Back before smart phones I always preferred flip phones over “candy bars”, the flip phone helps to protect the delicate screen and buttons while the phone is in your pocket/purse. You don’t really need a case for a flip phone.
Modern smart phones tend to be more delicate than they should be across the board, but in theory, a flip phone puts the more delicate parts in a safer place.
So, as far as I can tell, the primary difference with this version of the game is that it uses question registers?
What does that mean, functionally?
Like how does that affect the software? How would the software run on an actual quantum computer?
