Last time in Tokyo I played quite well. Call it beginners luck I guess. This time I noticed quite a few more machines used the card method instead of balls and a tray. I hit a fever once today and did not open the drop tray for the balls to continue to drop to collect for the card... Did I screw up and lose all of the yen I earned during the fever? I noticed the top tray was full of balls after the fever and I released them. It did not seem like it was as much as I hit however.

Also, is it normal to not be able to cash out money that has not been played through yet, I took a card to the counter I put 90000 yen on previously but when I tried to change it back they told me it was for "play only"
