I had two sessions of slots last week using bonus balance ($5 Touchdown and Luck o' the Irish) where winnings were not crediting. Of course you spin quickly, so it was about halfway through, when I hit big spins, that I started to notice this. Thought it was the first game so tried the second to find the same problem. No idea how much they deprived me of. Three emails yielded a run-a-round. I gave the the games, the date, and a window of time. All they had to do was track the plays. Instead they told me I had to give them exact times, balances before and after spin, etc. IMPOSSIBLE to do.NONSENSE!!! I expected better than this. Now I wonder if there is a mechanism that keeps players from making their play through requirements?
