Browsing puzzles just got smoother: tap into any category to scroll quickly. Use the new Select, Select All / Deselect All and Clear buttons to quickly clear puzzles to play again.
If you're on iOS 26, Hint and Undo are now always one tap away even if your screen is small or your text is large — no more hunting in the overflow menu.

- Board hints just got a serious upgrade. 7 different strategies now help you find that next move when you're stuck. Even the sneaky locked triples and quads.
- Large puzzles now gently remind you about pinch-to-zoom. Just the once, we promise.
- Fixed a crash if you were a little too eager tapping the store before it finished loading.
- Assorted behind-the-scenes polish. The kind of thing only our QA team and designer notices.

Three new volumes of puzzles (sorry for the delay for those who have asked!). These ones also have a range of new sizes, though similar difficulties. Also fixes some minor bugs (like white areas in dark mode in landscape on newer phones) and generally updates everything for the latest Apple iOS releases.
As always, email support@eggheadgames.com if you have any questions or suggestions. We love to hear from you and respond promptly!
4.7.0 2023. 04. 09.
Faster "Back" and "Next Puzzle" buttons. iOS 15 fixes for transparent top bar and an errant separator line below stories. Removed the transition text below the clues explaining where the Clear button has moved to (tap Puzzle while playing a puzzle to re-read the story or clear the puzzle).

A new Zen Mode option hides all references to badges and hint counts. Clearing the board while playing is now easier to find (tap Puzzle then Clear). The clue area is now easier to scroll. Small tweaks include: badge explanations, moved hint count under Hint, improved the iPad main screen layout, improved dark mode support for iOS 13 and higher, fixed a rare crash.
All of these changes were inspired by customer suggestions and feedback. Thanks to all of you! Email me at support@eggheadgames.com anytime, or use the Help – Contact Support option in the app. I love to hear from you and reply to every email.
Happy puzzling!
Cheers, Michael

Improves row, column and label highlighting. If you tap a label, zoom and tap a cell, it will continue to highlight the row/column. This makes it easier to keep your place when the grid is zoomed and was a recent customer request (thanks!).
Email support@eggheadgames.com anytime if you have questions or suggestions, or if you need help with a puzzle. Cheers, Michael
4.6.7 2021. 08. 09.
Improved the Story display and added an option to disable it showing automatically for every new puzzle. Added "No Hints" badges to the the Solved Puzzles list as a visual addition to the existing text. Random hints are better distributed across the grid. Fixes a badge color problem for iOS 12.
If you have questions or problems, tap Help – Contact Support in the app, or email support@eggheadgames.com, or find us on Facebook. Your suggestions make the app better for everyone. Happy puzzling, Michael.
4.4.4 2021. 03. 11.
Get Hint now suggests a cell even if no logical hints are available. Moves Restore Purchases to the bottom of the screen to separate it from the unrelated Hidden & Solved Puzzles links. Improves dark mode support for iOS 12.
4.3.7 2020. 12. 12.
New puzzles are available for purchase: 3 volumes of 30 puzzles each. There are new features too! Now you can tap on a clue number to mark it as "in progress" (you can still separately tap on the text of a clue to mark it as done). The Story has been moved to a separate button so it's easier to scroll to the start of the clues while solving. There are also some small layout and formatting improvements and a couple of rare bugs were chased away.
4.3.6 2020. 11. 25.
60 new puzzles available as 2 additional purchases from the "Add Puzzles" button. Also corrects some label ordering in the prior batch of 30 puzzles.
4.3.0 2020. 09. 10.
Detects and provides hints for any unused "transpositions" on the board. These are a "mechanical" hint based solely on the current board position, but they are commonly overlooked and a useful aid to solving. (See the link the User Guide for solving logic puzzles and look for the Transpositions section for more information.) Also, an accidental tap of the Hint button will no longer cost a hint, and finally there is a new feature to report on mistakes without clearing them.

4.2.12 2020. 08. 04.
Thirty new puzzles are available for purchase for those keen puzzlers who have run out! A new hint that checks for missing "True" cells. Replaced an inappropriate puzzle. Recognizes solving "down the left" side of the grid as well as the existing "across the top". Fix a rare crash when updating from last year.
4.2.11 2020. 07. 12.
Improved the typography of apostrophes (vs quotes). Fixed 4 broken puzzles in the recently added volumes 14 & 15. Hides the "Add Puzzles" button if all the puzzles have been purchased.
Use Help – Contact Support if you have questions or think there's a problem with a puzzle, or email a screenshot to support@eggheadgames.com. I love to hear from you! Cheers, Michael
4.2.2 2020. 05. 01.
Fix & replace some of the latest puzzles that had overlapping labels. Adjusted some labels to display more clearly.
Thanks to the customers who pointed this out and sorry for that lapse. Tap Help – Contact Support if you notice anything else amiss (or if you just want to say hi). Cheers, Michael @ Egghead Games
4.2.1 2020. 04. 23.
Hint and Undo buttons are easier to find and use, fixing accidental puzzle exits. Images are sharper on large screens. Corrects an error in one of the new puzzles ("Don't Fence Me In").

4.2.0 2020. 04. 22.
Improves Dark Mode badge display. Fixes 3 of the recently added puzzles. Fixes a hang when left-side-swiping a zoomed in puzzle.
