Any thoughts on this BTG grinder, as well as other grinder games, can I just use bonus funds to grind it..... if its not in restricted games of a bonus is it ok to grind it collecting the hearts or bars or whatever collectable..... and if I grind towards the goal of reach 40 hearts/bars, when reaching 39, then switch to another game , finish wagering on that other game or bust out the bonus..... and then return to Lil dev (or other game that you have collected 39) and then play the spins to get the enhanced bonus...... by getting the 40th item.. or just stay on the game for entire time including for the enhanced bonus...
we all know these grinder games usually cost a lot of money during the collecting stage and the enhanced bonus is likely not going to pay back enough to cover the investment... but if we use bonus funds then it would at least cut the cost of the entire journey.
