I didn't realise slow play was a tactic until I copped a face full of abuse from an opponent who accused my of everything short of the JFK assassination. My issue is that, frankly, my internet sucks and given I play on my iPad occasionally I get spectacular app crashes and have to restart.
Sometimes slow play is not a tactic, it's just people dealing with technology or real-world interruptions (like when the Boss says "take the garbage out" and means it).
I have no idea how to cheat or use any tactics other than try to hit the ball in the hole. I assume others are playing the same way.
