Solid tips you've got there. I would add to your list to be patient, waiting for the moment to play your bank.
I've played a few rounds of online poker myself, and while it's thrilling, sometimes I find it too taxing mentally. I'm more inclined towards slots because it's quick and relies more on luck than strategy, which is a fun change of pace.
For slots, I am playing only on Joker123. They have there my favorite Mania Respin slot, from where I snagged 300$ by using the free spins I won. Download joker123 and try your luck!
