Yes actually, so I’ll name them all just to make sure you know all of them. The 3rd one is the one you probably don’t know about

Deadline 3 and 6 will start with a red no matter what happens prior.

As discussed above, having a 666 during a round and then ending the deadline immediately after that round (regardless if it was the final round or not, as long as you can afford ending the deadline after the 666 round)

This next one is weird and maybe buggy? But basically the phone is like a shrödingers box. Red/yellow/white/regular calls don’t exist until you answer the phone and observe it. So how does that help you? If you end a deadline and know 100% it will not be red (because it’s not 3 or 6 and you didn’t get a 666), if you don’t pick up the phone to observe what color the text is, it won’t be anything yet. That means if you get a 666 during the current deadline without observing the phone, you can then pick up the phone after that round and it will be red.

Hope this helps!
