In Blast Network, I managed to join a second game while waiting for the first one.
It deducted 400 crowns total.
Steps to reproduce:
- Join a free-for-all game and play to completion
- After the game is over, then click Play Again
- Join another free-for-all game
- While waiting, repeatedly click over the disabled "Play Random Team" button
- Just before you start to load the first match (and the screen starts to fade), the buttons suddenly enable and allow you to click them. Repeatedly clicking will allow you to catch this small window
I actually found this by accident by clicking that part of the screen by chance.
What happened for me is that I joined the waiting area for the first game, then loaded into the second after a brief wait. I couldn't find a way to withdraw from the second game while in the waiting area.
It seems just leaving the "King Krogmo's Coliseum" dialog open while waiting to load into the holding area is sufficient enough to allow you to click the button. You can clearly see all 3 "Play" buttons enabling and the "Withdrawal" button disable just prior to the transition.
Not a big deal since you would only lose 200 crowns each time this (rarely) happens, but it seems like it would be a simple UI fix and add just a bit of polish.
