• “Brilliant puzzle game”, UK App Store review Apr 2025 • “Best Puzzle Game I’ve Ever Played”, US App Store review Jan 2025 • “The ONLY iOS game I've never gotten tired of”, Reddit review Apr 2024 This type of logical puzzle was first seen in the Japan Puzzle Championship 2006 and is sometimes known as Doppelblock, or Smashed Sums. When played with pencil and paper, these puzzles can be hard work to solve. Sumaddle changes that by adding the essential element of interaction. This transforms the puzzles into intriguing brain teasers that unfold before your eyes. Each puzzle has a unique solution. Finding the solution involves fitting the number combinations to the clues. The app makes it easy to view the possible combinations, you don’t need to do any sums in your head. Instead, you can focus on using logic to narrow down the combinations and find a fitting arrangement.
