3D Froggy is a fantastic game of logic in which you have to get all the frogs except one to jump into the water.
3D Froggy uses the classic solitaire gaming system, where the frogs move by jumping over eachother. When a frog is jumped over, it will then jump into the water. The more you jump over the more go into the water (they are all numbered). Thus, you must continue like this until only one remains.
3D Froggy has many levels that get more complicated as you advance. Simple and free.
