OwnersBox is a DFS platform that offers players several unique game formats. It’s best known for its dedication to weekly fantasy sports, offering week-long contests for the NFL, NBA, MLB, and NHL. It’s a direct competitor to DraftKings and FanDuel, currently available in 36 states.

This OwnersBox review will show you the ins and outs of the OwnersBox California app and website, telling you how to claim its welcome offer and highlighting its most prominent features. It will also detail how those eager for legal California sports betting can scratch their wagering itch with OwnersBox for the next few years.

The OwnersBox 100% match deposit bonus of up to $500 is one of the best among US DFS platforms. For example, DraftKings DFS California only offers a 20% match up to $500, so you must deposit $2,500 to get the full bonus.

The minimum deposit is just $10 and the turnover rate is at a reasonable 4%, meaning that if you enter a $100 contest, you’ll convert $4 of your OwnersBucks into real money. The turnover rate increases based on your rank.

Apart from the first deposit offer, OwnersBox California has a no deposit signup bonus that grants you two $10 entries, one for each of the OwnersBox games called Lightning Lineups and SuperFlex DFS. To unlock this offer, you must use the promo code that will be sent to the email address you used to create your account.

Where Is OwnersBox Available?

OwnersBox is available in 36 states, Washington DC, and Canada.

OwnersBox is not available in Arizona, Connecticut, Delaware, Hawaii, Idaho, Indiana, Iowa, Louisiana, Maine, Michigan, Mississippi, Montana, Nevada, and Washington. Meanwhile, New Hampshire, Maryland, Ohio, and Tennessee players can only play the SuperFlex DFS game, not Lightning Lineups. 

Note that the age restriction may differ between states. California requires DFS participants to be at least 18 years old.

OwnersBox California

California isn’t exactly friendly toward gambling, as it doesn’t permit commercial casinos, sports betting, or any type of online gambling. However, since there are no specific laws banning DFS contests, players from CA are free to participate in them.

OwnersBox Florida

Florida has a similar take on daily fantasy sports as California. DFS sites are technically not legal, but without laws that expressly prohibit them, players are free to enter real-money contests on OwnersBox and other DFS platforms.

OwnersBox New York

The state of New York has recently opened up to online gambling, legalizing online sports betting and aiming to do the same with online casinos in early 2023. As for DFS, New York was one of the first states to pass fantasy sports regulations in 2016.

OwnersBox Texas

Even though the Texas Attorney General claimed DFS was gambling as far back as 2016, DFS platforms continued to operate unhindered in the Lone Star State.

OwnersBox CA App Review

OwnersBox is available on desktop, while mobile players can use its proprietary apps. You can download the apps on Google Play and App Store, where you can also view their specs and read user reviews.

Navigation and Design

Both the OwnersBox app and the desktop site feature a well-thought-out design, making it easy to find and enter contests and keep track of your players. The homepage lists all featured competitions and details regarding promotions and new features. 

The app and website are in dark mode by default, and the black and gray tones go well in contrast with a blue highlighter, giving the whole platform a recognizable look.

Fantasy Sports and Games on OwnersBox

The OwnersBox DFS app features NFL, NBA, MLB, and NHL contests. These are the four major American sports, but we’d sure like to see the list expand to golf, soccer, and other sports, as seen on DraftKings and FanDuel DFS California.

OwnersBox features several unique game formats, such as SuperFlex DFS, Lightning Lineups, and Weekly Bracket, which we’ll explain in more detail later.

The app pioneered weekly fantasy sports, which immediately set it apart from the competition. While daily fantasy sports are still available, most players come to OwnersBox to try WFS games because they are entertaining and require a more strategic approach.

OwnersBox App Compatibility and Sign-Up Guide

As soon as you enter the OwnersBox DFS website, you’ll find buttons leading to Google Play and the App Store, where you can easily download the app to your Android or iOS device.

How to Download the OwnersBox App on Android

  1. Go to Google Play and type in “OwnersBox” or follow the link on the operator’s homepage. Canadian players will find a separate button to download the APK file directly.
  2. Tap Install and wait for the app to download and install.
  3. Load the app, log in, and start playing.

How to Download the OwnersBox App on iOS

  1. Go to the App Store and search for OwnersBox or follow the link provided at the operator’s website.
  2. Tap Get, and the app will be installed on your iPhone or iPad.
  3. Power up the app, type in your credentials and start creating your fantasy lineup.

OwnersBox Deposits and Withdrawals

Banking on OwnersBox California could use a few extra options. The operator only accepts a couple of methods, which might bother players who are used to e-wallets and other alternatives for online payment.


California players can do simple and safe online banking (ACH) and transfer their funds directly from a bank account. The other option is the credit card deposit, accepting Visa, Mastercard, American Express, and Discover. The minimum deposit is $10 and the maximum is $1,000, with all deposits processed instantly and without fees.

While depositing with a credit card is convenient, you should think twice before doing it. Cash advance interest rates can be pretty high, and card payments are sometimes declined when made to gambling-related sites, especially in states where gambling is not adequately regulated.


You can withdraw the winnings from your OwnersBox account via online banking and physical checks sent by mail. Online banking withdrawals are typically processed within five days, while checks can take longer.

Types of DFS Contests at OwnersBox

Here’s more about the different games and contests available on OwnersBox.

Daily Salary Cap

It’s as simple as it sounds: try to build a lineup for the day while staying under the salary cap.

Weekly Tournaments

The goal is to construct a 10-player lineup for a tournament that lasts one week, with the winners determined by the accumulated number of fantasy points. Multiple players can finish “in the money,” and the prize pool size depends on the tournament type, the number of participants, and the entry fees.

SuperFlex DFS

SuperFlex DFS introduces a special roster slot that allows the addition of a second quarterback or an extra running back, receiver, or tight end. It is exclusive to daily fantasy football.

Lightning Lineups

The Lightning Lineups game generates a player lineup randomly and allows you to spin indefinitely until you find a lineup you like. Once satisfied with the lineup, choose an entry amount and watch your players perform.

Weekly Bracket (H2H)

Weekly Bracket is a head-to-head knockout tournament game that two to sixteen teams can play for one to four weeks.

What OwnersBox Gets Right

OwnersBox might not be on the level of DraftKings and FanDuel yet, but there are several things it does right, even better than its main competitors.

Weekly Fantasy Sports

The weekly format on OwnersBox works pretty well and adds a new dimension to fantasy sports, requiring a more thought-out approach. While some games and contests are unique, they are not far from what you can see on other DFS platforms, so you don’t have to be concerned about a steep learning curve.

Great Design and User Experience

Both the OwnersBox app and website are defined by their sleek design and effortless navigation. It’s effortless to find and enter contests, read through the news feed, and keep track of your players.

Extra Content

OwnersBox has shown great efforts in creating community through content. The operator’s content team is present on all major platforms from Discord to TikTok, and their YouTube channel is full of dedicated podcasts for each of the four major leagues.

OwnersBox California Overall Review

Despite existing for only a couple of years, OwnersBox has firmly positioned itself on the map of the best DFS apps in California and beyond. It’s currently cornering the market on weekly fantasy sports while adding new and exciting game modes from time to time. New players are in for a treat, as there’s both a no-deposit offer and a deposit bonus worth up to $500 in site credit.

A couple of areas in which OwnersBox could improve are the number of sports and banking methods. We would like to see more than the four major leagues. OwnersBox is behind the competition in this regard, as sites like DraftKings and FanDuel added golf, soccer, MMA, NASCAR, and more. Meanwhile, accepting e-wallets and other payment alternatives might smooth out the cashiering experience.
