Solis — On-chain Collectible Card Game: Introduction & Game Design

People to this day collect and play collectible card games —like Hearthstone, Yu-Gi-Oh!, etc. — despite today’s technological advances of modern gaming.

The appeal of CCGs can be taken to the next level through crypto.

Using the blockchain as a medium and NFTs as building blocks serve the perfect conditions for a CCG — like Solis.

Solis is a turn-based CCG deployed on Fantom where players can battle against one another, consequently gaining rewards and improving their NFT cards’ stats.

Solis aims to:

• Allow players to trade P2P without being locked in the game (buy and sell cards in open markets).
• Provide complete ownership of game assets (the cards are yours and only yours!).
• Deliver a variable card design (improvable or destructible over time).

Solis Cards

Solis cards are playable NFTs that come in 4 different types: Sapienoids, Malisoids, Spells and Enchantments.

Sapienoids

There are 3 classes of Sapienoids: Aquasapiens, Aurasapiens and Terrasapiens. They are the character classes of the game. Each Sapienoid has a distinct appearance and a set of stats (attack, defense, accuracy, evasion). Some Sapienoids are good at performing attacks, while others are better at defense. However, there will be similarities in stats between the original Sapienoids. Furthermore, due to the variable design of the cards, they will evolve differently. This aspect of the game will be later discussed in greater detail.

Malisoids

Malisoids support Sapienoids while not having battle stats. Instead, they buff the stats of a Sapienoid of the same class (Aqua/Aura/Terra).

Spells

Spells perform active or passive abilities that can affect the gameplay, the player’s cards or the opponent’s. They are either earned through grinding or can be purchased from the marketplace. A spell card is consumable and can only be cast a limited amount of times.

Enchantments

Enchantment cards are used to improve cards stats. They will be issued on a regular basis in Solis marketplace; more on that in a separate article.

Game Requirements

In order to start a match, each player is required to:

• Have a minimum of three cards.
• Have a sufficient amount of Mtoken to be able to pick one of the preset bets of the game.

Game Design

After meeting the aforementioned requirements, the game will start match-making with another idle player of the same bet. The two players will then enter the game board; the game will randomly pick a player to play first.

Game Board

The game board consists of 3 main card slots for each player; the card formation is one card ahead and two side-by-side cards behind.

There are 2 additional slots in the game board for passive spells while active spells will be cast and destroyed right away.

A Malisoid card will be stacked on a Sapienoind instead of taking a card slot.

Hence, there are a total of 5 slots.

There are 4 phases in the game: Cards Setup, Endowment, Attack Strategy, Battle.

Phase 1: Cards Setup

The player should place their first card in the desired slot; the card will be revealed on the game board for both players. It will then be the opponent’s turn to play a card and so on until the game board is full.

Phase 2: Endowment

Afterwards, each player will have a total of 5 points, which should be wisely allocated across the played cards — for instance, increasing a card’s attack by 3 points and increasing another card’s evasion by 2 points. The endowment will only affect a particular stat of a card the player chooses.

Phase 3: Attack Strategy

Playing the cards is position sensitive; if the left-positioned card on the game board is going to attack the right-positioned card of the opponent, the accuracy of the attack will be negatively affected. Each player should consider their cards’ stats and the opponent’s to decide their playing strategy.

The player who didn’t make the first move in the Cards Setup Phase will the one to start this phase. The player will start by choosing a rival card for one of their cards. The two players will take turns forming their attack strategies. The strategy moves will be visible for both players.

Phase 4: Battle

The game will then execute the strategies of both sides and calculate the damage for each card. As a result, cards will either be deteriorated or destroyed. If all the cards of one player are destroyed, the other player wins. If not, a new round will unfold.

Game Rounds

The game will go at rounds until one player eliminates all the opponent’s cards. The winning player will be rewarded the Mtoken bet of the other player.

Rules

• Each player will be given a timeout of 5 minutes in every turn; otherwise, the turn will be skipped to the other player.
• In the first round’s Card Setup phase, if the player misses a turn while their card slots are vacant, a card slot will be disabled as a penalty.
• If the player has no vacant slots, skipping a turn will be an option.
• In the case of new rounds, both players will get the chance to only play spell cards.
• A player can only play another passive spell if one of the used spells gets destroyed.

Roadmap

Sapienoids NFTs are ready for sale, which will be announced soon. The first version of the game will be available in the upcoming weeks for cards holders. The next step is to gather a community around the game to decide and shape the future of Solis.
