Are wager filling conditions available for all games?
Yes, as you can read on the full details of the promo point #4
What if the wager is not achieved by the end of the event?
IMO your winning and bonus will be forfeited. If you are losing at the end of the promotion, means that you will have nothing on your balance.
Anyway 1 month is more than enough to wager 100x of your bonus if you keep playing regularly even with small bets.
Anyone take the bonus should notice about the ending time, so they should try to wager the bonus as fast as possible before the deadline.
