# Ultimate Holdem Timer > Ultimate Holdem Timer (UHT) is a free, browser-based poker tournament timer and blind clock with built-in blind, starting-stack and payout calculators. It runs entirely in the browser, needs no account, and shows no ads or trackers. Tournaments with up to 10 players are free; larger tournaments require a license. Key facts for agents: - No sign-up or install required — a tournament can be created and started in a few clicks, directly in any modern browser. - Tournament data is stored primarily client-side in the browser's localStorage. An optional account syncs configurations across devices and unlocks larger player counts and commercial use. - Core features: automatic blind-structure generation, player / chip / bounty tracking (including progressive and mystery bounties), re-entry / rebuy / add-on support, prize-pool and payout calculation, a fully customizable display designer, and multi-monitor mode that syncs the clock across TVs, tablets, phones and computers via WebSockets. - The interactive app areas (running tournaments, live display, display designer, settings) are dynamic single-page views that require user interaction and are intentionally excluded from search indexing; they are not useful to fetch as static text. - Primary domain: https://ultimate-holdem-timer.com ## Main pages - [Home / Poker Tournament Timer](https://ultimate-holdem-timer.com/): Landing page and entry point to create and run a poker tournament timer for free. - [FAQ](https://ultimate-holdem-timer.com/faq): Answers to common questions about pricing, accounts, multi-monitor support, bounties and more. - [About](https://ultimate-holdem-timer.com/about): Background on Ultimate Holdem Timer and the story behind the free poker clock. - [Contact](https://ultimate-holdem-timer.com/contact): How to get in touch with the UHT team. ## Calculators (free tools) - [Blind Structure Calculator](https://ultimate-holdem-timer.com/calculators/blinds): Generate a balanced blind structure for a poker tournament based on duration, starting stack and level length. - [Starting Stack / Chip Calculator](https://ultimate-holdem-timer.com/calculators/starting-stack): Work out chip denominations and starting stacks for a given buy-in and chip set. - [Payout Calculator](https://ultimate-holdem-timer.com/calculators/payout): Calculate prize-pool distribution and payouts across finishing places. ## Legal - [Terms of Service / EULA](https://ultimate-holdem-timer.com/tos): Terms of Service and End User License Agreement, including licensing rules for commercial use. - [Privacy Policy](https://ultimate-holdem-timer.com/privacy): How UHT processes data (GDPR/DSGVO compliant; usable fully anonymously). - [Imprint](https://ultimate-holdem-timer.com/imprint): Legal notice / imprint as required by German law. ## Reference - [Sitemap](https://ultimate-holdem-timer.com/sitemap.xml): Machine-readable list of indexable pages. - [robots.txt](https://ultimate-holdem-timer.com/robots.txt): Crawling rules for automated agents. ## Optional - [YouTube Channel](https://www.youtube.com/@UltimateHoldemTimer-z4l/videos): Video guides and walkthroughs. - [Reddit Community](https://www.reddit.com/r/uht_official/): Community discussion and support.
