The problem UNO STARK solves

Real-Time Gameplay Delays:
Traditional online card games often face delays in transactions, which can disrupt the flow of the game, especially with many players. Starknet UNO eliminates this problem by providing instant transactions and real-time updates.

Scalability Issues:
Most online games struggle to maintain performance as the player base grows. Starknet ensures that the game runs smoothly, even with multiple players, thanks to its Layer 2 scaling solution.

Game Integrity:
In traditional online games, players often worry about cheating or game manipulation. With Starknet’s blockchain-based system, every action is recorded on a decentralized ledger, ensuring transparency, fairness, and trust.
High Transaction Costs: Conventional online games incur high fees for in-game actions. Starknet reduces these fees, making it cost-efficient for players and developers.

Challenges we ran into

Blockchain Integration Complexity:
Integrating blockchain technology into a fast-paced game like UNO was initially challenging. We had to ensure that the real-time gameplay and the decentralized nature of the game could coexist without causing lag or delays.

Smart Contract Optimization: Designing smart contracts that can handle the game logic and actions (such as card creation, game start, turn management) efficiently while minimizing gas costs was a key challenge.

User Adoption:
Introducing blockchain technology to a traditional card game audience was a hurdle. We had to ensure that players could enjoy the game without needing deep technical knowledge of blockchain.

Performance Tuning:
Balancing the speed of Starknet with the game’s requirements, especially when processing multiple player actions simultaneously, was critical to ensure the game remained responsive.
