Ask to switch over temporarily to watch the stats.
If you have the kind of players who bet all their money at once on roulette and leave, not so good.
If your players chisel away, great!
I am doing very well, I always suffer from winners and not here, and I have some nice loyal slot players.
Good to see the retention too – tells you when each player joined. If you have many older players, likely nice for you.
If you have mostly bonus hunters, not so good.
