Cerebrum: Offline Puzzle Games

Six puzzle games in one app — Sudoku, Crossword, Word Search, Cross Math, Trace and Maze — and one daily ritual to go with them. Every game is free to play, with no subscription wall between you and any of them, and everything works offline, with no wifi and no internet connection needed. No more juggling a sudoku app, a crossword app and a word search app: one download, one streak, one league for all six.

• Cross Math — math games where you place digits to solve a grid of equations
• Trace — draw one continuous path through every cell, hitting the checkpoints in order
