Celebrating 50 releases of Sumaddle!

Version 1.50.0 is the 50th release of the app! To celebrate this milestone, there are some significant changes in this release:

• The Challenge Trail has a new look, more consistent with the woodland themes used elsewhere in the app.
• New categories of puzzle pack have been added for Quirky and Scary puzzles, each with 3 brand-new packs. The Quirky packs contain out-of-the-ordinary puzzles, the Scary packs are aimed at skilled players and include a pack of premium 9x9 puzzles.
• A new kind of selector is used for switching between the categories of puzzle packs and the contents of the packs are described in more detail.
• Naming changes: the section Puzzle Sets is now called Puzzle Packs, the section Random Play is now called Puzzle Generator.

More details about the quirky puzzles and the premium 9x9 puzzles can be found in the FAQ section about in-app purchases.

A number of other corrections and improvements are also included in this release:

• Better support for dark mode in the Introduction and Challenge Trail sections.
• An improvement to the way the next puzzle is selected in the puzzle packs, to avoid going back to skipped puzzles after the app has been restarted.
• An improvement to the way the puzzle packs scroll into position, with the aim of always bringing the last-played puzzle into view.
• An improvement to the way the built-in help determines where the next step can be played, in order to skip small changes that are not important for making progress.
• A fix to prevent the puzzle generator from occasionally whirring forever.
• A blur effect is applied to the puzzle grid if the app is put into a suspended state when a puzzle is in play, so that it is not possible to study the puzzle while the timer is paused.​
• Further corrections and improvements to the help explanations.
