About Plus15 Daily Logic Puzzle Game
+15 is a daily spatial logic puzzle built around a simple constraint: the grid must be divided into exactly 15 regions, and every region must add up to 15. Regions can vary in size. Some may contain just two tiles, while others require three or more. All number tiles must be used, and each puzzle has one unique solution. There is no guessing ... only deduction. How it works: • Partition the grid into exactly 15 regions • Each region must sum to 15 • Regions vary in size • Every tile is used • Each puzzle has one valid solution Features: • A new daily puzzle • Easy, Medium, and Hard difficulties • Clean, distraction-free design • Optional hints when you’re stuck Sometimes being right leads you wrong. Find the unique solution.
