Adventure Time Card Wars: 7 Exciting Features, Cards & Gameplay Guide

The Adventure Time Card Wars Game takes its name and premise from “Card Wars,” the fourteenth episode of Adventure Time’s fourth season, which aired July 16, 2012. In the show, Jake teaches Finn a fictional card battle game called Card Wars, and that in-universe game became popular enough with fans that it was turned into real products across two very different formats: mobile apps and a physical tabletop card game.

On mobile, Card Wars first launched as an app developed by Kung Fu Factory and published by Cartoon Network for iOS and Android, built around summoning creatures and casting spells to defeat an opponent. A sequel, Card Wars Kingdom, followed in July 2016 with a similar structure and additional features. Separately, Cryptozoic Entertainment has produced a real-life Adventure Time Card Wars trading card game since 2016, in partnership with Warner Bros. Discovery Global Consumer Products, and continues to release new content for it through Kickstarter campaigns.

Because the name covers both a discontinued mobile game and an active tabletop product line, this guide treats them as related but separate parts of the same franchise rather than a single ongoing game.

Adventure Time Card Wars Gameplay

Across both the mobile and tabletop versions, the underlying structure of Card Wars stays consistent: two players each build a deck around an Adventure Time character, then use Creatures, Spells, and Buildings to defeat their opponent’s forces.

In the original mobile app, players commanded an army of characters, including Husker Knights, Cool Dog the Immortal Maize Walker, and the Pig, placing towers and casting spells to attack the opponent’s side. Playable heroes included Finn, Jake, BMO, Princess Bubblegum, Marceline, and Flame Princess, each carrying a unique hero ability for example, Finn’s ability generated magic points.

The tabletop version, published by Cryptozoic, plays as a 1v1 trading card game where action takes place across four lanes, with Spells, Creatures, and Buildings used to bring down an opponent’s side.

How to Play Adventure Time Card Wars

The specific rules differ slightly between the mobile app and the tabletop card game, but the objective in both is to reduce the opponent’s forces until they’re defeated.

In the mobile version, players selected a deck, then took turns summoning creatures and casting spells during a match, aiming to destroy the opposing side’s creatures and towers. Winning or losing a match determined a player’s standing on an in-game scale that playfully labeled the winner a “Cool Guy” and the loser a “Dweeb” complete with the show’s catchphrase, “Floop the Pig.”

The Cryptozoic tabletop game follows the same “Cool Guy” and “Dweeb” framing. Matches take place across four lanes, and players alternate placing Creatures, Buildings, and Spells to attack across those lanes until one side’s life total is depleted.

Adventure Time Card Wars Cards

Cards in the franchise are built around three main types: Creatures, Spells, and Buildings, echoing the same categories established in the original cartoon episode.

In the mobile games, cards could be collected, leveled up, and fused together to make them stronger, giving players a reason to keep playing beyond a single match. The tabletop version uses physical Creature, Spell, and Building cards organized into themed decks tied to specific Adventure Time characters, such as Finn and Jake.

Cryptozoic has released these cards through standalone Collector’s Packs (such as a Finn vs. Jake pack) as well as bundled sets like the Ultimate Collection, which combines the original six Collector’s Packs’ 12 decks along with additional promos and boosters.

Building Your Card Wars Deck

Deck building works differently depending on the version.

In the mobile Card Wars and Card Wars Kingdom apps, players collected new cards through gameplay and then customized a deck for each opponent, leveling up individual creatures, spells, and towers, or fusing cards together to increase their power.

In the Cryptozoic tabletop game, each Collector’s Pack comes with a pre-built deck tied to a specific character, and these decks are described as compatible with other products in the same Card Wars line, allowing players to combine cards from different packs as their collection grows.

Adventure Time Characters and Card Battles

Both versions of Card Wars are built around Adventure Time’s cast. The original mobile app let players take on the roles of Finn, Jake, BMO, Princess Bubblegum, Marceline, and Flame Princess, among others, while Card Wars Kingdom offered a choice between Finn, Jake, Marceline the Vampire Queen, the Ice King, and Princess Bubblegum, each with distinct magical abilities.

On the tabletop side, Cryptozoic’s Collector’s Packs are similarly built around specific heroes, and later releases expanded the roster to include characters voted on by fans, such as Flame Princess, Fern, Prismo, The Lich, Peppermint Butler, and Magic Man.

Card Wars Kingdom Explained

Card Wars Kingdom is the sequel to the original Card Wars mobile app, released on Google Play and the App Store on July 14, 2016. Unlike the first mobile game, Card Wars Kingdom was available as a free download, supported by in-app purchases and advertising.

The sequel kept much of the original’s structure custom decks and creature collection remained central while adding PvP battles against other players, tournament modes, a “Creature Lab” for leveling up and fusing creatures, and daily or global timed missions offering larger rewards. A stamina (heart) system, familiar from the original game, was also carried over.

The launch of Card Wars Kingdom coincided with the release of a real-life tabletop counterpart, the Card Wars Doubles Tournament game, which launched August 3, 2016.

Adventure Time Card Wars Video Game

Between the original mobile app and Card Wars Kingdom, the franchise has had two distinct video game releases, both published by Cartoon Network.

The original was developed by Kung Fu Factory and described the game as inspired directly by the Adventure Time episode “Card Wars,” built around summoning creatures and casting spells to battle to victory. Card Wars Kingdom followed as a spiritual successor rather than a direct continuation, using package name com.turner.cardwars2 on Android and carrying a content rating of Everyone 10+.

Both games have since been discontinued: Cartoon Network announced via Twitter on December 11, 2019, that Card Wars and Card Wars Kingdom would be shut down. Players who logged in after the announcement received a compensation of 5,000 Gems in-game currency. In-app purchases and certain online features were disabled on December 16, 2019, the games became unavailable for new downloads on December 19, 2019, and official servers for both games were shut down on January 28, 2020.

Adventure Time Card Wars iOS

The original Card Wars app launched on iOS alongside its Android release, developed by Kung Fu Factory and published by Cartoon Network. Card Wars Kingdom followed the same pattern, releasing on the App Store under a slightly different regional title in some markets for example, appearing in Italy as “Card Wars Kingdom: il gioco di carte di Adventure Time.”

Since both mobile games were shut down in stages between December 2019 and January 2020, neither is currently available as a new download from the App Store. Existing installations may still open, but with online and multiplayer features no longer functional, since the official servers have been shut down.

Adventure Time Card Wars and Cryptozoic

Cryptozoic Entertainment is the company behind the physical, tabletop version of Adventure Time Card Wars, distinct from the mobile apps published by Cartoon Network. Cryptozoic’s original tabletop Card Wars game had a release date of March 30, 2016, according to the company’s own product listing, with a relaunch in August 2025.

Cryptozoic has continued to expand the tabletop line through Kickstarter campaigns, including a 10th Anniversary campaign funded in December 2023 and an Adventure Time Card Wars 2025 campaign launched January 28, 2025, run in collaboration with Warner Bros. Discovery Global Consumer Products. That 2025 campaign introduced new standalone Collector’s Packs for characters including Flame Princess, Fern, Prismo, The Lich, Peppermint Butler, and Magic Man, along with new tokens, card abilities, and accessories such as playmats and card sleeves.

Adventure Time Card Wars Game

The tabletop Card Wars game from Cryptozoic is structured as a 1v1 trading card game rather than a traditional board game with a physical board, though it’s commonly searched for and referred to using board-game terminology.

Matches take place across four lanes, with players using Spells, Creatures, and Buildings from their decks to defeat an opponent. Cryptozoic has also released a cooperative expansion, DarkLands, in which two players work together against waves of Creatures and an Overlord equipped with Curses, offering a different mode from the standard 1v1 format.

Adventure Time Card Wars All Cards and Card List

A complete, verified card list for either the mobile games or the Cryptozoic tabletop line isn’t included in the official source material available for this guide, so this section avoids listing specific card names or stats that can’t be confirmed against an official source.

What can be confirmed is that cards are organized around the three established types Creatures, Spells, and Buildings — and that Cryptozoic’s physical releases group cards into themed decks tied to individual Adventure Time characters, such as the Finn vs. Jake Collector’s Pack, with additional cards distributed through booster packs and larger bundles like the Ultimate Collection.

Is Adventure Time Card Wars Still Available?

It depends on which version is meant.

The mobile apps both the original Card Wars and its sequel, Card Wars Kingdom — are no longer available as new downloads and have had their official servers shut down since January 28, 2020, meaning online and multiplayer features no longer function even for players who already have the app installed.

The tabletop card game, by contrast, is actively supported. Cryptozoic Entertainment continues to sell Card Wars products and has run multiple Kickstarter campaigns for new content, including a 2025 campaign backed by thousands of supporters for new Collector’s Packs and accessories.

Adventure Time Card Wars Game Download

For the mobile apps, a Card Wars Game download through official channels is no longer possible. Cartoon Network’s discontinuation of both Card Wars and Card Wars Kingdom means the games were removed from new-download availability on December 19, 2019, and their servers were shut down entirely by January 28, 2020.

For the tabletop card game, Cryptozoic Entertainment’s own website and Kickstarter campaigns are the official channels for purchasing Collector’s Packs, expansions, and accessories. Given the number of third-party sites offering unofficial APK downloads for the discontinued mobile games, sticking to Cryptozoic’s official storefront is the safer approach for anyone looking to buy into the franchise today.

Final Thoughts

The Card Wars Game began as a fictional pastime inside a single Adventure Time episode before becoming two real products: a pair of mobile apps from Cartoon Network, now discontinued, and an ongoing tabletop trading card game from Cryptozoic Entertainment. The mobile games Card Wars and its sequel, Card Wars Kingdom shared a common structure of Creatures, Spells, and Buildings used to defeat an opponent, with Card Wars Kingdom adding PvP and tournament features before both were shut down between late 2019 and early 2020.

The physical card game, meanwhile, has continued well past that point, with Cryptozoic releasing new Collector’s Packs, expansions, and accessories through ongoing Kickstarter campaigns. For anyone exploring the Card Wars name today, the tabletop version is the actively supported way to experience it, while the mobile games remain a documented but no-longer-playable part of the franchise’s history
