Mini Sudoku
A bite-sized single-player number puzzle. Fill the 6×6 grid so that every row,
every column, and each of the six 2×3 boxes (2 rows tall, 3 columns wide)
contains the digits 1 through 6 exactly once.
How to play
1.
The grid starts with about 16 cells already filled in. These givens are
shown in bold and cannot be changed.
2.
Click any empty cell (or a cell you previously filled) to select it.
3.
Click a number 1–6 from the palette under the board, or type the digit on
your keyboard, to place it in the selected cell.
4.
Press Backspace, Delete, or 0 — or click the Clear button — to
empty the selected cell.
5.
Toggle the Pencil button to make notes: while pencil mode is on, tapping
a number adds (or removes) it as a small candidate mark in the selected
cell, so you can jot down the possibilities you are weighing. Tap the same
number again to erase that mark. Candidate marks are just notes — they clear
automatically as soon as you place a real digit in the cell, and they are
saved with your game, so they are still there when you come back to it.
6.
The puzzle is solved when every cell holds a digit and no row, column, or
box contains a duplicate.
Conflicts
Sudoku traditionally forbids illegal placements. This implementation lets you
make any move and shows mistakes instead of blocking them: a cell whose digit
duplicates another in the same row, column, or box is highlighted in red.
Use the highlights to deduce the correct answer.
Winning
Fill in all 36 cells with no conflicts to win. The puzzle has no scoring or
time limit — the only goal is a fully consistent grid.
Tips
•
The 6×6 grid is a gentler introduction than the classic 9×9 — a great way to
learn the technique before scaling up to full
Sudoku.
•
Look for rows, columns, or boxes that already have many digits filled. The
remaining cells have fewer possibilities.
•
Scan each row and column for the digit you want to place — if it already
appears, you can rule out cells in that line.
•
Use the Pencil button to note candidates in small print, and rely on the
red conflict highlights to spot mistakes as you go.
