Tsubasa

Tsubasa onchain game running on Starknet Appchain.

About

Tsubasa is a football game based on the popular manga series of the same name. It's a simulation based on the rules of the game, but with a twist: the players are able to use superhuman techniques, such as the Tiger Shot, to make the game more exciting.

The game leverages the Dojo Engine, a provable game engine and toolchain for building onchain games and autonomous worlds with Cairo.

It can run on the public Starknet, or on a Starknet Appchain using Madara.

How to play

Rules

Decks

• Each player has a deck that he prepared before the game
• Each deck is composed of 8 cards
• There are 24 cards available in the game (for now).

Game

1. A game is composed of multiple rounds
2. The first player to win 2 rounds wins the game
3. To win a round a player has to score a goal
4. Each player can place 4 cards at most on the field
5. When you place a card on the board it'll wait on side until your next turn to enter the field
6. To place a card you'll need to spend the amount of energy specified on it
7. The energy level is reset and increased at each turn
8. You can place multiple cards on the board during 1 turn
9. Each card has 2 statistics dribble/defense
10. If you place your card in its real role it will have +1 in dribble and in defense
11. The defense is the ability to counter a dribble. If a card A (6 dribble, 3 defense) attacks a card B (2 dribble, 4 defense). The card A will dribble B for sure because 6 >= 4 and will go out of the game. A will stay in the game because 3 >= 2 but A’s defense will be decremented to 1.
12. You can define your team captain while creating your deck. Your team captain will have +1 in dribble and defense.
13. When the adversary board is empty, your cards will score a goal and you'll win the round
14. If both players don't have cards anymore the round is a draw
15. The number of rounds played to finish a game is unlimited
