Today's Free App of the Day is Civiballs
Originally $0.99

This is apparently a cut-the-rope style game. From the product page: Product Description Set off on a puzzle adventure through three of the most famous civilizations in history, the Roman, the Vikings and the Incans. You play as a young scientist and his pet monkey, who are travelling back through time to rescue ancient artifacts (or in the monkey's case, steal ancient jewels.) You'll have to cut chains or ropes to drop coloured balls into matching pots. It may sound easy, but the taxing physics puzzles involve bizarre objects like crossbows, catapults, fountains and volcanoes. It certainly makes for addictive gameplay. Watch out-things get tricky and you'll need to use your head, and some quick reactions to solve later levels - especially if you want those bonus diamonds! Easy to pick up and play, with colorful visuals and classic puzzle gameplay, Civiballs is a brain teasing adventure not to be missed. The issue is the permissions. If you like this kind of game, the reviewers recommend playing without WiFi connected..

2 of 10 reviews are four stars and above.

So we have a bonus pick: Pic Collage.

This is a nice app for making collages of your pics. I wanted to make a collage to audition fabric choices for a quilt. It is very simple to use--you can choose layouts from one that looks like a pile of pics (and you can rearrange the pictures) to very structured choices. The choices you are given are based on the number of pics you have chosen. You can save your pics to your device, or you can post them to Facebook or Twitter or the app's site. You can pull pics from FB if you want to give it access, but you don't have to give access. Some of the one star reviews referenced permissions, so be sure to check those if you are concerned. 324 of 365 reviews are four stars and above.

These apps are compatible with the original Fire and with my Fire HDXs. To tell if an app works for your Fire HD or other Android device registered to your Amazon account, click on the above link and look on the right side of the web page. Amazon will tell you if it will work with your registered device.

Have fun!
