Terms of Use

Effective: 10 September 2026

Free game access

The game is free to download and free to play. No VIP tier, subscription, paid unlock or in-app purchase is required to access Sudoku gameplay.

Advertising

Advertising supports operation of the game. Forced interstitial advertising is designed for natural breaks and not for interruption of an active Sudoku. Rewarded advertising, where offered, is user-initiated.

Accounts

You are responsible for keeping sign-in credentials secure. Accounts or competitive results may be restricted when there is strong evidence of abuse, automation, tampering or attempts to manipulate rankings.

Competition

Leaderboards and tournaments use server-verified game records, but no online Sudoku competition can guarantee that a player did not consult an external solver. Rankings are a game feature rather than formal certification of skill.

Generated content

Generated puzzles are algorithmically created and validated by the platform. Printable materials are provided for personal use.

Service changes

Features, events, rewards and advertising formats may evolve. The locked product policy is that gameplay remains free unless Umami Solutions explicitly announces a future policy change.
