus I claimed is on dice and the bonus unlock wager was count when I played in dice. and yes I played only dice. It is written in the ToS if you read it.
