Question 1

Does every board have one answer?

Accepted Answer

Yes. Before a board is shown, a solver works from the clues alone and keeps the board only if exactly one grid fits them.

Question 2

Do the boards draw a picture?

Accepted Answer

No. Boards are random, so the finished grid is an abstract pattern. The puzzle is the logic, not the picture.

Question 3

Why did a clue cross out when I'm not finished?

Accepted Answer

A clue crosses out when its own line's runs match it. That doesn't promise every cell is in the right place: another line may still disagree, and then something has to move.

Question 4

What does a hint do?

Accepted Answer

It never fills anything in. If a cell is wrong it points at one, a single cell at a time; otherwise it highlights the next cell its row or column settles and says whether it is filled or empty. The results card notes how many you used, and that's all.

Question 5

Where are my bests and streak saved?

Accepted Answer

In your browser's localStorage: your fastest solve for each grid size and your daily streak. They never leave your device.

Question 6

Can I play with a keyboard?

Accepted Answer

Yes. Use the arrow keys to move around the board, Enter or Space to cycle a cell, and X to mark a cell empty. U undoes a move.
