While playing the Studio City slot game, I walked away from my computer. When I returned, I saw that I was on bonus round (stage 3?). Before I had a chance to click on any of the cards, I clicked on a few links in my Facebook feed, hoping to get some 101 and 201 chip rewards that hadn't been claimed by others. One of the links was bad (sometimes people accidentally post links to the game, which will cause your other game to throw a "Sorry, something went wrong" message, and tell you to reload the game). When the game reloaded and I went back in Studio City, I got the message saying my bonus round was interrupted, but that I had won 10 free spins. What? I hadn't clicked on any cards, so how do they determine that I won 10 free spins? I haven't tried to recreate this yet, but is this proof that your bonus is predetermined?
