Different puzzles, different kinds of thinking
It helps to mix puzzle types. Sudoku is strict deduction, where every digit follows from the ones already placed. Word puzzles lean on vocabulary and elimination. 2048 and Block Crush are about planning and managing space, and Solitaire is about ordering your moves so you never block yourself.
Start easy and build up
Sudoku on Easy gives around 37 starting numbers and only needs simple techniques, while Hard starts with about 26 and needs methods like naked pairs or pointing pairs. In Solitaire, Draw 1 is the relaxed version and Draw 3 is the classic harder rule set. Move up a level when the easier one starts to feel automatic.
Make it a daily habit
Every game has a Daily Challenge with the same puzzle for every player, which makes an easy routine: one Wordy, one Daily Sudoku, and a game of Solitaire if you have time. The daily puzzles reset at midnight UTC.
