Oi Frog! is an iPhone game based on the award-winning Oi! book series by Kes Gray and Jim Field. It is a collection of four games designed to develop reading, thinking, and problem-solving skills, perfect for kids aged 3-6.

The first game, Whack a Gopher, is a hand-eye coordination game where children have to whack as many gophers as they can before time runs out to achieve the best score. The second game, Who Sits Where?, is a pairs matching game that develops memory. The third game, Silly Shapes, features six sticker matching games that develop problem-solving skills. And the last game, Lambs Sit on Jams, is a game where children have to stack up to 50 jam jars on top of each other by dragging and dropping them into place. Gravity lets the jam jars fall naturally into place, and the goal is to stack them as high as possible and put the lamb on top of the pile.

Overall, Oi Frog! is a fun and engaging game that is both educational and entertaining for kids. It is a great way to keep kids entertained while also helping them develop important skills.
