Terms

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

Guests can play puzzles published in the last 24 hours. A free account can start 15 puzzles each UTC day, with 2 hints. A new puzzle is published every four hours. Premium removes those daily limits and adds the solution, replay, and a personal daily grid. Using an assist on the official first run removes that run from the puzzle 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 is optional. It unlocks assist tools, replay of completed puzzles, and personal stats. It is not required to play published puzzles or to appear on a leaderboard.

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 account has a profile. It is private by default. You can make it public 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

You choose an avatar from DIGIGMA’s presets. Image upload is not offered. Free accounts can pick the man or woman look. Full customization is reserved for Premium (Founding Member). DIGIGMA may reject or reset 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 (Anim for day-to-day tone; HQ for hide, reject, and bans). 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

DIGIGMA does not offer a private-message inbox in this version of the service. Do not use comments to exchange personal contact details.
