Which game to open first
DIGIGMA has six live games. Here are three starting points: Sudoku, Killer Sudoku and Binary Puzzle. You do not need a personality test to pick one. You need an honest answer to a smaller question: what do you already know, what kind of constraint do you enjoy, and how long is the sit?
All three have one solution. None of them needs a guess. Easy is the honest first band on each. The rest is taste.
If you already know Sudoku
Start with Sudoku. DIGIGMA uses the classic 9×9, nothing else. You already have the scans: last empty cell, only-one-place, only-one-digit. Open Easy. Let the site’s Draft tool be the pencil marks you already use, or ignore it until a cell has two leftover candidates.
The how-to will not talk down to you. It names the same first moves and stops before folklore. How to play Sudoku.
If you like counting and combinations
Killer Sudoku is the same 9×9 with cages instead of given digits. You still place 1 through 9 once per row, column, and box. You also ask which small sets of digits can make a printed total, without repeating inside the cage.
This is the board if Sudoku feels solved as a sensation and you want a tighter local puzzle — not a harder Sudoku, a different one. Easy Killer is still Easy. The empty-looking grid is a trick of the clues, not a dare. How to play Killer Sudoku.
If you want two symbols and a smaller grid
Binary Puzzle is 0s and 1s. 6×6 is the short sit; 8×8 is the same rules with more room to go wrong. You watch halves, triples, and whether two lines would match.
Choose this if 1-through-9 feels like the wrong alphabet tonight, or if you have ten minutes and want a board that finishes inside them. The strictness is local and visible. You do not need a Sudoku past. How to play Binary Puzzle.
Start on Easy
Bands describe the kind of reasoning, not how empty the picture looks. Easy is not a children’s label. It is the band where the first scans in the how-to are enough, most of the time. Medium asks you to hold more. Hard and above are for when Easy has become a walk.
If a first grid feels noisy, you did not fail the site. Open a lower band, or a smaller Binary Puzzle. You can also leave it and come back. The unfinished board waits.
You can switch
Stuck is a board you cannot see through yet. A different family can reset the eye. Leave the Sudoku; open a Binary Puzzle; return later. DIGIGMA will not scold the unfinished one. Three games is enough to do this without hunting.
If you are sitting with someone new, stay on Easy and let them tap. Point at the how-to instead of reciting. One short sit together is enough; then they can play on their own.
Three kinds of board is the comparison if you want the sensations side by side. Games is the catalogue. One Easy grid is a complete visit.
