Warning – time sinkhole ahead. A really fun and challenging one though.
From Google Research comes Semantris.
It’s a pair of word games driven by machine learning.
You have a choice of playing for speed or for accuracy.
I prefer to play for accuracy so head to the Blocks option.
This is where the machine learning kicks in.
The concept here is to stop the bricks from reaching the top of the screen by trying to describe one of the words in a box.
It’s easy to play and describing how to play is actually pretty easy. But, it’s not easy to beat and eventually, I lose. But, in a good way. Trying to figure out what’s going on is fascinating to me.
The other game is the Arcade and you’re playing for speed there. It’s fun but I’m drawn back to the Blocks just because I like to feel like I’m watching my computer think.
Give it a try and let me know what you think!
