Coffee Break — 100 Sudoku Puzzles | Puzzle Studio Pack

⚠️ Requires 7ThirtyWorld Puzzle Studio (sold separately). This is an expansion pack — a puzzle file that loads into the Studio app. It is not a standalone game and will not open on its own.

100 sudoku puzzles. Every one has exactly one solution, and that has been proved, not assumed.

Fifteen-minute puzzles that ask for a second look but never turn into a fight. These need hidden singles — spotting that a digit has only one place left in a row, column or box, even when that cell still looks like it has options. The step up from scanning, and the tier most people settle into.

What you get

• 100 puzzles, each with 33 to 39 starting clues
• Guaranteed unique solutions, confirmed by exhaustive search on every single grid
• Graded by technique. Every puzzle here genuinely requires hidden singles — none can be finished by simple scanning alone, and none needs anything harder.
• All 100 grids are different, and different from every other pack in the collection
• Ordered gently — the pack opens with the most generous grids and works down.

How it plays in the Studio

Pencil-mark notes, live duplicate highlighting, and a keypad that dims digits once all nine are placed. Nothing is rejected as you type — a row, column or box turns green the moment it is complete and correct.

How to load it

Open 7ThirtyWorld Puzzle Studio, choose Add a pack, and select this file — or just drag the file onto the app. It joins your library permanently and works completely offline.
