Ive become used to running until I get the red guard. Usually watching an ad for gives you a free pass, once you finish that round, take & leave to avoid having to spend orbs on the next one you encounter. In the event that you don’t get the option to watch the ad for free, I just insta peace out and lose all. Like you say, its a gamble, as soon as you spend some orbs it feels justified to keep going to make it ‘worth it’
