I would suggest you get rid of that domain and redirect to a nice brandable one, preferably with .com
Your domain doesn’t really help seo wise and I doubt you are hoping to actually rank for ”online poker”, which is probably among the most saturated, competitive keywords to go for. on-line-poker.net is also not easy to remember and isn’t catchy, so there’s really no reason to keep making a nice quality site on a domain like that.
