Why Sudoku works

The habit is already there. Millions solve Sudoku every day. Give them a better place to play it.

Sessions that last. 6+ minutes per session on Riddle minigames. Readers sit and finish.

Daily return visits, by design. A fresh puzzle every day plus a leaderboard brings readers back tomorrow.

Leads from players mid-flow. Gate hints or solutions behind an opt-in. Lead forms convert at 28.6% on average.

Sponsored content that earns attention. Brand the theme and the grid. Players spend focused minutes inside it.

How to use Sudoku

Newsletter-gated puzzles.
