How to play

# How to play Sudolito: 6×6 sudoku rules and your first grid

To play Sudolito, fill the 6 × 6 grid with the digits 1 to 6 so that no digit repeats in a row, a column or a 2 × 3 region. It is a mini sudoku: the rules are those of classic sudoku, but a grid takes only a few minutes, which makes it a perfect daily break.

## The rules of Sudolito

Sudolito is played on a grid of 6 rows and 6 columns, split into six regions of 2 rows by 3 columns. A few digits are given at the start, and they are fixed. Your goal is to fill every empty cell.

- **Each row** contains the digits 1 to 6, once each.
- **Each column** contains the digits 1 to 6, once each.
- **Each region** of 2 × 3 cells contains the digits 1 to 6, once each.

Every grid has a single solution, checked by a solver before it is published. It can be solved entirely by deduction, without ever guessing.

## The daily grid

A new grid comes out every day, the same for all players. Difficulty depends on how many digits are given at the start: around 22 for an easy grid, 17 for a medium one and 13 for a hard one. Sunday's grid is always hard; on weekdays the level varies from day to day.

## Controls

Tap an empty cell to select it, then tap a digit on the keypad below the grid. On a computer you can also type 1 to 6 and move with the arrow keys.

Every digit is checked straight away:

- **a correct digit** locks in with a small animation, and a wave runs through the row, column or region you just completed;
- **a wrong digit** turns red, crossed out, and locks the grid: only the undo button stays active so you can remove it.

The keypad shows how many copies of each digit are left to place, and a check mark once a digit is done. The game controls carry French labels: **Annuler** (undo), **Notes**, **Effacer** (erase) and **Joker**.

### Notes mode

Turn on **Notes** (or press N) to pencil candidates into a cell instead of a final digit. The game refuses an impossible note, meaning a digit already present in the row, column or region, and flashes the cells that block it. When you place a correct digit, it disappears from the notes in its row, column and region.

To note a digit in several cells at once, drag your finger across the empty cells, then tap the digit. **Effacer** clears the notes of the selected cells. Notes are stored on your device only.

### Locking a digit

A long press on a keypad digit (or the L key) locks it: every copy is highlighted on the grid, and each empty cell you tap receives that digit. Handy for placing all the 4s in a row. The lock lifts once the digit is complete.

## A region solved step by step

Take the top-left region (rows 1 and 2, columns 1 to 3). Here is what it holds at the start, with dots marking empty cells:

| Col. 1 | Col. 2 | Col. 3 |
| --- | --- | --- |
| 1 | · | 4 |
| · | 6 | · |

The digits 2, 3 and 5 are missing. Elsewhere on the grid, row 1 already contains a 2 and a 5, in the neighbouring region, and column 1 has a 5 in row 4.

**1. The cell in row 1.** The only empty cell of row 1 in this region can be neither 2 nor 5, which are already in the row. That leaves 3.

**2. The two cells in row 2.** The 2 and the 5 remain. The 5 cannot go in column 1, which already has one, so it goes in column 3, and the 2 in column 1.

The region is complete: `1 3 4` on the first row, `2 6 5` on the second. This reasoning, crossing a region with the rows and columns that run through it, drives almost every grid forward.

## How scoring works

Your score out of 1000 depends on mistakes, jokers and time. On a 6 × 6 grid each mistake costs a noticeable share of the score, roughly 20 to 35 points depending on how many cells were empty.

The **Joker** reveals the digit of the selected cell if it is empty, otherwise another open cell. Jokers are unlimited, but each one costs about 60 points. The reference time is 3 minutes on easy, 5 on medium and 7 on hard: finishing twice as fast earns the maximum 20% bonus.

## Frequently asked questions

</summary>

Every row, every column and every 2 × 3 region contains the digits 1 to 6 exactly once. The digits given at the start are fixed.

</details>

<details>

<summary>How is Sudolito different from classic sudoku?

</summary>

Sudolito uses a 6 × 6 grid with rectangular regions of 2 rows by 3 columns, and only six digits. The techniques are the same as for 9 × 9 sudoku, but a grid is solved much faster.

</details>

<details>

Yes, instantly. A wrong digit turns red and locks the grid until you remove it with the undo button. The mistake still counts in your score.

</details>

<details>

<summary>Can you take notes in Sudolito?

Yes. Notes mode lets you pencil candidates into empty cells. The game refuses impossible notes and removes a candidate automatically when that digit is placed in the same row, column or region.

</details>

<details>

<summary>Does the Sudolito grid change every day?

</summary>

Yes, a new grid comes out every day, the same for everyone. Sunday's is the hardest, with fewer digits given at the start.
