An overlay happens when a tournament's guaranteed prize pool is bigger than the buy-ins collected from the field. The site has to make up the difference out of its own pocket, which means every seat left in that tournament is worth more than what players paid to sit in it. On 888poker, this shows up constantly in satellites: single-table and multi-table qualifiers that feed into the site's WSOP online qualifying program and its 888poker LIVE festivals. The operator has run WSOP satellite qualifying since 2014, and its live stops in Spain and the UK are regularly fed by online satellites, including entries won for as little as 55 euros.
Satellites overlay more often than regular guaranteed tournaments for a simple reason: 888poker sets a guarantee based on expected turnout for a live festival seat or a package, and turnout for a specific satellite on a specific day is harder to predict than turnout for a recurring flagship MTT. When a satellite undersells, the site adds cash or extra seats to cover the guarantee, and that added value gets split among whoever is left in the field.
In a normal guaranteed tournament, overlay just means bigger average payouts. In a satellite, overlay changes the actual math of qualifying: if a $100,000 GTD Main Event satellite pays out 20 seats but only 15 satisfy the buy-in requirement to fill the guarantee, the site adds seats or cash equity to cover the shortfall, and your odds of winning a seat go up without you doing anything differently at the table.
Overlay is only half the story. The other half is when you get in. GTO Wizard ran an ICM (Independent Chip Model) study on late registration and found that a player who registers late into a standard multi-table tournament effectively picks up seat equity worth about 10.9% more than the buy-in, purely from ICM, before playing a single hand. In a satellite with a flat payout structure, where everyone who cashes wins the same prize, like a seat, that effect is much larger: GTO Wizard found the equity boost jumps to roughly 29.76% (source).
This is important to label correctly. It is ICM seat equity, not ROI. It reflects the fact that some of the field has already busted by the time you sit down, so the money that would have gone to those players is now spread across the players still alive, including you. Combine that with an overlay-heavy satellite and you get two separate sources of extra value stacked on top of each other: the site's added money, and the ICM gain from entering after weaker stacks have already been eliminated.
| Format | Late Reg ICM Effect | Why |
|---|---|---|
| Standard MTT | About +10.9% seat equity vs buy-in | Field has thinned, weaker stacks already busted |
| Flat-paying satellite | About +29.76% seat equity vs buy-in | Every cash spot pays the same, so surviving players split more per head |
| PKO (bounty format) | About -14% stack value | Bounties get removed as players bust, which cuts the ICM benefit of waiting |

Not every 888poker tournament rewards late registration. Progressive knockout (PKO) events split the prize pool between a standard payout structure and bounties that get paid out and removed from the pool as players bust. GTO Wizard's analysis shows that where late registration ends with roughly 30 to 35% of the field remaining, the bounty pool has typically shrunk by 40 to 45%, and a starting stack that enters late is worth about 14% less than one that started from hand one. If you're deciding whether to jam in early or wait on an 888poker PKO satellite, the data says get in early and start collecting bounties, not wait.
There are two ways to do this, and they scale very differently.
Manually: open the 888poker lobby, find the satellite you care about, and compare the guaranteed prize pool to (buy-in minus rake) multiplied by current registrations. Refresh that math every few minutes as late reg counts down, since overlay percentage moves constantly as more players register. This works for one tournament at a time, which is fine if you only play one satellite a night. It falls apart once you're running multiple tables across multiple sites, since 888poker alone runs dozens of qualifiers daily, on top of whatever else is open across the other networks you play.
Automated: this is where a scanner earns its keep. Profitmaxxer checks 888poker's lobby, alongside the other networks it covers, every 30 seconds, and calculates the live overlay percentage on every running tournament, including satellites. As of the current tracking window, the scanner has logged $2,819,087 in total overlay across 3,128 separate instances, including $76,585 detected specifically on 888poker, at a running average of roughly $215,000 in overlay found per day across all tracked networks. When a satellite's overlay crosses your minimum threshold, or its late reg window is closing, you get a Telegram alert with the number and the clock, instead of finding out after the fact that you missed it. For a broader rundown of tools built for this exact problem, see Best Tools for Finding Poker Tournament Overlays and the step-by-step method in How to Find Poker Tournament Overlays.
The highest-value spot on 888poker is a satellite that is both overlaid and still open for late registration. You get the site's added money and the ICM bump from entering after part of the field has already busted, in the same tournament. Here is the sequence that captures both:
Overlay totals move daily, so treat any single number as a snapshot rather than a permanent fact. Recent scanning has shown typical daily output across tracked networks of 800-plus overlay alerts and 450-plus late reg alerts, spanning 200-plus unique overlay tournaments and more than $165,000 in overlay value in a single 24-hour period. 888poker satellites are a recurring part of that total, not a one-off event.

| Question | Answer |
|---|---|
| What is an 888poker satellite overlay? | The guaranteed seats or prize pool exceed what the buy-ins collected, so the site adds the difference |
| Does late reg help in satellites? | Yes, about +29.76% ICM seat equity in flat-paying satellites, versus about +10.9% in standard MTTs |
| Does late reg help in PKOs? | No, a late starting stack loses about 14% of its value |
| How do I catch overlay before it disappears? | Manual lobby math for one tournament, or an automated 30-second scanner for everything running at once |
Overlay in 888poker satellites is not rare, and it is not hidden. It is sitting in the lobby, visible to anyone comparing guarantee to buy-ins collected. The players who consistently capture it are the ones checking at the right moment, whether that is a habit of refreshing the lobby or an alert doing the refreshing for them.
