The arcade game Frogger is a favorite. To get to the other side, you have to guide the frog across dangerous roads and rivers.
The idea behind Frogger is easy to grasp. Get that frog from point A to point B. But it's hard to put into action.
Use the arrow keys to move your frog. Watch out. Stay away from the moving cars. Jump across the logs in the river to get your frog to its "frog home." There are five of these houses, so you have to do this four more times. After that, you go to the next step.
Each step makes things harder. As you get further into the game, you can expect to see crocodiles, snakes, cars that move faster, and rivers that move quickly. Even a frog with three lives would find this hard.
Have fun and good luck!
