+15 is a fun daily spatial puzzle that is simple but not easy! Built around one rule: divide the grid into exactly 15 regions, and every region must add up to 15. Regions vary in size, every tile is used, and each puzzle has one unique solution. Play a new daily puzzle across Easy, Medium, and Hard difficulties. Clean, distraction-free, and built for deduction... not guessing.

Team building World Cup experience for remote teams (B2C and B2B). It is a SAAS ready to be sold to customers, I just don´t have the skills or time to sell it. I can send screenshots of the b2c, b2b and admin dashboard to show how smooth the game runs and how easy it is to create a game for a b2b client (SAAS). B2B demo page: www.kickpot.app/preview

"+15 is a finished daily puzzle app with a simple, original mechanic and room to grow. I’m selling because the game is likely better suited to someone with existing distribution, ASO experience, social reach, or a portfolio of puzzle games. The core product is built, monetization is in place, and early users have already solved 600+ puzzles. The main opportunity is marketing... getting +15 in front of more daily puzzle players."
