Here's an interesting & funny question to try and get some discussion going - does anyone here play games on their phone or tablet whilst taking a dump and if so what games do you play? Do you even consider playing games whist dumping or do you just read a book? Or, do you simply make grunting noises and / or funny faces, wipe then leave as quickly as possible?
I find simple games such as angry birds are best for such short 5 to 15 minute daily events. The number of levels you can get through depends on the difficulty of the dump of course
but I think long games like RPG's are too long.
