Hi, Tommi. Your charge builds up the longer you play at a table. The greater your charge, the faster you can collect watches. Higher stakes unlock higher charge levels. If you leave a table you will lose some or all of your charge depending on how long you are not actively playing. Ideally, you want your charge to be maxed out at all times but it's not that big of a deal if you lose it. It has nothing to do with your bet or your game investment. I hope this helps. Good luck at the tables!
