Mahjong solitaire for preschoolers - Easy and fun way to learn mahjong!
if anything on the chrome game store has "duckie deck" in the thumbnail or title, it's very likely going to be a very bad app, parading as an educational game for kids. It just takes you to the game on an ad-congested website. It's very obvious that these games aren't for education, but for ad revenue. Don't use this rubbish. also, it looks like they bought into the solitaire and mahjong cloning.
