Genuinely curious how many people sit and read through the paytable and rules before spinning. I never used to bother but got caught out on a slot where I didn't realise the bonus had a specific mechanic I completely missed. Now I at least skim it.
I always at least check the bonus mechanic before buying or playing long. Had a slot once where I didn't realise wilds didn't pay in the base game and wasted a whole session misreading hits.
