Hi,
I may have something relevant, although it is significantly larger in scope than the smaller projects you mentioned.
NEXOVANT POKER is a completed and operational online Texas Hold'em platform developed as a full client/server product rather than a prototype.
Tech stack / scope:
• Unreal Engine 5 / C++ native Windows client
• ASP.NET Core / .NET backend
• Microsoft SQL Server
• Server-authoritative multiplayer architecture
• 4- and 8-seat poker tables
• Tournament functionality
• Player accounts, persistent economy and leaderboards
• Integrated shop / Stripe commerce
• Daily rewards and reward systems
• Moderation, reporting and administration systems
• Automated players / bots
• Build, deployment and client update infrastructure
• Website and technical documentation
The acquisition would include the complete source/project files, backend, database architecture, website source, original brand/graphical assets, operational tooling and associated software/IP rights as defined in the final agreement.
It is currently pre-revenue, so this is specifically a technology/IP acquisition rather than the acquisition of an established revenue-generating business.
Asking price: €49,500.
I realize this is considerably above the inexpensive projects you specifically welcomed. The price reflects the scope of the completed technology stack and the development work involved — this is closer to an AA-scale independent software/game project than a small indie prototype or abandoned game-jam project.
The platform can currently be evaluated through a live demonstration, and technical due diligence / an architecture walkthrough can be arranged before any acquisition.

If that scope and price range are outside what you're looking for, no worries at all — I thought I'd mention it since your interest in complete source code and IP transfers is otherwise a very close match.
