PIXELPOP PLAYER GUIDE

Sudoku Sprint rules, scoring and strategy

Sudoku Sprint uses compact four-by-four puzzles instead of a traditional nine-by-nine grid. Every row and column must contain the numbers one through four exactly once. The smaller board makes each round quick without removing the logic that makes Sudoku satisfying.

Rules and objective

Select an empty square and choose a number from one to four.
Each row must contain every number once.
Each column must also contain every number once.
Completing a valid board advances the level and produces another puzzle.

How scoring works

A solved grid earns a completion award that grows as the level increases. Progress is saved, so later visits can continue the rising difficulty instead of returning to the first puzzle.

Strategy tips

Start with a row or column that already contains three different numbers.
Use elimination: if three values are visible, the missing fourth value is forced.
When uncertain, compare both the row and column before entering a number.

Controls and device support

Tap or click an empty cell, then choose a number. The four-by-four layout remains readable on small screens and does not require typing.
