i walked into my
local casino, hopped on a machine i know would hit on a “higher” bet amount after lurking watching folks do 50 cent bets (these types of machines rarely pay out decent on low bets so i let folks feed em and then swoop in after they dump 100-200 in 20s betting 50 cents) brought it up to 600 doing 2cent bets from a dollar bet to 5 bucks a bet. hit another 400 and dipped.
yes, slot machines and betting is luck... but if you know how machines usually pay out decent on what bet size and denom you can use it to your advantage after some dummy feeds a machine 200 betting 50 cents and their biggest win is 20 bucks. most times 4 people low betting will feed it and then someone will come and higher bet and eat
