Terms

DIGIGMA is a personal logic-puzzle service: Sudoku, Killer Sudoku, Binary Puzzle, Futoshiki, Kakuro, and Codebreaker.

Only the newest official puzzle is free without an account. Signed-in Members and Premium members spend server-authoritative DIG to unlock other official, archive, and community puzzles. An unlocked puzzle can be replayed without another charge. A new official puzzle is published every four hours. Assists make a run ineligible for the leaderboard.

A username is public on leaderboards, unique without regard to letter case, and made of letters, numbers, and underscore. Email is not public. Do not choose a name that impersonates others or uses a reserved guest label.

Each published puzzle has its own permanent leaderboard. Grid games rank by time (above the game minimum). Codebreaker ranks by guesses, then time. Guests can appear. Assisted official runs and Premium replays do not rank.

Premium adds a 10 DIG daily grant, assist tools, replay, statistics, up to four priced community creations per UTC day, approved profile-photo upload, and the ability to open a new private conversation for 2 DIG. A free Member has one lifetime priced community-creation trial.

Premium subscriptions are €3.90 per month, €14.90 per year, or €19.90 per year for Duo with two distinct accounts. Prices include tax. Checkout availability is shown before purchase. Subscriptions already in place renew at their existing price. Previously acquired lifetime Premium access remains honored and is no longer sold.

DIGIGMA does not show advertising, now or later.

The service needs a browser and a network. Brief interruptions can happen for maintenance or incidents. DIGIGMA aims for reasonable availability and does not guarantee uninterrupted uptime.

Profiles

Every new account has a public profile. You can make it private with an explicit choice. A public profile may show your username, library avatar, optional country if you already chose to show it, a short bio, recent completed official plays (game, band, local date — never time, assists, or rank), and a few recent achievements. A private profile is not shown to other visitors.

Comments

Signed-in accounts may leave a single-level comment on a published game page. Guests can read, not post. Do not paste a solution, a finished grid, advertising, or raw links. Comments may be held for review, hidden, or removed. DIGIGMA is not a forum or a chat.

Avatars

Everyone can choose one of DIGIGMA’s two preset avatars. Premium members can submit a JPEG, PNG or WebP image and crop it. The normalized image stays private until an admin or a moderator manually approves it; the current avatar remains visible during review. Refused and replaced images are deleted. DIGIGMA may refuse or remove an avatar that impersonates staff or breaks these terms.

Age for a public profile

A public profile is for people who confirm they are 16 or older. DIGIGMA does not ask for a date of birth. If you are under 16, the public-profile switch stays off. This confirmation is a checkbox when you make the profile public, not an age field on the account.

Block, report, and moderation

You may block another account so you no longer see each other on social surfaces. You may report a username, bio, comment, or avatar. Reports are reviewed by DIGIGMA staff . There is no 24/7 desk. Child-safety reports are treated as priority. We may hide content, reject an avatar, or suspend an account that breaks these terms. We do not auto-ban from a machine score alone.

What is not allowed

Harassment, impersonation (including staff), spam, advertising, pasting solutions or spoilers meant to ruin a play, sexual content involving minors, and any attempt to contact a minor as if they were an adult. Usernames and bios follow the same rules as comments.

Private messages

A Premium member may open a new private conversation for 2 DIG. After the first message, either participant may continue that conversation without another charge. Messages are limited to 1,000 characters. Blocking and reporting controls apply.
