KIDOKU is a local Sudoku game without an in-app account. Classic Levels 1–30 are free. Free Time Attack offers up to three chances, restoring one every 20 minutes; EASY and NORMAL are free, while HARD requires verified Premium. When offered through Google Play, a one-time Premium purchase unlocks Classic Levels 31–60, unlimited Time Attack including HARD, and ad-free play. There is no separate unlimited practice mode.

Google Play handles payment, purchase approval, cancellation and refunds under its policies. Premium access is based on a completed purchase of this product returned by Play Billing. If Play later reports no active purchase, such as after a refund, access is removed. If Play is temporarily unavailable, a recently confirmed purchase may remain available for up to 24 hours in the same app session; reopening offline may require reconnection. No in-app account is created or suspended.

Progress, settings, chances, hints and personal Time Attack records are stored on this device. Clearing app data or uninstalling normally removes local records, although Android backup may restore them. Switching devices does not guarantee recovery of local progress; a valid Premium purchase may be restored through the same Google Play account after verification.

Free Classic play may show occasional ads after a completed level when production ads are enabled and policy requirements are met. Please do not copy, modify or redistribute KIDOKU without permission or interfere with its operation. Third-party open-source licenses are available under About > Licenses. A parent or guardian should supervise children's purchases; the in-app addition check does not prove adulthood or replace Google Play approval. Contact PINWORLD at the address above for support.
