Terms of Service
Last updated: August 3, 2026
Introduction
Welcome to TileTally (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at dodouble.com and all associated calculators, guides, and services (collectively, the “Service”).
By accessing or using the Service, you agree to be bound by these Terms. If you disagree with any part of them, please do not use the Service.
Acceptance of Terms
By accessing, browsing, or using TileTally, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated by reference.
We may update these Terms at any time. Your continued use of the Service after changes are posted constitutes acceptance of the revised Terms.
Practical Aids — Confirm House Rules
TileTally’s calculators are practical aids for scoring, probability, timing, brackets, set sizes, and inventory. They apply standard, widely documented rules and combinatorial formulas to the values you enter. Dominoes and tile games vary by region, club, and house rule — scoring conventions in particular differ from table to table — so nothing on the Service is an official ruling for any tournament or league. Before you rely on a result for a scored match, a printed bracket, or a competition, confirm it against the rules your group actually plays by.
Description of Service
TileTally provides free, browser-based calculators and reference resources, including:
- A domino scorekeeper for block and draw play
- A domino set and combination counter
- A domino draw probability calculator
- A tile game timer with an optional increment
- A single-elimination tile tournament bracket generator
- A tile inventory tracker for domino and mahjong sets
- Guides, explainers, and reference content on tile games
All tools are provided free of charge. We may modify, suspend, or discontinue any part of the Service at any time.
Your Responsibilities
When using the Service, you agree to:
- Use the tools in good faith for casual play, family game nights, and club use
- Enter accurate values and check that your inputs describe a valid game state
- Not disrupt, overload, or attempt to compromise the website
- Respect intellectual property rights
You are responsible for exercising your own judgment and for confirming important results before relying on them, especially for scored or competitive play.
Accuracy and Disclaimers
While we aim for correct formulas, we cannot guarantee that every calculation is error-free or suited to your house rules. Results are estimates based on standard methods and the figures you provide, and are rounded for display. TileTally makes no warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, or non-infringement.
Intellectual Property
All content on this website — text, graphics, logos, tools, calculators, and software — is the property of TileTally or its content suppliers and is protected by applicable copyright and other laws. You may use the tools for personal and casual purposes; you may not copy, resell, or reverse engineer them, or remove proprietary notices.
Limitation of Liability
In no event shall TileTally or its suppliers be liable for any damages (including, without limitation, a misscored round, a disputed bracket, or other losses) arising out of your use of, or inability to use, the Service, even if we have been advised of the possibility of such damages.
Third-Party Links and Ads
The Service may link to third-party websites and displays third-party advertisements. We do not control and are not responsible for their content, and inclusion of a link or ad is not an endorsement. Your use of any third-party site is at your own risk.
Governing Law
These Terms are governed by and construed in accordance with the laws of the United States, and you submit to the exclusive jurisdiction of the courts located there.
