About Us

Mobile Online Sportsbooks is a research and comparison site built for US bettors trying to work out which mobile sportsbook actually deserves their time and their money. This page explains what we do, how we put our rankings together, and where the limits of our coverage sit — so you can weigh our reviews with the right context.

What we cover on copowersports.com

We focus specifically on mobile online sportsbooks: the apps and mobile-optimized sites that let US bettors wager on football, basketball, baseball, hockey, soccer, golf, esports and more from a phone or tablet. Our reviews look at the whole experience — sign-up and verification, deposit and withdrawal options, odds and market depth, live betting, promotions, and how each site behaves when something goes wrong. We're not a sportsbook, we don't accept wagers, and we have no stake in which platform a reader ultimately chooses.

Who this site is for

Our readers land here for different reasons. Some already have an account somewhere and want to check whether the odds, limits or banking options stack up against alternatives. Others are comparing sportsbook apps for the first time and want a plain-English rundown of what to expect before they hand over any personal or financial details. A smaller group is specifically looking at offshore sportsbooks after being restricted or limited elsewhere, and wants to understand what that actually means in practice. We try to write for all of these readers without assuming any of them are beginners.

How we research and rank sportsbooks

Every sportsbook featured on copowersports.com is assessed against the same set of practical criteria, applied consistently across the board:

• Odds and pricing — how competitive the lines are across major US sports and markets
• Range of sports and markets — coverage of NFL, NBA, MLB, NHL, NCAA football and basketball, soccer, golf and other markets, including racebook options where offered
• Mobile experience — how the app or mobile site performs for placing bets, cashing out and following live action
• Banking — the deposit and withdrawal methods on offer, including crypto, along with stated processing times and any fees
• Promotions — welcome offers and ongoing promotions, always read alongside their rollover requirements, minimum odds and time limits
• Support and reliability — how contactable and consistent a sportsbook's customer service actually is

Ratings shown next to each featured sportsbook — for example Lucky Rebel, Bovada, BetOnline and the others in our rankings — are editorial scores based on this research, not customer-submitted reviews. Where a sportsbook advertises a bonus, such as Lucky Rebel's 125% match up to $1,250 plus a free bet, or BetNow's 125% offer up to $2,500, we always try to note the rollover requirements and eligibility conditions that come attached, because the headline number alone rarely tells the full story.

Some sportsbooks that appear on this site pay us a commission if a reader signs up through our links. That relationship never decides where a sportsbook lands in our rankings — position is based on our research criteria, not on who pays the most. We'd rather lose a placement than mislead a reader.

Offshore sportsbooks: what "about" really means here

A large part of what we cover involves offshore sportsbooks — platforms licensed outside the US, typically in jurisdictions like Curaçao, Panama or Costa Rica. It's important to be direct about what that means: these sites operate in a legal grey area for US bettors. They are not licensed or regulated by any US state gaming authority, and the consumer protections that come with a regulated domestic sportsbook — such as segregated player funds or a formal dispute resolution process through a state regulator — do not apply. If an offshore sportsbook delays a payout or handles a dispute poorly, a US bettor generally has far less recourse than they would with a state-licensed operator.

We describe these sites honestly rather than dressing them up as fully legal or regulated. Readers should check their own state's laws before using any offshore or online sportsbook, since legality varies significantly across the US.

Why our reviews exist

The sports betting market is crowded, and new betting sites launch constantly with aggressive-sounding welcome offers. Some are well-run and pay out promptly; others are not. We exist to cut through that by digging into the details that matter — verification requirements, withdrawal limits, actual odds quality, and how a sportsbook treats its customers once the sign-up bonus is claimed — rather than repeating whatever marketing copy a sportsbook publishes about itself.

Responsible gambling comes first

Sports betting carries real financial risk, and nothing on this site should be read as a way to guarantee winnings or replace income. We do not present tips, picks or promotions as sure things, and we don't encourage betting more than someone can comfortably afford to lose. If gambling stops being enjoyable or starts to feel like a problem, free and confidential help is available through the National Problem Gambling Helpline at 1-800-GAMBLER. We also maintain a dedicated Responsible Gambling page with tools and resources for readers who want to set limits or take a break. It's worth noting that offshore sportsbooks often provide fewer built-in responsible gambling and self-exclusion tools than regulated US operators, so it's worth checking what's available before signing up anywhere.

Everything on copowersports.com is intended strictly for adults aged 21 and over. We do not create content aimed at, or accessible to, anyone under that age.

A general note on legal and tax information

Any legal or tax information referenced across copowersports.com, including anything about the status of offshore sportsbooks or how gambling winnings may be taxed, is general in nature and not a substitute for professional advice. Betting laws differ by state and change over time, so we'd always recommend checking with a qualified legal or tax professional about your own situation before acting on anything you read here.
