WorldWinner vs Solitaire Clash: How They Compare

Both games are timed Klondike solitaire scored against another player. Each side gets the same deal, the clock runs, and the higher score takes the prize. The card game is the same; the platforms around it differ.

Solitaire Clash is a dedicated app. The App Store lists it as Solitaire Clash: Win Real Cash from seller Aviagames Inc. AviaGames describes free Gem tournaments, cash tournaments, weekly events, and no ads during a match. It suits a phone-first player who wants one solitaire game and values a very large base of App Store ratings.

WorldWinner's Solitaire Rush sits inside a catalog of more than 30 titles, including three other solitaire games (Spider Solitaire, Freecell Solitaire, and Pyramid Solitaire Lucky 13s), and it can be played in a desktop browser. It suits a player who wants solitaire variety, published point values, web play, or WorldWinner's statement that players never face bots.

On either platform, entry fees are real spending and winnings are never guaranteed.

Every cell below is taken from the named company's own published material or a store listing, checked on 2026-09-20. WorldWinner cells match this guide's fact sheet and its Solitaire Rush page.

Solitaire Clash, as AviaGames describes it: a standard 52-card deck is arranged into seven tableau columns, cards are moved by suit in ascending order from the Aces onto foundation piles, and the player taps to bring cards from the stockpile. AviaGames says speed and accuracy raise the score, with higher rewards for quick clears, and that players of all levels get the same card layouts and time limits. Its product page does not publish a point table, so this guide states no point values for Solitaire Clash.

Solitaire Rush, as WorldWinner's help center describes it: the same 52-card, seven-column Klondike deal, played against a countdown clock. WorldWinner publishes the scoring: 10 points for each card revealed, 10 for each card played from the deck, and 50 points for an Ace on its pile, falling by 5 per card to a floor of 5, plus a time bonus. Draw pile resets carry a cost: in 3-Card mode the first two are free and each later reset costs 20 points, and in 1-Card mode every reset costs 100 points.

Solitaire Rush has five published modes: 3-Card Draw, 1-Card Draw, Any Card, Queens Only, and Ace in the Hole. WorldWinner's corporate site says Solitaire Rush players receive the same card layout and compete for the highest score. Because the values are public, a player can work out in advance that low cards on the ace piles and avoided resets matter most, which is what this guide's Solitaire Rush strategy page covers.

AviaGames' support FAQ uses Solitaire Clash as its own example of identical conditions: it says both sides face the same initial hand with all cards, including covered cards, in the same order, with the same time and the same scoring rules. On the narrow question of whether opponents get the same deal, both companies publish a clear yes.

Beyond Klondike, WorldWinner offers Spider Solitaire, Freecell Solitaire, and Pyramid Solitaire Lucky 13s. AviaGames' site points Solitaire Clash players to other solitaire apps it publishes, such as Solitaire Slam, Solitaire Venture, and Solitaire Infinite, which are separate downloads.

Both companies describe skill matching, and both publish a statement about who the opponent is. The statements are not the same, so they are set out here as each company words them.

WorldWinner: opponents are matched by a per-game skill rating, and WorldWinner states that players never face bots. Its help center says most tournaments are asynchronous, meaning the opponent is a real player who plays the same round at a different time. Multi-accounting and collusion are banned. These are WorldWinner's statements, and this guide has not audited its matching system.

AviaGames: its support FAQ, checked on 2026-09-20, says its algorithms strive to match players with real, live players of similar skill. The same FAQ says that when no suitable opponent is logged in, a player may be matched with a recorded game from a real player of similar skill, which AviaGames calls a Historical Playthrough. AviaGames states that in those matches it generates the profile information shown, and that if a Historical Playthrough score wins, AviaGames retains the prize. It also states that every player in a match gets identical setup, time, and rules. This disclosure applies to AviaGames titles generally, including Solitaire Clash.

Readers can compare the two published policies directly. Neither statement is a guarantee of results: in a score contest the higher score takes the prize, most entrants do not take the top prize, and winnings are never guaranteed on either platform.

Two federal court matters involving AviaGames, the publisher of Solitaire Clash, are on the public record. This guide reports them from the court documents, the SEC filing, and the dated reporting listed under Sources, and it draws no conclusion about the allegations.

Matter 1, a patent case between companies: Skillz Platform Inc. v. AviaGames Inc., No. 5:21-cv-02436, U.S. District Court for the Northern District of California. Skillz sued in April 2021, alleging that the Pocket7Games app copied its patented tournament platform. AviaGames denied the allegations, and its attorney told the jury that its technology works differently, as reported by Reuters on February 9, 2024. On February 9, 2024, a federal jury in San Jose found that AviaGames willfully infringed U.S. Patent No. 9,649,564 and awarded Skillz $42.9 million, according to Reuters and to the quarterly report Skillz filed with the SEC for the period ended September 30, 2024. The verdict concerned patent infringement. It did not decide any allegation about bots.

Current status of matter 1: settled. The same SEC filing states that on April 13, 2024, Skillz, Big Run Studios, and AviaGames settled both the patent case and a separate false advertising and copyright case, that AviaGames agreed to pay a total of $80.0 million in exchange for dismissal of both actions, and that the total includes $7.5 million per year for four years from March 2025 as royalties for a license to the patent family.

The bot allegations arose inside that case. Reuters reported on November 28, 2023 that Skillz told the court in August 2023 that discovery showed AviaGames used bots in its cash games. Reuters reported that AviaGames denied using bots to manipulate its games and countered in a court filing that Skillz "engages in the exact conduct it falsely accuses AviaGames of carrying out."

Matter 2, a consumer class action: Pandolfi et al. v. AviaGames, Inc. et al., No. 3:23-cv-05971-EMC, U.S. District Court for the Northern District of California, filed in November 2023. According to the district court's description of the complaint, two players allege that AviaGames represented that players compete against other people of similar skill when they were in fact matched against bots. They seek to represent a class of people who lost money playing AviaGames titles, and they bring claims under California consumer protection statutes and the federal Racketeer Influenced and Corrupt Organizations Act (RICO). These are allegations. No court has ruled on whether they are true, and AviaGames has denied using bots to manipulate its games.

Current status of matter 2: pending in the district court. AviaGames asked the court to send the dispute to private arbitration under its terms of service. The district court denied that motion in September 2024, finding parts of the arbitration agreement unconscionable. The U.S. Court of Appeals for the Ninth Circuit affirmed on August 27, 2025 (No. 24-5817, an unpublished memorandum). AviaGames petitioned the U.S. Supreme Court, which denied certiorari on May 18, 2026 (No. 25-1008). Those rulings are about arbitration only. They mean the case proceeds in court, and they are not findings on the bot allegations. As of 2026-09-20, this guide found no record of a judgment, a class certification ruling, or a settlement in the class action.

Reuters' November 28, 2023 report describes the class action as covering games like blackjack, solitaire, and virtual pool, so solitaire titles are within what the plaintiffs describe. That is a description of the complaint and not a finding about Solitaire Clash.

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 up to 8 weeks. WorldWinner's terms allow a $1.75 processing fee on check requests under $10. A deposit is required before withdrawing, and withdrawing forfeits all Bonus Bucks. WorldWinner's terms also set an inactivity fee of $3.50 per month once a cash account has gone 6 consecutive months without a login.

AviaGames (Solitaire Clash): its support FAQ lists Venmo, PayPal, Apple Pay, Visa, Mastercard, Amex, and Discover as payment methods, and its product pages describe withdrawals through PayPal. Its Terms of Service, last updated August 18, 2025, set a minimum withdrawal of US$5.00, say withdrawal requests may take up to 15 days to process, and say AviaGames may charge a withdrawal processing fee based on the player's transaction activity. The support FAQ says it may take 7 or more days for a bank or PayPal account to receive the money. The terms state that starting a withdrawal forfeits all Bonus Cash in the account, and that Bonus Cash cannot be cashed out.

The two bonus systems work alike in the ways that catch players out: promotional credit on both platforms covers only a small share of each entry fee, cannot be withdrawn, and is forfeited when a withdrawal is requested. Anyone comparing welcome offers should read that rule on both sides first.

WorldWinner's terms list six states where cash competitions are not offered: Arkansas, Connecticut, Delaware, Louisiana, South Carolina, and South Dakota. WorldWinner's state availability article adds game-type limits: Indiana and Maine: no card games for cash. Arizona and Florida: no Progressive, Mega Event, or Fixed Prize Unlimited Entry tournaments. Players must be 18 or older (higher in some jurisdictions). Solitaire Rush is a card game, so on WorldWinner's published list it is not offered for cash in Indiana or Maine.

AviaGames' Terms of Service, last updated August 18, 2025, say it does not offer cash competitions to players accessing its services from Arkansas, Delaware, Louisiana, South Carolina, or South Dakota, or from U.S. territories including Puerto Rico, and that it does not offer card game cash competitions in Indiana or Maine. Players must be at least 18. Solitaire Clash is a card game, so the Indiana and Maine limit applies to it as well.

AviaGames' two published lists do not match exactly. The Solitaire Clash App Store listing, checked on 2026-09-20, says cash matches are unavailable in Arkansas, Delaware, Louisiana, Michigan, South Dakota, Maine, and Indiana, and in U.S. territories including Puerto Rico, and that players there can still play free matches. The terms name South Carolina and do not name Michigan. A player in either state should rely on what the app shows at sign-up.

On devices, the two differ. WorldWinner offers web play at web.worldwinner.com, an iOS app on the App Store, and an Android app that is a direct download from the WorldWinner corporate site and is not on Google Play. AviaGames lists Solitaire Clash on the App Store and the Samsung Galaxy Store and as an Android APK. For Samsung owners, a store listing is a simpler install than a direct download, which is a point in Solitaire Clash's favor.

This section reports each company's published list. It is not legal advice and not a conclusion about what is lawful in any state.

Where Solitaire Clash has the edge: a higher App Store rating on a much larger base (4.8 from about 461,000 ratings as of 2026-09-20, against 4.6 for WorldWinner's app), a Samsung Galaxy Store listing, a stated no-ads match experience, and a detailed published statement that both sides get the same deal down to the covered cards. A single popular game can also mean a larger pool of opponents for that one game, although neither company publishes player counts per title.

Where WorldWinner has the edge: published point values and reset costs, five Solitaire Rush modes, three other solitaire titles on the same balance, web play, a lower minimum withdrawal ($1.75 against US$5.00), a history going back to 2000, and an unqualified published statement that players never face bots.

WorldWinner's weak points should be weighed too. Card and PayPal withdrawals can take 7 to 10 business days, and checks up to 8 weeks. Withdrawing forfeits all Bonus Bucks. An inactivity fee of $3.50 per month applies once a cash account has gone 6 consecutive months without a login. Support is by ticket and email with no live chat, the Android app is not on Google Play, and complaint-driven sites rate it poorly (PissedConsumer 1.9, Sitejabber 1.5).

The pending class action against AviaGames is unresolved, and AviaGames denies its allegations. This guide does not treat an allegation as a finding, and it does not claim that any individual Solitaire Clash match involved a bot.

This comparison was compiled on 2026-09-20. Statements about Solitaire Clash and AviaGames come from AviaGames' own website, support FAQ, and Terms of Service, from the Apple App Store listing, from court documents and dockets, from a Skillz filing with the U.S. Securities and Exchange Commission, and from dated reporting by Reuters and the National Law Journal. Every source is listed under Sources. Statements about WorldWinner come from WorldWinner's published terms, help center, corporate site, and App Store listing.

This guide is independent. It is not operated by WorldWinner, by AviaGames, or by any party to the lawsuits described. It focuses on WorldWinner, which readers should weigh when reading a comparison published here. No one at this guide tested either product for this page, and the page offers no opinion on the quality of either company's games.

Court matters move. A pending case can be dismissed, settled, or decided after a page is reviewed, and allegations in a complaint are not findings. Terms, fees, state lists, and app ratings also change.
