• “The ONLY iOS game I've never gotten tired of”, Reddit review Apr 2024

Known in the puzzling community by the names Doppelblock and Smashed Sums, this type of logic puzzle first appeared in the Japan Puzzle Championship 2006. On paper, the puzzles can be mind-blowing to solve, but the Sumaddle app adds the essential element of interaction to transform them into intriguing brain teasers that unfold before your eyes.
Take your time and enjoy puzzling your way through more than 120 free puzzles, ranging all the way from easy to very difficult. If you get stuck or make a mistake, the built-in help will get you going again. The help explains the logical reasoning at each step, making it a great way to learn how to solve the puzzles. Use the help as much as you like, it’s also completely free. Even with so much free content, you won’t be bothered by ads - Sumaddle is completely ad-free!
What’s New
Version 1.59.2
More small improvements:
• When the setting “Allow combinations to be deleted individually” is turned on, the space freed up by deleting individual combinations is better used for showing the remaining combinations. This will particularly benefit players who are playing large puzzles on small devices.
• When the leaderboard display style is set to “Top scores” (which is the default) and the player’s own score is outside the top 100, more scores from other players are now shown around the player’s own score. The leaderboard display style can be selected in the system settings for the Sumaddle app.
• The section of the introduction that was previously called “Tips” has been renamed to “Strategy”.
Version 1.59.2 also includes some small cosmetic improvements and mechanisms for investigating scoring irregularities.
