The cost of developing a rummy game varies based on your specific requirements and feature set. A basic single-platform version typically starts at $5,000 to $10,000, which is ideal for testing the market. However, for a professional, feature-rich game with cross-platform capabilities, robust security, and multiplayer functionality, expect to invest between $20,000 to $100,000.
Factors influencing the cost include platform selection (iOS, Android, or web), complexity of features (AI opponents, tournament systems), security requirements, and real-money gaming integration. Upfront quality development can save significant costs for future updates and maintenance. A clear roadmap and expert guidance can further optimize your investment.
