Today’s FREE app from the Amazon Appstore is Cross Fingers.
Cross Fingers is a unique game which challenges you to combine solid pieces in a gigantic tangram puzzle. You will need to exercise your brain, imagination and your reflexes and dexterity to complete all 120 levels! To complete a puzzle, combine the bright pieces of wood so they fill the dark background shape. But watch out: the red pieces snap back to their initial positions, so you may have to hold them in place. Fingers crossed!
