After the game loads, the first screen reminds players to JUMP by pressing the left mouse button. To jump higher, hold the left button down longer. The object is to collect as many coins as you can while answering subtraction facts. To begin the action, click anywhere on the opening screen.
The explorer will run forward. The number of feet he has traveled is shown in the upper right corner of the screen. Below it is the number of coins collected.
Some of the coins are magic and won't let you travel farther until you have correctly answered a subtraction problem! Click on the correct answer to continue.
As you get further into the cave, you will run into more hazards. To jump over them, hold down on the mouse button longer to jump higher.
When your explorer misses a jump, the game ends and give you an option of trying again. The screen displays the distance you traveled, the number of coins you collected, and your total score.
