Sudoku
The classic number puzzle: fill the grid so every digit appears once per row, column and box. Pure logical thinking — guessing is never needed.
All free brain games
BreinPlezier offers three games that each exercise your brain in their own way: sudoku for logic, mahjong for overview and memory, and word searches for language. Everything is free, without an account and without time pressure — pick whatever appeals to you today.
Choose your game
Mahjong
Find pairs of matching tiles and clear the board layer by layer. Trains your visual overview and planning, at a calm pace.
Word search
Find the hidden words in the letter grid, with topics from animals to countries. Good for your vocabulary and concentration.
A fresh challenge every day
Every game has a daily variant: one puzzle per day, the same for everyone, with a streak that tracks how many days in a row you join in. Many visitors make it a fixed moment — with their coffee or after dinner.
