Club Penguin Island

The Clothing Customizer, referred to as The Designer in loading screens, is a feature in Club Penguin Island that players can use to create clothing, utilizing blueprints as bases, and optionally, fabrics and/or decals as well for design. All players can use the Customizer, although only members can wear the resulting clothing. Members have the ability to sell their clothing and buy clothing submitted by other players. Each day, there is a different type of catalog, with a theme. The theme of the catalog determines which blueprints, fabrics, and decals can be used. The theme resets at midnight in Penguin Standard Time. (PST)

Adventures, also known as quests, and prefixed with ep. (short for episode) are activities in Club Penguin Island that players may partake in, and are received by talking to specific quest characters. Adventures involve players traveling around the island, completing tasks, and solving problems. Completing adventures yields coins and XP, and often various other rewards as well, such as a unique item or blueprints. Members are able to take part in every adventure. However, non-members are limited to taking part in one adventure from each character.

Daily Challenges are activities in Club Penguin Island that players may partake in daily. Each challenge requires players to perform certain actions in order to complete, and each yields a reward in coins and XP, although some community challenges do not yield XP. There are a set of four challenges per day, and these challenges change every midnight in PST but are always in the same set of four. They can be accessed through the Island Live Phone, which displays a tab of the day's challenges. Completing challenges is one of the ways players can gain levels.

Scattered throughout the island are collectible items that can be exchanged for coins at the Beacon Boardwalk. Each collectible has a certain coin exchange rate, location where they are available, amount available per area, and respawn time after collecting.

Each player is provided with an igloo for a home which both members and non-members are able to customize. Members have the ability to choose from many variants of igloos as well as purchase items from a full catalog of furniture, landscaping, terrain, interactives, and more. Non-members are able to purchase two types of igloos and non-member items from the catalog. Items can be bought with virtual coins that are earned by playing mini-games, collecting coins throughout the zones, and trading in collectibles at the exchange. Like its predecessor, Club Penguin, anyone can access a players igloo on Club Penguin Island by clicking the igloo icon on their profile, provided the player has selected to make their igloo public.

Gear is a type of item that members can use to perform various actions. Gear that is obtained through leveling-up or adventures is portable and can be used anywhere on the island. There is also gear that can be found in certain locations and can be used even if the player has yet to obtain it. Non-members can only use the jackhammer gear.

Several events were held on Club Penguin Island. In most cases, one or more free items were made available for everyone to obtain. Some events came with quests that all players were able to participate in. One example of this was the Halloween party. Like its predecessor, the game also hosted some sponsored events.

Party Supplies are consumable items that can be bought at shops by members, and can be used, each with varying effects. Party Supplies include items such as fireworks, edible items, and party games.

Club Penguin Island contains a variety of games, eight of which are available for all players. Most of these games reward the players with coins and XP upon completion. Both members and non-members are able to purchase and use the party games Marble Hunt, Ink or Swim, and Fossil Four. There are also games that are built-in to the Club Penguin Island zones. Team Dance Battle is a multiplayer memorization game that everyone is able to play with the maximum limit of players in each round being a total of twenty, and at the minimum, one player in each team. Tube racing is a multiplayer racing game that is played by everyone on the top of Mt. Blizzard every couple of minutes. Other games for everyone include the Sea Caves Race Course, the Crate Co. Target Game and Tilt-o-Tube, which involves players trying to knock their opponents off a floating platform.

Island Live is a feature added in the 1.8 update of the game. It's the successor of the CPI Phone that was added in the 1.2 update. It can be accessed by clicking on a Phone icon. It shows information about live events taking place on Club Penguin Island, displays Daily Challenges and contains a variety of apps, like a Friends menu, Island News, and Settings.

Club Penguin Island's revenue was raised predominantly through paid subscriptions, cheaper than its predecessor, of a one-week, one-month, three-month, six-month or twelve-month paid membership, although free access of the game is available. Membership allows players' access to a range of additional features. This includes designing all clothing, wearing all clothing, buying Party Supplies, playing all adventures, completing all Daily Challenges, the ability to use all gear and more. Penguins with a paid membership are called "members", whereas players who do not have a membership are referred to as "non-members".

Although members gain additional features, players without a membership can obtain all event items whether they're a member or not, obtain wearable event shirts, customize certain items in the Clothing Customizer, play the first adventure of every quest giving character, use Party Supplies given to them by members, customize an igloo (of which anyone is able to visit) with any quantity from a selection of non-member igloo items, play all mini-games, use the jackhammer gear, buy and play party games, join tube races, waddle around anywhere on the island, chat with other players, reach the maximum Penguin Level, and take part in non-member Daily Challenges. After the 1.10.1 update, non-members who signed up during the pre-registration period are now able to wear the beta hat, and if they connected their Club Penguin usernames for use in Club Penguin Island, their alumni jacket too.

All players automatically received a free, unlimited membership on November 5, 2018, which would carry over to Offline Mode. Refunds were processed for memberships extending beyond November 6, 2018.[6]

Offline Mode was added to Club Penguin Island in the game's final update, and it was activated on December 21, 2018. It allowed players to login to a limited version of the game, which stored your penguin on your device. You cannot see or interact with any other penguins in the game.[17]

A new feature called Debug Mode was also added, which is a tool that Club Penguin Island's developers used to test the game.[18] It allows players to teleport to different locations in the game, add a custom number of coins to their account, and import/export their player data - among other tweaks. A network menu appeared in Debug Mode on December 25, 2018.[19] The network menu allows players to create their own private server using SmartFoxServer (similarly to private servers from the original Club Penguin), however there is no documentation on how to do so. A content submenu also appeared on March 28, 2019 - which allows players to customize the game.
