This is sudoku on a 6×6 grid: place the digits 1 to 6 so each appears once in every row, every column and every 2×3 box. It is quicker than the 9×9 version but uses exactly the same logic.
How this mode works
Tap a blank cell, then a digit from the pad.
A digit that repeats in a row, column or box turns red.
Tips to get better
Look for a row, column or box that already has five digits — the sixth is forced.
For each digit, check where it can still go inside one box. Often only one cell is left.
Use note mode (the pencil) to write candidate digits without committing.
A digit that repeats turns red, so a mistake is visible at once.

Questions and answers
How is 6×6 sudoku different from normal sudoku?
It uses the digits 1 to 6 and boxes of 2×3 instead of 3×3, so games are shorter while the rules stay the same.
