Click on the frog to begin. This will not
do anything other than give the applet focus so that you can start
using the arrow keys.
Your goal is to get the frog to his lily pad.
The frog may only jump to a log if it has an
expression that is equivalent to the expression on the lily pad.
If the frog lands on a log with an expression
that is not equivalent to the one on the lily pad, then you will be
sent back to the bottom and lose a level and the snake gets his
lunch.
If the frog falls in the water or is taken to the
snake's log, then the snake gets his lunch and you will be sent back
to the bottom. A level will not be lost.
Use the four arrow keys (Left, Right, Up, and
Down) to help navigate to the lily pad.
There are twenty levels.
Since at the beginning of each try, time is not
an issue, it will help to write the expression on a piece of paper.
