Jet Pack Adventure was a Club Penguin mini-game that could be accessed from the Beacon. If the player reached to the end of Level 5, they would land in the Mine. If a player lost before the end of the game, they would land in the room they were flying above before they lost, which was unknown when you were flying.
Players traveled from location to location using a jet pack, collecting coins along the way. If the player ran out of jet packs, a short cutscene showed the penguin falling from the sky and safely landing on the ground (in the Mine levels, the player did not reach the floor). Extra fuel could be collected, but you had to watch out for anvils and coffee bags. Another occasional obstacle would come, such as a shark.
You could send a postcard to a friend to go on a Jet Pack Adventure (which sent you to the Beacon). On July 26, 2010, the game was changed so only the first level of Jet Pack Adventure was playable for non-Members. Only members could play the entire game due to the addition of the new stamps that were released that day. Another change was that the home-screen was updated. As of September 13, Green Puffles could assist during flights. The Green Puffles would fly around your screen collecting coins and fuel cans, it was impossible to get the 0 coins stamp or bonus by bringing your Green Puffle with you.
If you complete the game without collecting any coins, you get 1000 in the end. You can still collect fuel, but at the end of a level you will have to waste all your fuel until it runs out and you fall on the landing base. You must keep doing it until Level 5 and a picture will appear saying that you are a highly skilled pilot. You will also get the Ace Pilot stamp.
At the end of Level 1, if you continue past the launchpad, over the Coffee Shop and down it is side you'll find an extra fuel can and a "ten-coin" coin.
The 1-up locations are:
Level 1: There are no 1-ups in this level.
Level 2: Go straight up at the beginning of the level and dodge the windmills. Travel at the top of the level until you find it.
Level 3: When you get to the top of the mountain near the end of the level, go left to find the 1-up in a windmill.
Level 4: At the end of the level, when you see the "Land here" sign continue going down to find the 1-up.
Level 5: Stay on the right of the pit until you see a warning sign (triangle with an exclamation mark on). Go right and then up to find the 1-up.
During the Aqua color release, it had a glitch that it blinked into a white screen, then you cannot start the game or instructions, only exit it. That glitch was fixed.
Sometimes when you started the game, the starting screen would still be in the background.
If a shark in Level 3 hit you while you were barely floating above the water, you could glitch under the level and constantly get hit until the point where it was impossible to get out.
