I used to enjoy doing the occasional Sudoku puzzle and was amused when a hexadecimal version of it started doing the rounds.

Just for fun I reproduce here a typical puzzle that I invite other forum members to have a go at. The usual Sudoku rules apply however this one requires 0-9 and A-F in each 'block' to complete - the task is to reveal the 'code' that would appear in the greyed-out boxes.

Some will recognise the provenance of this puzzle so no cheating!

Hello! I enjoy working Sudoku puzzles from the paper every day. This is a new concept for me. I believe I can solve it, but it will take a long time. I will enjoy trying.

Can we have a binary one for beginners?

I believe I have the solution. How can I display it?

Please don't spoil the game. I suggest you send your solution to @kellys_eye via a private message (klick on his name, then klick 'start a conversation').
I have sent him my solution, too.

Only a hint: the checksum of my result is 20

Croykee Mick.... it took me FOUR attempts to get the solution! When I make a mistake I find it impossible to roll-back my numbers to establish where it went wrong so inevitably have to start from scratch!

Still, I finished it today!!! And the checksum of 20 fits my answer too.

Congrats on a speedy solution Harald.

No PM received but a 'checksum' (total the individual completed numbers in the grey boxes) will give a right/wrong answer if you want to let us know.

Well we've had THREE MONTHS to finish that one - time for another. Let's see if we can do a bit better!

It's a question mark.

5-2=3
4-1=3
remaining digit 3
cant be 6-3 as 6 not allowed in '?' cell
so must be
3-0=3
...... or is logic too "fuzzy"??

It's the gear pattern in a manual car. R is for reverse

No way! They wouldn't allow a 'straight' move to reverse from a forward gear - it's always on a dog-leg.

It could be another 5 - the sum of the diagonals in the first four squares.

I vote for 3 - the sum of each row is 9 then.

It doesn't include the mechanical geometry. It's just the pattern. Like this pictures also.

Point taken - such gear layouts usually include a mechanical 'link', in many cases a collar under the gear knob that requires the user to 'pull/lift' to enable the gate movement, to select reverse.
