Online tournament series are the peak events of the poker calendar: concentrated traffic, increased guarantees, extended structures, and a chance to win a five- or even six-figure sum on a single correct decision at the final table. In 2026 the biggest PokerStars and GGPoker series collectively guarantee over $400 million in prize pools per year, plus another $50–80 million is added by Winamax, WPT Global, WPN, and other networks.
For a regular MTT player, proper preparation for the series and smart bankroll distribution within the series often determine the annual result. In this article — an overview of the main 2026 series, their structures and specifics, plus a practical preparation guide.
What Poker Series Are and Why Play Them
A series is a package of online tournaments unified by a shared schedule, theme, and reward system (Player of the Series, overall leaderboards, leagues, tickets to flagship events). Series last from 1 week to 30 days, and within them anywhere from 50 to 700 separate tournaments are played.
The main reasons to play series as a regular:
- Inflated guarantees. Guaranteed prize pools are often 15–30% higher than regular values, which increases your expected result for the same number of tournaments.
- Overlay at low buy-ins. If the room does not gather enough entries before start, the guarantee is covered out of the room’s pocket — that’s free money that goes into the prize pool.
- Concentrated amateur traffic. Series attract recreational players, and a regular’s share in a Main Event pool is on average 15–25% (versus 35–45% in regular Sunday majors).
- Satellites and coupons. You can qualify for major high-roller events through satellites from $1, which radically expands the available buy-in range.
- Image trophies. A win in a PokerStars series tournament (SCOOP plate, WCOOP ring) is a strong image and psychological boost that helps many believe in their own potential.
The Main Series of 2026
The 2026 tournament calendars settled in after the industry’s 2024–2025 consolidation. PokerStars and GGPoker split leadership by total prize pool; Winamax dominates the franco-European market; WPT Global has cemented its position as the third global player.
PokerStars — WCOOP, SCOOP, MicroMillions
The World Championship of Online Poker (WCOOP) runs in September, lasts 25 days, and the 2026 guarantee is $100 million. SCOOP (Spring Championship of Online Poker) runs in May, lasts 22 days, with a $90 million guarantee. MicroMillions is oriented to $1–$22 buy-ins, runs in February and August, with a guarantee of around $8 million.
Features of PokerStars series: a clear three-tier structure (Low / Medium / High), conservative starting stacks of 50,000 chips, slow blinds (12-minute levels), most tournaments are Re-entry until late reg closes.
GGPoker — GGSF, GGMasters Festival, WSOP Online
GGPoker Super Festival (GGSF) is GG’s flagship series, runs twice a year (March and August), lasts 28 days, with a 2026 guarantee of $120 million. GGMasters Festival is a weekly series with a $20 million guarantee. WSOP Online (August — September) is the biggest series with bracelets, total guarantee $200+ million.
Features of GG series: a wide choice of formats (Mystery Bounty, PKO, Flip & Go), aggressive structures compared to Stars (10-minute levels), strong emphasis on bounty tournaments and knockout formats. Mystery Bounty with top prizes up to $1,000,000 in a single box is the main marketing hook of the 2026 series.
Winamax — SISMIX and Winamax Series
Winamax Series runs three times a year (January, April, October), lasts 12–15 days, guarantee about €15 million. SISMIX is Winamax’s main live-online event with a guaranteed €1,000,000 main event.
Features: Winamax series are oriented to the French and Spanish markets but are open to most other European countries and Latin American players. Structures are slow (15-minute levels in the Main Event), low rake, signature formats Expresso (Spin & Go analogue) and Bounty Builder.
WPT Global Online Series
WPT Global Online Series runs four times a year, lasts 14–18 days, guarantee around $25 million per season. The series uses the same Fish Buffet loyalty case program as GGPoker.
Features: tournaments with billed seats guaranteed for live WPT Championship stages, powerful satellites to $10,000+ live events, emphasis on the PKO format with progressive bonuses for knockouts.
WPN, partypoker, CoinPoker and Others
The Winning Poker Network runs the Online Super Series (OSS) six times a year — each with $8–$15 million guaranteed, oriented to the American market and Latin America. Partypoker (after merging with MPN) runs Powerfest twice a year, guarantee about $20 million. CoinPoker launched its crypto series CryptoMillions in 2024 with the equivalent of a $5 million guarantee, settled in USDT and CHP.

Series Preparation — Bankroll and Schedule
Without a separate bankroll plan, participation in a series quickly turns into financial stress. A good approach is to allocate a separate “series bank” that does not overlap with the regular cash bankroll.
- Define your target average buy-in for the series. For example, $33 for a mid-range MTT regular, $109 for a confident reg, or $215 for a regular at the average stake.
- Multiply by 100 — that’s the minimum series bank. For a series with a $33 target it’s $3,300, for $109 it’s $10,900.
- Plan the schedule: 4–6 tournaments per day for a regular with a background job, 10–15 tournaments for a full-time grinder. Tournaments with a deep stack and slow levels (Main Event Day 1) place at the start of the evening, so you’re fresh for the late stages.
- Reserve 1–2 “off” days in the middle of the series for game review, rest, and a medical check — a non-stop two-week marathon leads to a 20–30% winrate drop.
- Start playing Main Event satellites 2–3 weeks before the start date — that gives the resource to qualify across several satellite entries and a calm arrival without last-chance pressure.
Structures: PKO, Mystery Bounty, Regular Tournaments
Modern series include four main structures, and strategy in each differs substantially:
- Regular (Freezeout, Re-entry). The prize pool is distributed by places; classic strategy — stack play, push-fold on the bubble, ICM at the final table.
- PKO (Progressive Knockout). Half of the buy-in goes to the knockout pool: for every player you eliminate you receive part of their bounty, and half is added to your own head. Strategy — increased aggression with bigger stacks against shorter ones, plus the value of blockers against a large bounty stack.
- Mystery Bounty. After a certain stage, eliminated players pull “blind” bonuses (Mystery Boxes), one of which usually contains the maximum prize ($100K — $1M in flagships). Strategy changes dramatically at the Mystery opening stage: knockout profitability rises sharply, and push-fold play becomes more aggressive.
- Sub-Series and Flip & Go formats. Short tournaments (Flip & Go GG, Spin to Win Stars) that let you quickly accumulate a Main Event buy-in or simply rack up activity for loyalty level.
Analyzing Series Results
Without structured analysis, a series turns into a random set of sessions. The minimum of what needs to be done after a series:
- Aggregate ROI by format: calculate separately for regular MTTs, PKO, Mystery Bounty, Hyper tournaments. For most regulars the result varies significantly by structure — that’s a signal of where to specialize in the next series.
- Average finish and distribution. If you bust before the average distance in 70% of tournaments — it’s a signal to work on preflop ranges and adaptation to early play with big stacks.
- Final tables and places 1–3. Any regular should review all their final tables: top-3 decisions by EV, verification through an ICM calculator, line analysis with a coach or in a group.
- List of fish nicknames. The pool of recreational players spotted at the tables and accumulated through the series — a separate value for future hunting in regular tournaments after the series.
Satellite Strategy in Major Series
Satellites are tournaments with a small buy-in and seats in a major tournament as prizes. Through satellites you can qualify for a WCOOP or GGSF Main Event by paying $20–$50 instead of $10,300. This is the main growth tool for a low-buy-in regular.
The structure of satellites in 2026 split into three formats: classic Step satellites (the winner moves on or chooses cash), multi-winner satellites with N seats (for example, 1 of 10 wins a Main Event ticket), and Last-chance satellites with a turbo structure 1–2 hours before the Main Event.
The base strategy of satellites differs from regular MTTs. At the satellite bubble (when N+1 players remain for N seats) ICM pressure reaches extreme values: you have to fold even hands of QQ level against a short stack, because the cost of even the slightest risk is disproportionate to the zero upside from extra chips. After the bubble you already have a ticket — playing for table domination makes no sense. This feature leads to gigantic mismatches in matches: recreational players regularly call with marginal hands on the satellite bubble, losing 100% of their seat equity.
How Much to Play Satellites
A realistic satellite budget — 5–10% of the series bank. For a WCOOP/GGSF Main Event with a $10,300 buy-in, qualifying through satellites costs an average of $400–$800 at a 30–50% ROI (this is a very high hourly rate, but the variance is huge — most attempts end without a ticket).
Regional Series and Local Online Championships
In addition to global events, smaller regional series exist that often give the best value edge for a regular: fewer sharks, a higher share of recreationals, smaller but still significant guarantees.
- PokerStars Latin America (LATAM Series) — concentrated on Brazilian, Argentinian, and Colombian traffic, guarantee around $5 million, Main Event buy-ins $530–$1,050.
- PokerStars EU Spring/Fall Series — separate series on eu-domains for French, Italian, Spanish, and Portuguese players, without Americans or Asians.
- partypoker (Bwin Asia, Bwin EU) — regional mini-series with $2–$5 million guarantees.
- WPN Venom — a separate mega-event with a $10 million guarantee and a $2,650 buy-in several times a year.
- IDNPoker Asian Poker Series — an Asian series with a $1.5 million guarantee, buy-ins $20–$300, predominantly Indonesian, Malaysian, and Thai traffic with a high share of fish.
When a Series Is Not Worth Joining
Not every series is an automatic opportunity. Cases where you should skip or sharply cut participation:
- The series consists predominantly of tournaments with deep stacks and a slow structure, while you specialize in Hyper Turbo — your edge doesn’t realize.
- Series buy-ins exceed your standard level by 3+ times: a series is not the place for a shot-take because the variance is gigantic.
- You have just come out of a major downswing — a series with high expected variance will worsen your psychological state.
- Your main income depends on regular cash: switching to MTT series mode for 2–3 weeks will break your rhythm and lower the overall annual result.
Leaderboards and Player of the Series
Beyond the prize pools of individual tournaments, the 2026 series offer parallel reward systems: leaderboards by series points, Player of the Series (POTS) rankings, plus mini-challenges within series. This is an additional source of overhead profit for a regular who spends a large volume of buy-ins on the series.
PokerStars POTS at WCOOP/SCOOP gives a total $50,000–$100,000 in the leaderboard prize pool: first place gets $25,000–$50,000 in cash plus a trophy, prize places down to 100 are on a descending scale. To realistically contend for the top 5, you usually need to play 100+ series tournaments and consistently cash in the ITM (in the money) zone.
The GGPoker GGSF Leaderboard works on similar logic but adds additional sectional leaderboards (Low Stakes Leaderboard, PKO Leaderboard, Mystery Bounty Leaderboard). This lowers the entry threshold: a low-buy-in professional realistically competes for top-3 in the Low Stakes Leaderboard and can grab $5,000–$10,000 in cash.
Strategic impact of the leaderboard: if you are already deep in the points rating, it makes sense to play slightly wider and more actively on bubbles. If you are an outsider — play purely on each tournament’s prize pool, without regard for the points. The main mistake of mid-level regulars is trying to “stretch” to the leaderboard payout zone with forced buy-ins in the last 2–3 days of the series. This almost always gives negative EV.
Quality series analysis is impossible without a full hand database — especially for hands where you participated only up to the flop or were a side-show by equity. Hand history mining from final tables of the biggest series, available through a service, plus your own hand database in a tracker, gives the full picture: how a TOP-100 GGSF level player differs from you in specific spots, and what exactly needs to be tightened up before the next WCOOP.
