Why no guessing matters
A good logic puzzle never asks you to gamble. On Suvi, every daily is generated and then checked by a solver before anyone sees it: each sudoku has one solution, each minefield can be cleared without a guess, each chess puzzle has a forced mate, each sorting room has a proven best score. If you're stuck, the next step exists; it's a matter of finding it.
That is also what makes the daily share card fair: everyone had the same puzzle and the same chance. Stuck? The guides teach the patterns: sudoku techniques, minefield patterns, spotting checkmates.
