What a guaranteed prize pool actually means
Understand guaranteed prize pools in poker. Learn how they work, what 'overlay' means, and why they matter for tournament players in the UK.
When you see a poker tournament advertised with a '£5,000 Guaranteed' or '£10,000 GTD' prize pool, it means the organiser has committed to paying out at least that much money, regardless of how many players enter. This is a common feature in live poker events across the UK.
How Guarantees Work
The prize pool is built from player buy-ins. Each player pays a set amount, and a portion of that goes directly into the prize fund, with another part usually taken as a rake or fee by the venue. If the total contributions from players exceed the guarantee, the prize pool simply grows larger. So, a £10,000 guaranteed tournament with enough entries might end up with a £15,000 prize pool, for instance.
Understanding 'Overlay'
This is where guarantees get interesting for players. If a tournament doesn't attract enough entries to meet its advertised guarantee from player contributions alone, the organiser has to make up the difference. This 'top-up' is called an overlay. For example, if a £10,000 guaranteed tournament only generates £8,000 from player buy-ins, the venue adds £2,000 to ensure the £10,000 minimum is paid out.
Overlay is effectively 'free money' for the players, as the prize pool is bigger than what was collected. It represents extra value for everyone who played, as their share of the prize pool is proportionally larger than it would have been otherwise. Spotting potential overlay can be a key part of choosing which tournaments to play, and our trip planner can help you find events that might offer good value.
Why Guarantees Matter to Players
Guarantees offer a level of assurance. You know there's a minimum amount of money to play for, which can make a tournament more appealing, especially for those travelling to play. It removes some of the uncertainty about prize pool size, ensuring the event is worth your time and effort.
For organisers, guarantees are a way to attract players and generate interest. They signal confidence in the tournament's draw and can encourage participation, even if it means risking an overlay.
