The most difficult game to play is always the last game on the check list, most people are only scared to go far with the green, potentially have a good chance to make profits already and blow it up while looking out for a much bigger profits. I will be good to cash out if i have made enough profits from my slip, being contended some times can save from losing more parley.
Sometimes people add the last bet in the bet list because they want the bet to be high. If you notice when betting when you add extra games the odds kept on multiplying more than when you have only few games there. This is more likely the reason why the last game are being added. Even if there might be other games in it.
My perception about cashing out is that, i see it as an opportunity for us to collect our win, irrespective of how small it was presented. But sometimes we are being blinded by greed with the mindset that, what will be, will be. I have lost so much by acting greedy when I had opportunity to cash out, even if the ticket is running at loss and you're provided a small sum to cash out, do so because that money could be used to make another ticket, and who knows maybe that might be your lucky game. Though sometimes the choice of cashing out becomes really different when the last game seem to be a walkover, but that could be the game that'll change the status of your ticket to lost.
