Curation is King

One of the strengths of the Internet is that it enables anyone to curate information. Most major platforms do so in some form, and it normally follows the process of someone posting content, followed by a ranking through upvotes and likes. The results define if and how content will be displayed in feeds and lists.

We want this to be reflected in the first application we build on the MarbleCards platform.

The objective of this application – called The Arena – is to combine the curation mechanic above with what makes unique, namely the collectability and itemization of the Internet itself.

Introducing The Arena

Rise in the ranks and earn by playing your favorite Marble cards against others — around any theme you can think of. Here is a first sneak peek.

In the Arena, players compete with their cards in various “Leagues”. A league is a ranked list of Marble cards around a certain theme, similar to a subreddit. Every league has a unique #name, and is represented by an NFT owned by a player. Owning a league will generate passive income for the owner.

Each card in a league is ranked based on the Battle win ratio of that card. Anyone can submit a card to a league, as long as the card meets that leagues requirements such as minimum level, specific collection etc. The cost to add a card range from free to costly depending on what rules the league owner has set.

Once a card is added, it starts to battle other cards. A Battle is two opposing cards fighting for votes from other players. For voters, how often you vote on winners impact what rewards you get, such as XP, Marblecoin and ETH.

How To Play

Players get rewarded in the game by performing well in certain areas. It’s possible to both get rewards that are dependent on being active or that does not require attention from the players once set up. Rewards are related to owning cards in Leagues and Voting well.

Card Owner

As the owner of a card in a league, you get part of the rewards pool that was allocated to that league. The amount that you get is based on the placement of your card in the league, and the attributes the card has such as Origin, Level and Gold.


Players that vote in battles get rewarded based on how good they are at voting on the winning cards. Best voters get the highest rewards.

League owner

As the owner of a League you get part of the rewards allocated to that league. The amount is dependent on the popularity of the league, and something called the Fuse Score that will be based on the quality of the card that the list owner has, more info will be posted later on this.

Ranking of Leagues

How much rewards a certain league will be given depends on its Rank towards other leagues. Rank will be based on a popularity algorithm that takes several different aspects into consideration. For instance the activity in a League in terms of number of battles, number of new cards, number of visits, amount of outbound traffic etc. Please note that the distribution of rewards might be different when we launch, numbers should be seen as what we currently see as a good solution but might change. Rewards distribution used at launch will be posted before launch.


This is the first preview of the MarbleCards Arena, development has started. The game will be launched in steps and there is currently no launch dates decided. To get the latest news, join competitions and a future chance to get some of the early Leagues please .
