Overlay

What Is Overlay?

Overlay is free money sitting on the table, and spotting it is one of the sharpest edges a tournament player can develop. When a poker room advertises a tournament with a $50,000 guarantee but only collects $38,000 in buy-ins, the room must add the remaining $12,000 from its own funds. That $12,000 is the overlay — extra prize money that every participant benefits from without any additional cost.

Poker rooms set guarantees to attract players, essentially making a promise about the minimum prize pool. Most of the time, popular tournaments easily surpass their guarantees. But when a room is aggressive with its guarantees, launching a new tournament series, or facing heavy competition from rival sites running overlapping events, overlays happen regularly.

For savvy players, overlay hunting is a legitimate strategy. Some grinders specifically track tournament schedules across multiple rooms, looking for events likely to fall short of their guarantees. During major online series when dozens of events run simultaneously, overlays become common because the player pool is spread thin across too many tournaments.

How It Works

Guarantee Calculation: The guarantee is the minimum prize pool the room promises. If total buy-ins (number of entries multiplied by the buy-in amount minus rake) exceed the guarantee, it becomes irrelevant. If they fall short, the room pays the difference.

Spotting Overlay Potential: Late registration periods reveal overlay opportunities. If a tournament with a $20,000 guarantee has only $8,000 in entries with 30 minutes of late registration remaining, a significant overlay is likely. Some tournament lobbies show current entries in real time.

Overlay Frequency: Overlays happen most often during off-peak hours (weekday mornings), during competing series on other sites, in niche formats (PLO, short deck), and in newly launched tournaments that have not yet built a regular player base.

Series Overlays: Major online series like WCOOP, SCOOP, or GG Series frequently produce overlays in their lower-profile events. The flagship tournaments crush their guarantees, but the secondary events on the schedule often fall short.

Example

A poker room announces a Sunday special with a $100,000 guaranteed prize pool and a $109 buy-in ($100 to the pool, $9 rake). For the guarantee to be met, the room needs 1,000 entries. By the time late registration closes, only 780 players have entered, generating $78,000 in player contributions. The room adds $22,000 from its own funds to meet the guarantee. Every player in the field is effectively playing for 28% more prize money than they paid for. Your $100 contribution is now competing for a share of $100,000 rather than $78,000 — an immediate and substantial boost to your expected value.

Where to Find Overlays

Some poker rooms are more prone to overlays than others, often because they set ambitious guarantees to compete for market share.

• GGPoker regularly runs massive guaranteed series where secondary events frequently overlay, especially in mid-week and early-morning time slots.
• PokerStars rarely overlays on its flagship tournaments due to the massive player pool, but niche events and new formats occasionally fall short of guarantees.
• 888poker has been known for generous guarantees that sometimes outpace registration, particularly during their XL series events.
• WPT Global as a newer room with an ambitious tournament schedule, produces frequent overlays as it works to build its player base.

FAQ

How do I find tournaments with overlay?

Monitor tournament lobbies during late registration, especially for events scheduled at off-peak times. Follow poker forums and communities where players share overlay alerts. During major online series, check the less popular events on the schedule — those are the most likely to overlay.

Is overlay hunting a viable strategy?

As a supplementary strategy, absolutely. You should not enter tournaments you would not normally play just because of a potential overlay, but when you are choosing between similar events, factoring in overlay probability is a smart use of your time and bankroll.

Why do poker rooms allow overlays to happen?

Rooms intentionally set ambitious guarantees as marketing tools. The cost of occasional overlays is offset by the long-term benefit of building a reputation for large guaranteed prize pools, which attracts more players over time. It is a calculated business decision, not a mistake.
