Which are best stake alternatives
I search for good casinos with similar original games
stake is very good and popular gambling site and they provide good original games. So you can go with this.
Because stake is quite VPN friendly. So even if it is restricted for your country, you can change location through VPN and enjoy gambling here. However, if you use a VPN, you must avoid large amount deposits. Because there is no guarantee that there will be no trouble suddenly. On the other hand Rollbit can be a good stake alternative so you can also use it if you face any problem using stake.
I would not suggest to use VPN especially if someone is from the restricted juridictions, because it is simply breaking the ToS.
If someone is from country which is not restricted but unable to access Stake due to ISP block, it is better to use the mirror sites.
Rollbit can be alternative since they provide original games but not as much as Stake.
Shuffle, the one in my signature can be alternative too and there are original games as well although not as much as Stake provide but the games are similar.
