Mosaico City

Terms and rules

Last updated: 3 November 2026

1. Who runs the game

The game Mosaico City at mosaico.games/city (the “Game”) is run by:

JGS – PROSOFT Kamil Wojtyła
ul. Józefa Braka 29C lok. 2, 43-344 Bielsko-Biała, Poland
Tax ID (NIP) 9372562957, REGON 361984407
e-mail: hello@mosaico.games

These terms set out the rules for using the Game. By using the Game you accept them. The Game is free, with no ads and no paid extras.

2. Technical requirements

You need a device with internet access and an up-to-date browser (e.g. Chrome, Safari, Firefox, Edge) with JavaScript and cookies enabled. The Game works on computers, tablets and phones.

3. How the game works

Every day a new city board with 10 tasks appears, the same for all players. In each task you collect all the goals in as few steps as possible. You can move on the sidewalk, road, rail, metro, ship, ferry and tunnel, and switch between them at transfer points. Each move and each switch is one step; crossing one tile on the sidewalk takes two steps.

4. Board time, points and rankings

• Each board is active for 24 hours, at the same time for everyone: from 00:00 to 24:00 UTC.
• Scores can be earned and improved only while the board is active. Solutions sent after it closes do not count.
• The shortest possible route scores 100 points; each extra step costs 3 points; a solved task is worth at least 10 points, an unsolved one 0.
• Your best attempt sent while the board was active counts. A whole board is worth up to 1000 points.
• Players see their points for a task and the length of the shortest route right after solving it. The daily, weekly and monthly rankings are shown live and can change until the board closes. The shortest routes are published after the board closes. Players with the same score share a place. See rankings.

5. Player account

• No sign-up is needed. When you solve your first task, the Game creates a guest account with a random player name and avatar and remembers it in a browser cookie.
• You can change your player name in your profile once a day. Names: 3–20 characters (English letters, digits, “-” and “_”); they must not be offensive or vulgar, or impersonate other people or brands.
• Your account lives in your browser. You can move it to another device with a one-time code from your profile (“Connect another device”), valid for 10 minutes. Don’t share the code with anyone.
• Clearing browser data on a device that isn’t connected to another one means losing access to the account and its scores. We are not responsible for such a loss.

6. Fair play and prohibited conduct

In particular, you must not:

• use programs, scripts or bots that find or send routes for you;
• exploit bugs in the Game to gain points or unauthorised access;
• create accounts to manipulate the rankings;
• overload or attack the server;
• use player names that break the law, common decency or the rights of others.

If these rules are broken, we may replace the player name with a random one, exclude the account from the rankings or block it. The server checks every route — routes impossible on the board are rejected.

7. Copyright

The Game, boards, graphics, texts and software belong to JGS – PROSOFT Kamil Wojtyła or are used under licence. Avatar icons come from Microsoft Fluent Emoji (MIT licence, licence text). Without our consent you may not copy or distribute parts of the Game beyond normal use (such as sharing links and screenshots).

8. Availability and changes

We do our best to keep the Game running, but we can’t guarantee it — technical breaks, outages or maintenance may happen. The Game evolves: we may change boards, task types, design and scoring rules. Changes don’t recalculate scores from days that have already ended.

9. Complaints and contact

Send feedback and complaints about the Game to hello@mosaico.games, with your player name and a description of the problem. We reply within 14 days.

10. Stopping use

You can stop using the Game at any time and ask us to delete your account and scores (see the privacy policy). We may shut the Game down, announcing it on the site at least 14 days in advance.

11. Changes to these terms and governing law

We will announce changes to these terms on this page at least 7 days before they take effect, unless the change is required by law or for security. These terms are governed by Polish law. Nothing in them limits the rights consumers have under mandatory law, including the law of their country of residence.

The Polish version is the binding one; this English version says the same.
