I've tried 2 browsers now--Chrome and Duck duck go --and in neither does my keyboard pop up when I click on a square. Am I doing something wrong or is this a common problem on phones?

Edit: I see spell check changed Subeku to Subaru. ha!

I have this issue, too. I assume that it's just not meant to be played on mobile? Even though it seems like other games are able to be.

that stinks. I really wanted to earn that achievement book!

My phone keeps signing me out on Subeta
