My strategy is spinning 50 spins in auto  trying to get the bonus round in Play'n Go.  If it missed then I'll try 20 then 10 spins.  If it still doesn't hit the bonus, I move to another slot trying the same spin strategy.  Most of the time slots in Play'n Go often give a bonus round on that number of spins.

There are times when a slot is generously giving us multiple bonuses round hits in every short span of spin, I often use 10 auto spins per batch to track if I am winning or losing in every batch of spins and also check if it is feeding time for the slots.  It is advisable to get track of the win-lose ratio so that we can stop playing on the slots that are in feeding mode.

since this week's fund is all used up.
