Do you remember playing games made by Ravensburger? I'm an 80's baby and we had a bunch of games with that blue triangle in the bottom corner growing up. Well now Ravensburger has an app that I can't get enough of! It's called Take it Easy. I'm pretty sure it's meant for children, but I can't stop playing it!
Each game is a puzzle. You are given puzzle pieces one at a time and you try to fit them together to make points. It really requires some thinking and planning.
In the first game you cannot rotate pieces or move them after they have been placed so it's REALLY challenging. You can see a video of the app right HERE. It's an app that's great for students of all ages....and maybe for grown-ups too. It's $1.99 and worth every penny.
