One for draw,
One for time left to buy tickets;
Often users get sad that they thought they still had 10 minutes to go and are waiting on that confirmation, to find they can't, or whatever else
be nice to make it crystal clear :D
I personally think that the timer should show the time left up until you can purchase tickets. Then in place of it, a new timer will show up displaying time until the actual drawing. I think this would accomplish both in keeping things simple with the UI, while also letting players know without thinking how much time is left. I think what matters more is players looking at the time and not being able to buy in time for the lotto due to miscommunication over players who see the time and end up having to wait a few more minutes for the actual draw. The first is a difference between potentially winning and losing while the second is just a matter of having some patience.
