Ribbit is a fun little game that teaches kids to recognize shapes. Rectangles, triangles and circles need to be dragged onto the board; gradually revealing the colorful picture underneath.
Applause welcomes a job well done if the complete board is cleared and a slide show of attractive animal pictures forms further reward.
This Mac OS X app is completely free. Of course it's more fun to play on an iPhone or iPad where Ribbit is available as well.
Up to six family members will be able to use this app with Family Sharing enabled.
