There's now a "tick" audio alert to accompany the hourglass that indicates you are timing out.
This was added to help people who may have been away from their computer when the "gong" sound indicated that the game was starting. If someone doesn't have the browser open to World of Card Games on their desktop when the game starts, they may be timing out while they are doing something else. For example, their browser might be minimized, or they have another browser tab open for reading the news, etc. This new little audio reminder will help to solve that problem.
Thanks to the player who suggested adding this!
