'Play A Match' area

Hi
In this area there are 8 potential opponents. Can you advise me how often these refresh please?
is it individually per stadium, or at a set time?
Do they only refresh if all opponents have been cleared?

so some info on this would be great please.

These are training matches ...
As you clear space, a new opponent is delivered every 4 hours.

They use a small amount of energy but award training points to your players.

Play 6 a day
Hi Taff,
thanks for your response. 4 hours, thanks thats a hard stat that I can get hold of!
do you know about the training points, it doesn't seem to be a point a match and I wonder how this is calculated and assume that it is partially reliant on the training speed

Impossible to say given its based on training speed, energy and training ground level, but aim at 10 TPs per player per day and you will do well.
thanks Taff, that all makes sense. It's a shame but no surprise that none of the developers managed to provide a response. I don't think the 4 hour refresh rate is correct because all the slots aren't full in the morning.

8 slots, start empty, 32 hours to fill.
Sometimes if you play a game, miraculously the empties fill, a refresh bug me thinks.
