These style of megaways games with variable number of bonus spins and increasing multiplier are usually random on every spin, so you are better off gambling for more spins / multiplier, assuming you’re okay with the risk of losing. Also they would not be allowed in accordance with GC rules to work in a way such that gambling with a risk of loss made no difference to the outcome, since it would clearly be misleading the customer. You will usually find a bit of small print somewhere in the info for these games telling you the “best strategy” is to always gamble.
What can happen is that the maximum gamble you can achieve before losing is pre determined at the point of landing or buying the bonus. I’m pretty sure Extra Chilli works that way.
