Pretty Good

Works really well, only hard part is finding where you are in the loop. I found it easy to see how many wins I have. As you can win without receiving a chest, if for example you have full slots. Then check the last giant or magical I got. Then I know I am somewhere within that set of chests. Then I track the pattern of how I receive chests and j found where I was.
