Description
The acclaimed logic game for fans of challenging puzzles. Here's what some reviewers have been saying:
• “The ONLY iOS game I've never gotten tired of”, Reddit review Apr 2024
• “This is, hands down, THE best logic game on the App Store”, US App Store review Mar 2023
• “Best brain workout”, US App Store review Jan 2023
Known by the names Doppelblock and Smashed Sums, this type of logic puzzle was first seen in the Japan Puzzle Championship 2006. On paper, the puzzles can be pretty bewildering 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!
Useful to know: even though there are numbers involved, all puzzles can be solved with pure logic, no mental arithmetic is required.
So 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 1.60.1
Two new packs of quirky puzzles and a new pack of premium 9x9 puzzles, along with some other small improvements. The changes in detail:
- Three new packs of puzzles have been added in this version: 2 packs of quirky puzzles and a pack of premium 9x9 puzzles. These special types of puzzle are the hardest to generate using the built-in puzzle generator, so the packs offer a more convenient way to play these sorts of puzzle.
- The difficulty ratings for puzzles in the existing quirky packs and 9x9 pack have been re-assessed and revised in some cases. The aim is to ensure that the difficulty ratings for puzzles in these categories are consistent. The new assessment is based on an evaluation of the logic that is needed to solve the puzzles. The puzzles themselves have not changed, so the revised difficulty ratings only affect the scoring. Some packs have also been re-ordered a little.
- When full dark mode is in operation and a puzzle starts with pre-filled blocks, the blocks can be seen more clearly against the background of the empty puzzle. Pre-filled blocks only occur in 9x9 puzzles generated by the puzzle generator.
- More improvements to the way the difficulty is estimated for new puzzles generated by the puzzle generator.
- A fix for issues with scrolling when switching between puzzle pack categories.
- A fix for the way candidate values are added or removed from a group of squares for the case of when a previous update left the squares with less candidates than number of squares.
Version 1.60.1 contains some additional small changes:
- Further improvements when estimating the difficulty of a new puzzle and when scrolling to position in the context of puzzle packs.
- A change to the follow-up page when a puzzle in the Challenge Trail or a puzzle pack is paused during play. Instead of returning straight back to the overview page as before, the page for a paused puzzle is now shown. This makes it easier to resume play. It also makes it more likely that the previously played steps can still be undone one by one. This flow is the same as how it works when playing puzzles generated by the puzzle generator.
