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.

Some reasons why you will enjoy playing Sumaddle:

Quoi de neuf dans la dernière version ?

This version includes some upgraded puzzle packs and various small improvements. The changes in detail:

• Many of the puzzles in the Scary puzzle pack category have been replaced with new puzzles that reflect the difficulty ratings more accurately. This applies to puzzles in the Assorted and Very Difficult packs, as well as the free selection. Players who already played the puzzles in these packs can now enjoy playing all the new puzzles at no extra cost.

• When a group of squares is selected using a drag gesture, any gaps in the same row or column are automatically filled, if possible. This works the same way as when a clue value is tapped, so blocks are added automatically if the number of empty squares exactly matches the number of missing blocks, or empty squares are populated with candidate values if two blocks are already present.

• When a group of squares is selected using a drag gesture, the combinations for the corresponding row or column are always shown automatically, even if no combinations were already showing.

• Fine tuning to the way the puzzle generator determines the difficulty of a new puzzle when running in Advanced and Expert play modes.

• The setting that allowed the puzzle generator to use permutation logic with “no limits” has been dropped. This used to be a way of generating more difficult puzzles, but the puzzle generator is now capable of generating very difficult puzzles without needing to resort to such measures. Puzzles that involved elaborate permutation checks were usually not much fun to solve anyway.

• More improvements to help explanations.

• Styling change to the panel showing the points scored for a completed puzzle. This panel now looks more like a button (iOS 26 and above). Tapping the panel is a quick way to view the leaderboard - this has always been the case, but until now it was less apparent that the panel is tappable.
