How to play

Same video, two thumbnails. Each round shows one video on Vidlo, a made-up app, with two thumbnail versions drawn side by side.
Pick the winner. Tap the one that got more clicks, or more views after a week when the question says so. Keys 1 and 2 work too.
Beat the clock. 16 seconds for the first round, down to 9 for the last. A wrong pick or a timeout costs one of 3 lives.
Score. 100 per right pick, up to +50 for speed and +10 for each right answer in a row before it (up to +50).

Quick tips

Look for one clear subject. The winner usually has one thing to look at: a face, a tent, a shoe. Clutter loses.
Squint at it. Thumbnails are seen the size of a stamp. If you can't read it squinting, neither can a scroller.
Check the corner. The video-length badge sits bottom right. Words hidden under it don't count.
Follow the eyes. A face looking at the subject sends viewers there. Looking away sends them out of the frame.
Read the question. Some rounds ask about views after a week: a thumbnail that tricks people into clicking loses there.
