mobile-friendly puzzles

Why is this post so badly formatted you may ask?
Well it's because I am dictating into a mobile phone.

a lot of us are busy and on the go these days and don't have time to sit at the computer and solve puzzles but we'd still love to have some fun.
I propose for the monthly topic challenge mobile friendly puzzles. These are puzzles which can easily be solved on your mobile phone using common knowledge or perhaps looking up a few things, but not poring over complicated charts or graphs, using Excel, filling out drawings, or requiring extensive markup or time writing out a beautifully formatted entry.

Creating a good mobile-friendly puzzle is a true challenge for a Puzzle Master for they must create a puzzle that is simple enough to be viewed and solved on a mobile device and yet elegant, interesting, and unique. It should be answerable in a few lines of text or perhaps by uploading a simple screenshot with minimal markup.

There are plenty of examples on this site; here's one at random:
It's a... Ohh... puzzle (BpFp)


In the spirit of this being a Challenge, entries should be innovative and new in some way, to the op's knowledge. For example:

-Something that looks like an affix-riddle or What is a Word, but is actually something else entirely, or takes a new or unexpected twist.

-A puzzle with a visual component leveraging a never seen before mechanism.
