Mate, there is no strategy that works in any slots, we just have to spin and expect that they will pay, if you are looking for a strategy to win, there isn't any.
If you really are making money in Keno I would suggest you stick to it, because slots is a trap, you will always end up losing money in slots, at least in Keno you will find some strategies on YT which you can follow and try and make money, don't play slots it is absolutely meant for entertainment, expecting it to pay is pointless
