Whatever you guys want to call, its fine. Just stick with your own because everyone has its own preferences. I personally prefer to call it 4823x but that is just my own preference.
My logic would be spending $10 bonus buy on $0.1 base bet is literally
similar to spin $0.1 base bet 100 times trying to get the bonus feature naturally. You can try to get the bonus feature by spinning it but sometimes it might takes over 200+ bets to get it
So the question, will you consider your 4823x multiplier to be around 10x instead if you spend around 400+ bets ( $40+) trying to hit the bonus round? I personally will still consider it to be 4823x though

Meanwhile we have another contests up and running

20 places paid for the points race and there is twist to the Ultimate Slot Battle, 3 player that hit closest to 500x would win . $0.2 minimum bet for both of these contests, goodluck everyone !
