Improvements in the area of puzzle packs and some changes to the way the number buttons work. The changes in detail:

• Puzzle packs can now be reset individually, instead of all packs in the same category having to be reset together. The menu option “reset puzzle packs” brings up a dialog in which the packs to be reset can be selected freely.

• When playing the puzzles in puzzle packs, the way that the next puzzle is selected has been changed. It now works more sequentially, always proceeding forwards where possible. When all puzzles in a pack have been solved, the search proceeds forwards to the next available puzzle pack, instead of jumping back to the first pack.

• When a puzzle in a puzzle pack is paused, the page with the button for continuing play now includes a new button to “skip to next puzzle”. This provides a more convenient way to proceed to the next puzzle in a pack, rather than having to go back to the overview of puzzles and selecting the next puzzle manually.

• The way the number buttons switch between being active or inactive has been changed. The buttons are now only active for the numbers that are still considered to be candidates, they are inactive for numbers that have already been eliminated. This helps to prevent numbers from being mistakenly re-added to a square, or to a group of squares. It also makes it easier to see which combinations fit a group of squares that have been selected together.

• Depending on playing strategy, some players may prefer to have the number buttons working as they did before. The setting “tie number buttons to narrowed candidates” makes it possible to choose, whether the buttons work in the new or old way. This new setting can be found in the settings section for “optional features”, it is on by default (= new way of working).

• When a single square is selected and the candidate values are updated by tapping the number buttons, values that are eliminated are now highlighted with orange/pink. This is consistent with the way the numbers are highlighted when multiple squares are selected and operated on together.

• When a single square is selected and pencil mode is active, the number buttons no longer appear with orange highlighting for all buttons. Instead, the buttons use the same highlighting as when pencil mode is not active.

• Added dark and tinted app icons for iOS 18 / iPadOS 18.

• Added some measures that might help to prevent the Game Center icon from being shown at the wrong time when the app is brought back into action after having been suspended for a while.

• Some corrections have been made to the way that candidate values are restored to related squares when the selected square (or group of squares) is cleared by tapping repeatedly, or by tapping the clear button.

Version 1.62.1 includes some additional fixes:

• When a 9x9 puzzle with pre-filled blocks is reset, the pre-filled blocks should not be cleared.

• When the setting “Show if numbers add up correctly to the clue values” is turned off, there should be no sound or haptic feedback when numbers do not add up correctly.

• When the setting “Show if numbers add up correctly to the clue values” is turned on and multiple squares have been selected together, checks on numbers adding up correctly are suspended while the selection is still active. This will help to prevent false alarms of an incorrect sum when players choose to tap in candidate numbers one by one, instead of eliminating numbers using double tap.
