How do I use the pencil mark feature to make notes in squares?
Tap the pencil or note mode button (usually near the number pad) to enter small numbers in a square, helping you track possibilities. This is great for tough puzzles where you need to test options without committing to a final answer.
What do the 'auto-check' and 'highlight duplicates' toggle switches in settings do?
Auto-check automatically flags incorrect numbers as you place them, while highlight duplicates shades repeated numbers in the same row, column, or box. If you accidentally toggle one off and your puzzles look different, just go back to settings and turn it on again.
Why does the hint button sometimes only highlight a row instead of giving me a number?
The hint button provides a gentle nudge by highlighting a row or area where a number can be placed, rather than giving you the exact answer. If you need more direct help, try using the 'show number' hint option if available, or save hints for when you're truly stuck.
How can I stop ads from popping up at the worst moments, like when I'm about to place the last number?
Ads are frequent in the free version, but you can remove them entirely by purchasing the one-time in-app ad removal option. This will prevent interruptions and accidental taps that take you to sketchy websites.
How does Supreme Duelist compare to other Sudoku apps like Sudoku.com or Classic Sudoku?
Supreme Duelist stands out for its clean, senior-friendly design with big buttons and soft colors, making it easier on the eyes than flashier alternatives. However, its hint system is less helpful than some competitors, and ads are more intrusive unless you pay for removal.
