This game required to download .exe file and i am afraid to install this file on laptop because there is some possible to get hacked, i have question is that game has safe to play from this software or any kind of flash version available to play online from web browser.
Never install an .exe, which is coming from a trusted source. Better try web based games.
Yeah these days most games are browser based. Even if you use a virus scanner it might not detect the virus because it could be 0 day.
I can understand your caution but let me assure you after playing this game for several years that Teppy is not laying in wait to hack your bitcoin wallets. It's a casino, and an absolutely addictive and fun environment. You will hand over your btc all on your own. Or maybe you'll get a huge jackpot, withdraw it all, and never be heard from again. I've seen both happen many times.
