WorldWinner vs Skillz: How They Compare

WorldWinner is one company running one catalog. WorldWinner lists more than 30 current titles, including betas, and a single account reaches all of them through the iOS app, the Android app, or web play at web.worldwinner.com. It suits players who want several game types, including licensed brands such as Wheel of Fortune and YAHTZEE, under one balance and one set of rules.

Skillz is a platform, not a single game app. Its parent company describes the Skillz platform as one that helps developers by enabling social competition in their games (Firy Inc. investor release, July 28, 2026). The games themselves are separate apps from outside studios. The App Store lists Tether Studios, LLC as the seller of Solitaire Cube and 21 Blitz, and those listings direct questions about cash tournaments to Skillz support. It suits players who want one specific mobile game and are comfortable installing a separate app for each title.

Both describe their contests as skill-based tournaments with entry fees and posted prizes. On either service an entry fee can be lost, most entrants do not take the top prize, and winnings are never guaranteed. This guide is independent and is not operated by WorldWinner or by Skillz.

Every WorldWinner entry below matches this site's fact sheet (verified 2026-09-18). Every Skillz entry comes from a Skillz, Firy Inc., developer, or App Store page checked on 2026-09-20 and listed in the sources at the end of this page. Terms change, so readers should confirm current details with each company.

WorldWinner's catalog sits in one place: solitaire, card, bingo, word, puzzle, arcade, and sports-themed titles, plus licensed brands including Wheel of Fortune, SCRABBLE Cubes, BOGGLE, YAHTZEE, and Atari Breakout Blitz. WorldWinner publishes rules and, for many titles, point values in its help center, and it runs several tournament formats, including Head-to-Head, Multiplayer, Solo Challenge, Survivor, and JackPOP.

On Skillz, each game is its own product from its own studio. Tether Studios' site lists about 30 games of its own, and Big Run Studios' support page describes the studio as the developer of Blackout Bingo and Skillz as a separate platform that handles the real money side. The App Store listings for Solitaire Cube and 21 Blitz describe Head to Head games and large multiplayer tournaments.

The practical difference is where depth comes from. A single-game app can gather a large audience around one title: the App Store shows about 96,000 ratings for Solitaire Cube and about 95,000 for Blackout Bingo as of 2026-09-20. WorldWinner spreads its players across a wider catalog inside one account. This guide compares three of those Skillz-powered games with their closest WorldWinner titles on separate pages: Solitaire Cube, 21 Blitz, and Blackout Bingo.

WorldWinner states that players never face bots, that opponents are matched by a per-game skill rating, and that matching is handled before an entry is played. The fair play page on this site covers those statements in detail.

Skillz makes a similar public statement. Its fairness page says it will match players only against "real human opponents of equal skill" and adds "No unfair bots, not ever" (skillz.com/fairness, checked 2026-09-20). Its support center says most matching is asynchronous, that both players play the same match with the same conditions, that skill is assessed before a game is played, and that an unmatched game is cancelled and refunded after 7 days. A separate support article says Skillz staff members may appear in live tournaments with a Staff badge, cannot withdraw or profit, and that a player who loses to a staff member is refunded the entry fee. This guide reports both companies' statements as their own and has not audited either matching system.

Skillz has also been the plaintiff in two lawsuits about bots at competing companies. WorldWinner was not a party to either case, and neither case produced a finding about WorldWinner.

Skillz Platform Inc. v. AviaGames Inc. Skillz filed a patent infringement suit on April 5, 2021. On February 9, 2024, a federal jury in San Jose, California found that AviaGames willfully infringed U.S. Patent No. 9,649,564 and awarded $42.9 million, according to Skillz Inc.'s Form 10-Q for the quarter ended September 30, 2024. Reuters reported on February 9, 2024 that Skillz had told the court it uncovered evidence that AviaGames used bots in its cash games, and that AviaGames denied the allegations. The same 10-Q says Skillz and developer Big Run Studios brought a separate federal case in San Francisco for false advertising, copyright infringement, and California unfair competition. Status: the 10-Q reports that on April 13, 2024 the parties settled both cases, with AviaGames agreeing to pay $80.0 million in total in exchange for dismissal. The false advertising claims ended by settlement, not by a verdict.

Skillz Platform Inc. v. Papaya Gaming, Ltd., No. 1:24-cv-01646 (S.D.N.Y.), before Judge Denise Cote. Skillz sued on March 4, 2024 under the Lanham Act's false advertising provision and New York General Business Law Section 349, alleging that Papaya advertised its tournaments as fair and skill-based while using bots. On April 23, 2026 a jury found Papaya liable on both counts and awarded $420 million in damages, with an advisory disgorgement figure of $719 million, according to the court's later opinion. That opinion also states that Papaya stopped using bots near the end of 2023. In the same opinion, dated July 27, 2026, the court rejected Papaya's post-trial motions and awarded $719 million in disgorgement in place of the damages figure, plus attorney's fees for 2024 and 2025 that Firy put at approximately $10 million, and said a separate opinion would address Skillz's request for an injunction. Status: PocketGamer.biz reported on July 28, 2026 that Papaya said it was disappointed and was pursuing "all available options, including appeal." Firy's own release on the same date cautions that the timing and amount of any recovery are uncertain. This guide did not find a public record of an appeal ruling as of 2026-09-20.

Papaya also made claims against Skillz in that case. According to Skillz Inc.'s 10-Q, Papaya filed counterclaims in August 2024 alleging, among other things, that Skillz engaged in false advertising by allowing bots in games on its platform. A court opinion dated February 20, 2026 states that summary judgment was granted to Skillz on Papaya's counterclaims on November 21, 2025, on the ground that Papaya had not offered sufficient evidence of injury. That ruling turned on the injury element. The opinions reviewed for this page do not contain a finding that Skillz used bots.

WorldWinner: the minimum deposit is $5, accepted methods include Visa, Mastercard, American Express, Discover, PayPal, Venmo, and Apple Pay, and WorldWinner charges no deposit fees. The minimum withdrawal is $1.75, withdrawals return to the original deposit method first, card and PayPal withdrawals can take 7 to 10 business days, and checks can take up to 8 weeks. Withdrawing forfeits all Bonus Bucks, and a $3.50 monthly inactivity fee applies once a cash account has gone 6 consecutive months without a login.

Skillz: its support center says deposits are accepted by credit card, PayPal, and Apple Pay. Deposited funds must be played in matches once before they can be withdrawn. Withdrawals up to the total deposited go back to the same payment method, and in the US winnings above that amount are sent by paper check. Skillz tells players to expect withdrawals in 4 to 6 weeks while saying many are processed much more quickly, and it offers Instant and Fast Bank withdrawals that go to a bank account and are, in its words, processed faster. There is a $1.50 charge for any withdrawal under $10.

The bonus mechanics are close to identical. Skillz says bonus cash cannot be withdrawn, is forfeited when a withdrawal is made, and is applied at $0.10 for every $1.00 of entry fee. WorldWinner's Bonus Bucks also apply at $0.10 per $1 of entry fee, cannot be withdrawn, and are forfeited on withdrawal. On either service, a player holding a large bonus balance should read the terms before cashing out.

Skillz's support center lists a $2.00 monthly maintenance fee after 6 months of inactivity, taken from the in-app balance starting with bonus cash, with no fee when the balance is $0, and says Skillz may close an account after 12 months of inactivity.

WorldWinner's terms list six states where cash competitions are not offered: Arkansas, Connecticut, Delaware, Louisiana, South Carolina, and South Dakota. WorldWinner's published list also says card games are not offered for cash in Indiana and Maine, and that Arizona and Florida do not get Progressive, Mega Event, or Fixed Prize Unlimited Entry tournaments.

Skillz's eligibility article (checked 2026-09-20) says cash games are not currently available in AR, CT, DE, LA, and SD, that cash gameplay is not available in ME and IN if playing cards are involved, and that cash matches are not available in dominoes in New Jersey. Skillz's published list does not name South Carolina, which WorldWinner's does. Skillz also requires device location settings to be enabled for cash play.

These are each company's published lists, not legal advice or a conclusion about the law in any state. Both companies check eligibility before a paid entry, and both lists can change. The availability page on this site covers WorldWinner's list state by state.

On Android, neither service relies on Google Play. WorldWinner's Android app is a direct download from its corporate site. Skillz's Android guide says Google Play generally restricts apps that facilitate real-money games, contests, and tournaments, and that some Skillz games are therefore offered through an official direct download or in a browser.

Where Skillz has the edge on published terms: a lower inactivity charge ($2.00 a month against WorldWinner's $3.50), a bank withdrawal option that Skillz says is processed faster, a stated refund when a player loses to a staff account, an automatic refund when no opponent is found within 7 days, and very large audiences around individual games, shown by App Store rating counts near 96,000 for Solitaire Cube.

Where WorldWinner has the edge on published terms: one account and one balance across more than 30 titles, web play alongside the apps, more listed deposit methods (including Venmo, American Express, and Discover), a stated 7 to 10 business day window for card and PayPal withdrawals against Skillz's standard 4 to 6 week guidance, licensed game brands, and an operating history that dates to 2000.

WorldWinner's weak points are real and covered elsewhere on this site. Card and PayPal withdrawals can take 7 to 10 business days and checks up to 8 weeks, withdrawing forfeits all Bonus Bucks, the inactivity fee is $3.50 per month, support is ticket and email only with no live chat, and complaint-site ratings are low (PissedConsumer 1.9 and Sitejabber 1.5, against Trustpilot 4.0 and App Store 4.6).

Neither service is a way to produce dependable returns. Both keep part of each entry fee, both match improving players against stronger opponents, and both say results depend on how a player scores against other people.

Skillz facts were taken on 2026-09-20 from Skillz's own support center, fairness page, and Android guide, from Firy Inc. investor releases, from Skillz Inc.'s Form 10-Q filed with the SEC for the quarter ended September 30, 2024, from App Store listings, and from developer sites. Litigation facts come from that SEC filing, from S.D.N.Y. opinions in case No. 1:24-cv-01646, and from dated reporting by Reuters, PocketGamer.biz, VitalLaw, and an Ashurst Perkins Coie case summary.
