The short version: Windows PCs already have a free offline card game built in (the Microsoft Solitaire Collection), and beyond that there are solid free options for hearts, spades, rummy, poker practice and deck builders that run with no internet connection once installed. Most sit under 200MB. The main job before installing anything is checking the publisher, the permissions it asks for, and where you downloaded it from, since card games are a common wrapper for unwanted extra software.

What "offline" means for a card game
An offline card game is one that, once installed, does not need a live internet connection to deal a hand, run the rules or keep your score. Some games marketed as offline still want a one time internet connection to activate or to check for updates, and some free games only switch on the offline mode after you have played through an online tutorial once. When a listing says "offline" but also lists ads, always assume the ads need a connection even if the gameplay does not, so expect an occasional ad break when connected and a quieter, ad-free experience once you switch on flight mode.
Solitaire variants worth having
Solitaire is the safest starting point because it is pre-installed on most Windows 10 and 11 machines as the Microsoft Solitaire Collection, which bundles Klondike, Spider, FreeCell, Pyramid and TriPeaks in one app, all playable offline once downloaded from the Microsoft Store. It needs under 250MB of storage and runs on almost any laptop from the last decade. If you want more variants than that collection covers, look for a standalone FreeCell or Spider pack that states "offline" and "no internet required" in its own description, and check the storage size listed, since a bloated solitaire app (much over 300MB) is usually carrying extra bundled software you do not need.
Hearts and spades for offline play against the computer
Hearts and spades are trick taking games that most people learned against three computer opponents rather than online, and that is still the easiest way to play them offline. Look for a standalone hearts or spades app rather than a "card games bundle," since bundles are more likely to include games you never open plus more background permissions. A well built hearts or spades app for PC typically sits between 50MB and 150MB, plays entirely against computer opponents once downloaded, and should not ask for contacts, microphone or camera access at any point, since none of those are needed to deal cards.
Rummy and gin rummy against the computer
Rummy variants (classic rummy, gin rummy, 500 rummy) are widely available as single player apps against computer opponents, and the offline versions tend to be small, often under 100MB, because the game logic is simple compared to a 3D game. The thing to check with rummy apps specifically is whether "multiplayer" is the default mode, since some rummy apps are built primarily for real money play with friends and only include a computer opponent mode as an afterthought. If real money or "cash rummy" appears anywhere in the app's own description, treat it as a different category of app to a plain offline single player game, since it will need account verification and a live connection to work at all.
Poker practice apps (not real money poker)
There is a clear line between a poker practice or "video poker" style app, which plays against the computer with no real money involved, and an online poker room, which needs a constant internet connection and involves real stakes. For offline poker practice, look specifically for wording like "single player," "vs computer" or "practice mode" in the app description, and avoid anything asking you to link a payment method before you have even played a hand, since a genuine offline practice app never needs your card details. These apps are usually small, well under 150MB, since they are mostly card graphics and simple odds logic.
Deck builders and solitaire-style strategy games
Deck builders (games where you build and improve a deck of cards as you play, rather than just being dealt a hand) are a step up in size and complexity from straight solitaire. A lightweight, casual deck builder for PC usually falls between 100MB and 500MB, while a fuller deck building game with more artwork, animation and content can run from 1GB up to several GB. Many popular deck builders started as offline-friendly single player games and later added optional online modes, so check specifically whether the "single player" or "campaign" mode is confirmed to work fully offline, rather than assuming it because the game has a single player option.
Storage size bands to expect
- Under 100MB: Classic solitaire, hearts, spades, simple rummy, basic poker practice apps.
- 100MB to 500MB: Solitaire collections with several variants bundled, casual deck builders, card games with more detailed art or animation.
- 500MB to 2GB: Fuller deck building games with campaigns, voice acting or 3D table graphics.
- Over 2GB: Large strategy or role playing games that use a card mechanic as one part of a much bigger game world; these are not casual card games in the sense most people are looking for.
If a plain solitaire or hearts app is listed at several gigabytes, that is a sign it is bundling something else, or the listing is misleading about what the app really is.
How to check a download is safe before you install it
A handful of checks take under two minutes and rule out almost every problem:
- Check the publisher name. A listing from an unnamed or newly registered publisher, with no other apps and no history, is a higher risk than one from a publisher with several other apps and reviews going back years.
- Read the permissions before you accept them. A card game has no reason to ask for your contacts, your location, your microphone or the ability to read files outside its own folder. If it asks for any of those, that is a reason to stop and reconsider, not to click through.
- Check the file size against the description. A simple solitaire app that is several gigabytes, or a "free" app that needs a large download before you have even started a level, is worth a second look.
- Look at recent reviews, not just the star rating. Scan the last month of reviews specifically for mentions of pop up ads that will not close, unexpected charges, or the app installing something else alongside it.
- Use your Windows built in antivirus. Windows Security (built into Windows 10 and 11) will flag a large share of obviously unsafe installers automatically; never turn it off to force an install through.
- Prefer the Microsoft Store over a random website installer where possible. Apps distributed through the Microsoft Store go through a basic review process that a direct .exe download from an unfamiliar website does not.
Mistakes people make downloading offline card games
- Assuming "free" means no ads. Free offline card games are almost always ad supported when you have a connection, and some show ads even offline using previously cached adverts. If you want zero ads, check for a specific "ad free" or paid version rather than assuming.
- Downloading a "bundle" instead of one game. Bundles that promise "500 card games in one app" tend to be lower quality overall and carry more background processes than a single, well reviewed standalone game.
- Ignoring the update prompt forever. An app that has not been updated in several years is more likely to have unpatched issues, even if it still opens and plays fine.
- Clicking through permission requests without reading them. This is the single biggest way unwanted extra software ends up bundled with a simple card game.
- Installing from a search ad rather than the actual store or publisher page. A sponsored search result is not proof of a genuine or safe listing; scroll past ads to the actual store listing.

Frequently asked questions
Do I need an internet connection at all to play these once installed?
For a genuine single player, offline mode, no, the core gameplay works without a connection. Some apps still want an internet connection briefly for ads to load, or to sync your progress and achievements, but the actual card game itself keeps working, and many will simply pause the ad slot when you are offline.
Is the Microsoft Solitaire Collection really free?
Yes, it is free to download and play, supported by ads when you have a connection, with a paid ad free option available inside the app if you want to remove them. It comes pre-installed on many Windows machines or is available directly from the Microsoft Store.
Why do some card games ask for so much storage for something so simple?
Card game logic itself is small, but high resolution card art, animated dealing and shuffling effects, background music and multiple game modes all add to the size. A game that looks closer to a polished video game than a basic app will naturally sit at the higher end of the storage bands above.
Are offline poker practice apps the same as online poker?
No. Offline poker practice apps play against computer opponents with no real money and no live players, which is a completely different category to an online poker room. If an app asks you to deposit funds or link a bank account, it has moved out of the offline practice category entirely.
How do I know if a "deck builder" game will really work offline?
Check the app's own listing for the words "offline," "no internet required" or "single player campaign," and check recent reviews for anyone confirming they play it on a flight or with their internet off. If the listing only mentions online or multiplayer modes, assume it needs a connection until you can confirm otherwise.
