LinkedIn adds Mini Sudoku to keep users engaged beyond professional networking

LinkedIn has found a unique way to boost daily engagement and strengthen user retention by adding a quick, brain-teasing puzzle to its platform. The professional networking site has introduced Mini Sudoku, its sixth in-app game, to keep users coming back to the app.

The new puzzle is a scaled-down version of the classic Sudoku, developed in collaboration with Japanese puzzle publisher Nikoli and three-time World Sudoku Champion Thomas Snyder. Instead of the standard 9×9 grid, Mini Sudoku uses a 6×6 format that can be completed in just two to three minutes. This shorter format is aimed at busy professionals looking for a brief mental break without getting distracted from work.
