Question 1

What is Sudoku Force?

Accepted Answer

A free forced-move Sudoku game. Each round shows a nearly-complete 9×9 grid with one cell highlighted. Exactly one digit fits the highlighted cell given the row, column and 3×3 box constraints. Pick the right digit to build a streak; miss once and the run ends.

Question 2

How is the answer validated?

Accepted Answer

A pure function called verifyForcedNumber checks that your chosen digit is the unique legal value at the target cell. It scans the row, the column and the 3×3 box for every digit 1-9 and confirms only one survives. No preset answer flag · the validator is the sole oracle.

Question 3

Do I need to solve the whole board?

Accepted Answer

No. The whole point of Sudoku Force is to train the single "forced move" skill in isolation. You never have to solve a full Sudoku; you just spot the next forced digit, over and over. Full-Sudoku skill comes as a side-effect once the forced-move scan becomes automatic.

Question 4

Will this make me faster at full Sudoku?

Accepted Answer

Yes · the forced-move scan is the rate-limiting step in most Sudoku solves. Players who do a few hundred Force rounds typically see their full-Sudoku times drop significantly because the basic step happens without conscious effort, leaving cognitive bandwidth for the harder steps (X-wings, naked triples).
