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.

Quoi de neuf dans la dernière version ?

The puzzle generator has more cunning and deleted combinations are restored when steps are undone. The changes in detail:

• More logic has been built into the puzzle generator, making it possible for it to generate puzzles that are even more challenging to solve! The new logic is used in Advanced and Expert play modes.

• When the Undo button is used to back-track the steps that have been played, any combinations that were deleted individually are now restored on a step-by-step basis. The same also applies when the help option “undo back to where I went wrong” is used. The ability to delete individual combinations is an optional feature that can be turned on in the settings.

• Some of the help explanations have been improved.
