About Sudoku Forever

Sudoku Forever is a Sudoku game where you fill in the grid by choosing numbers for its cells. You can select a number with the mouse, use the search method, or click a cell and then choose a number. Hints indicate whether your moves are correct.

Levels and feedback

The game has 40 levels with gradually increasing difficulty. Empty cells are blue, correct moves are green, errors are marked red, and pre-filled numbers that cannot be changed are grey. Pleasant music accompanies the puzzles.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
