The Only Answer

Nine numbers. Nine boxes. None repeat. One solution.

Not one of several. One.

I started playing Sudoku at forty — scared, if I'm honest, of my mind getting slower. Everyone said play Sudoku. So I did.

And then something unexpected happened. I started enjoying it. Not the completion. The mystery. The way a grid of mostly empty squares could hold, somewhere inside it, an absolute.

The game teaches you something counterintuitive. You never really know where a number goes. You only know, gradually, where it cannot go. You eliminate. You narrow. You close off every square that cannot hold this number until — sometimes slowly, sometimes with a small shock of recognition — only one square remains. However improbable it looked. That's where it goes.

This is not how we solve most things. We look for the answer. Sudoku teaches you to remove everything that isn't the answer until the answer is the only thing left.

And then there is the other moment. The one that arrives after a game you thought you'd played well. Somewhere in the final squares — a repetition that was never to be. A number sitting in a place it cannot sit. You look at it and the feeling isn't quite frustration.

It's — how did I not see it.

Because the mistake was always there. Placed quietly, confidently, early. While you were certain. The error didn't arrive when you found it. It arrived long before, wearing the same face as a good decision.
