🧮Logic puzzles
Careful reasoning matters more than quick reactions in these logic puzzles. Sudoku asks you to place the digits 1 to 9 so that no row, column or box repeats, Minesweeper turns the numbers around each square into a map of hidden mines, and in Lights Out every press also flips the neighbouring lights.
About logic puzzles
Word Guess brings deduction to words, using green and yellow hints to narrow down a five-letter answer in six tries. Sudoku creates a fresh grid every time on four difficulties, with pencil marks for noting candidates, and Lights Out grows from 3x3 boards to 7x7 grids. None of them has a countdown, so you can think for as long as you like, and all four work on phones and tablets.
