Winning Poker Network Logo

The Winning Poker Network, including America’s Cardroom and Black Chip Poker, is set to run its next Online Super Series Cub3d, beginning on Sunday, Aug. 1. The series boasts a total of $20 million in guaranteed prizes. The action will run until Aug. 30 and will feature a variety of game types.

OSS Series

OSS Cub3d Overview

Blue Info BTN

The series takes place over four weeks, and it will feature more than 240 wonderful, action-packed events. As is typical for OSS Cub3d, and the reason for its name, there are actually three separate series.

The MOSS (Mini Online Super Series) takes place first, from Aug. 1 to 9, and it consists of 52 events with buyins between $2 + $0.20 and $50 + $5. It's intended for those with limited funds, which is why the buyins are a bit lower than in the other portions of the OSS Cub3d.

The OSS runs from Aug. 9 to 23. It's the largest portion of the series with more than 130 tourneys to choose from. Buyins range from $15 + $1.50 to $1,000 + $50, and it's thus appropriate for people with a wide range of bankroll levels.

The BOSS (Bigger Online Super Series) takes place from Aug. 23 to Aug. 30 and contains 50+ MTTs. The buyins for this sub-series are a bit higher than the others, from $100 + $4.50 to $2,500 + $150. It's therefore perfect for high-rollers looking for contests that reflect the kind of action they're accustomed to.

Confusingly, some of the events are separated into low, medium, and high versions. For instance, OSS #3L costs $22 to enter while OSS #3M and OSS #3H, which occur on the same day, are priced at $66 and $160 respectively. Therefore, there are actually more series events than you might think by looking at the numbers attached to these events.

A Diverse Schedule and Wide Range of Games


In addition to having a broad menu of buyin levels to choose from, the OSS Cube3d is also notable for the variety of types of poker offered. Though most of the tourneys are for the ever-present NL Hold'em, there are some PLO, PLO8, and 7 Card Stud Hi-Lo contests too. Hypers, Progressive Knockouts, and other structures are present within the schedule.

With hundreds of tournaments on the OSS Cub3d roster, it's virtually impossible for any single individual to enter them all. Therefore, you will have to look carefully in the poker lobby and select those that interest you the most. Nevertheless, there are a few major events that you may wish to keep your eye on.

MOSS Main Event

On Saturday, Aug. 7 at 2:00 p.m. ET, the MOSS Main Event (#20H on the schedule) will begin. The MOSS Main offers a chance to win a share of $500,000 guaranteed for a buyin of just $50 + $5. This event will be in PKO format where everyone has a bounty on his or her head, but the winner of each bounty only wins half of it outright with the other half added to their own head.

The MOSS Main Event plays down until everyone is in the money. Then, the survivors reconvene the following day at 3:05 p.m. to play out the rest of the tournament.

OSS Main Event

The OSS Main Event (OSS #77) is priced at $600 + $30 and carries a $1 million guarantee. It kicks off on Sunday, Aug. 22 at 1:00 p.m. After the tourney reaches the in-the-money stage, play halts for the day. The remaining competitors then regather the next day at 3:05 p.m. and play until the tourney draws to its conclusion.

BOSS Main Event

The BOSS Main Event (BOSS #39) comes with a $1,000,000 guarantee, just like the OSS Main Event does. However, the BOSS Main costs $2,500 + $150 to join, which should make for a relatively small field and tough competition. The BOSS Main Event starts Sunday, Aug. 29 at 1:00 p.m., and the first day runs until it's in the money. The tournament recommences the subsequent day at 1:05 p.m. and plays until it's over.

Multi-Flight Tourneys

There are three multi-flight tournaments this time around in the OSS Cub3d. They are BOSS events #45, #46, and #47. BOSS #45 has a buyin of $600 + $30 and a guarantee of $2.5 million. BOSS #46 costs $200 + $15 to register for with a guarantee of $1,000,000, and it's a progressive knockout event. BOSS #47 has a reasonable buyin of just $15 + $1.50 and a $250,000 guaranteed prize pool.

There are multiple starting flights for these tournaments throughout the series. Each flight halts play when a certain percentage of the field remains. Those who make it through their starting flights then proceed on to Day 2 on Monday, Aug. 30 at 1:05 p.m. when the three tournaments will continue until there's only one player remaining. You can join multiple starting flights until you earn your spot in Day 2.
