Sudoku Magnetic Fridge Game (with 30 free puzzles)

Make the holidays more fun by having a nice game of Sudoku with others while enjoying your coffee (or tea).
Join around the refrigerator, then discuss and amaze others around you with your sharp reasoning skills and elevated insights into logic !
Or solve Sudoku puzzles together and test each others Sudoku-solving capabilities.
Or print the game twice and have a contest between two people/groups and compete in the intellectual realm.

I've supplied two PDF-files with 30 Sudoku puzzles, 15 Easy ones and 15 Medium level ones, based on standard Sudoku rules:
- each row should have numbers 1-9, no repeats.
- each column should have numbers 1-9, no repeats.
- each 3x3 quadrant should have numbers 1-9, no repeats.

The puzzles I supplied can be solved using the basic three solution strategies:
- Scanning (basic Sudoku)
- Row-Column-Combination
- Single Candidate
For examples of these strategies see the images.

The Easy (One Star) puzzles are characterized by the fact that at every stage of solving there are always multiple clues to be found using the aforementioned three strategies.
With the Medium (Two Stars) puzzles there are regular points along the solution route when there's only one such hint available, increasing the difficulty level.

Use the supplied arrows 3D models to leave information about your last found clue so others can continue the puzzle from there at a later time.
There's also the possibility to use the analysis tiles to point out the solution strategies to each other.

I've uploaded a set of tools to help dispense magnets and press them into place.
Also a lot of thought and engineering effort has gone into a neat tile dispenser to store your Sudoku tiles and eject them easily and reliably at the press of a button.

You'll need Ø10x2mm magnets and (many) Ø4x2 magnets to assembly everything:
Amount of magnets for Basic Game:
- 4 x Ø10x2mm
- 81 x Ø4x2mm

See (PDF-) drawings for assembly instructions and additional magnet amounts when deciding to also 3D print the additional tools and dispensers.

In the images you'll find two bonus Easy puzzles, as well as their solutions.

For every 5 boosts received on this page I will upload another 30 puzzles: 15 easy and 15 medium ones.
