If you are an adroid user, you can create a Guest Account on your phone by clicking the ADD GUEST in the settings. Once you are logged in to the guest account, go to playstore and sign in with your google account. Search for HOV in the playstore and click install. It will not download the whole app since you already have it in you main account. You will have then 2M in coins to start playing. Once you are out of coins, go to settings again and click remove guest. Repeat the initial process and you will have another 2M. The only problem is, you cannot connect this to your FB account. You will only play as a guest user.
My game of choice is the Goblins Gold. Most of the time I win in that game, my technique is to play until LVL 12 and if I have enough money I increase the bet to 800k to get the mini jackpot of 64M. It is easy to get this mini jackpot. Everyday I can win in that game up to 300M buy just repeating the process above if I ran out of money.
Once I reached 300M, I go to Ocean's beauty and play 4M bets. Once won the Major Jackpot and won 3.2B.
Hope this help. Enjoy and do not spend money on this game. Its not worth it. Also If you you can add my friend Gerbina Kalerky in FB. We play everyday and can send you 50k coins everyday. I alwasy get 2.5M from my friends
