Easy puzzles can be solved with just this idea

53791862
Only 4 is missing. The empty cell must be 4.

Every column, every row and every bold 3×3 box holds 1 to 9 once each. So when you find a column or row filled up to 8, the empty cell takes the missing digit.

The bottom row has 1, 2, 3, 5, 6, 7, 8 and 9, and only 4 is missing. The empty cell must be 4. Easy puzzles can be solved to the end just by following cells like this, one at a time.

Tips for Easy

  1. Start by picking one digit and following it. Look at all the 1s on the board, then in a box that has no 1 yet, find where 1 can go. You will soon find a cell you can decide.
  2. Look first at rows, columns and boxes that are well filled. The fewer the gaps, the easier the missing digit is to see at a glance.
  3. After placing a digit, look again at that cell's row, column and box. The digit you just placed often settles the next cell.

Techniques for Easy

How the levels differ

Levels are set not by how many digits are given at the start, but by the reasoning a puzzle needs.

Levels and key techniquesTypical timeClues
EasyJust find the missing digits5 to 20 min38
MediumWrite notes (candidates) and narrow down15 to 30 min30
HardRemove candidates with pairs30 min to 1 hr27
OniPatterns that span the board, such as the X-Wing1 hr or more28

Hard and Oni start with about the same number of clues (averages of 27.2 and 27.6). Even with many digits, you cannot get far in Oni without finding patterns that span the board, such as the X-Wing.

The game has one more level above Oni, called Master, making 5 levels in all. Master can only be played in the game.
