2:07 What takes others so long? Do they allow incorrect moves? That would be like the police allowing crime.

Very slow 5:00

DotCom, for comparison:

- I start the clock before looking at the puzzle,
- I allow incorrect moves, and
- I don't fill in the possibility grid before starting (it would take too much time with the clock running anyway).

When I play, I want to *deduce* More...

Jyrki, that's the way I play (and generally far more slowly than you), too. After much effort, I'm starting to find the Toughs less taxing, usually by looking for hidden doubles and triples (or sometimes quadruples) and proceeding by process of eliminating possibilities one by one. And which device (iPad, iPhone or laptop) I use also affects my speed.

Thanks, Jyrki, for laying out your strategy. I don't allow incorrect moves, but consider using it to enter random #s until you find the right one to be cheating. Placing an incorrect # without knowing, quickly gets me into a hopeless mess that I can't unravel. Not fun. That's why, to keep it fun for me, I don't allow incorrect moves.

I don't use incorrect moves unless by accident. I start with number one and work my way through to nine then fill in the blank squares if I have worked out the correct number. I start the timer once I have worked out the first move.

Maybe it's because it's so late and it's been a long hard day but I struggled with that one - 6:07. Hi everyone.
