Honestly, if I myself play in a slot casino with a small bankroll, it is not satisfying, it will finish the game faster because the capital has run out, but it depends on the reels you play.
But there is no best way in gambling is with thin capital then this will not cause badness because you have limited it.
I also still have a small capital but almost the bets that are played are sports bets which are certainly fun especially watching together with friends or other relatives on the other hand in my opinion sports betting odds can be maximized depending on your ability to analyze the team but so far the odds above 4.00 are more than enough for me.
If we are lucky, even with only a small bankroll we can get multiple wins when playing slots. in fact, it's not uncommon for me to win even though I'm just playing for fun with a small bankroll. although as you said, playing slots with a small bankroll is less satisfying. well, what's less satisfying is that the game session ends quickly. Moreover, the game we are playing is not giving a good shot. however, therefore, you are limited to not experiencing worse defeats. but the worst, when the emotion of anger is involved, and making deposits again and again.
Like you, I also prefer sports betting. Apart from providing an adrenaline sensation, sports betting can also provide big wins even with a small bankroll. It's just that, that means we choose the multi bet betting option. Patience is involved here, both when choosing a team, researching and analyzing and waiting for each match to start. If the results match estimates or predictions, that's very pleasing. however I personally prefer single bets with the various odds options available. the most ideal and attractive odds, that is the choice in betting. however, I have to be sure first to choose a bet that has really been selected first. yeah, that's usually what I do.
