Why We'll Never Show You an Ad
Go to almost any card game site on the internet and you will encounter: a banner ad at the top, a skyscraper ad down the right side, a fullscreen interstitial that appears before you can play, a countdown timer on that interstitial, a "skip ad" button that appears at the five-second mark, a pop-up encouraging you to install their mobile app, and — on some sites — an ad that plays a video with sound before you have clicked anything.
You deal your first hand and there is a banner ad between the tableau and the foundations. You click the stock pile and a second interstitial appears. The "X" to close it is a small gray button in a corner that requires two attempts to click on mobile.
This is not an accident. It is what a business optimized for advertising revenue looks like from the user's perspective.
Cards4.net does none of this. We will not add ads in the future, either. This post explains why — not as marketing, but as our product philosophy.
What This Means for Players
No ads means no video interstitial before a new deal, no banner pushing the board down, and no dark pattern designed to make you misclick. No third-party ad tracking means no retargeting pixel following you after you close the site. No login wall means you can start Klondike Solitaire, FreeCell, or Spider Solitaire without creating an account first.
This is partly a privacy stance and partly a product stance. Card games are better when the interface is quiet.
Why Ad-Supported Games Go Wrong
Advertising revenue is calculated as: (impressions) × (click-through rate) × (value per click). To maximize this, you need users to see a lot of ads (maximizing impressions) and spend a lot of time on the site (maximizing the opportunity for impressions). This creates a direct financial incentive to make the experience stickier, not better.
The dark patterns on ad-supported game sites are not the product of careless design. They are the product of careful design — toward the wrong goal. Countdown timers before games load keep users waiting, which increases the chance they will see an ad. Interstitials appear at natural pause points — between games, after wins — because that is when users' attention is available to be captured. Fake "X" buttons reduce successful ad dismissals, increasing ad completion rates.
The worst of these patterns blend into the product itself. A game that is slightly too frustrating to win keeps you playing longer. Streak-shaming notifications ("you haven't played in 3 days — your streak is at risk!") generate anxiety that drives return visits. None of these are good for you. All of them are good for the site's ad revenue.
The Privacy Problem with Ads
Ad networks require audience data to function. To show you a targeted ad — which is more valuable than a random ad — the network needs to know something about you: your age, interests, browsing history, location, income bracket. This data comes from tracking pixels, cookies, and cross-site scripts embedded on every page of the site.
A typical ad-supported website loads scripts from Google, Meta, Amazon, and a dozen other advertising networks simultaneously. These scripts run in your browser, record your behavior, and share it with their respective networks. The site owner often has limited visibility into exactly what is being tracked — they have agreed to the terms of service, but the terms are long and the actual data collection is opaque.
Cards4.net has none of this. Our only analytics tool is Plausible Analytics — a privacy-first, European-hosted service that counts visits without tracking individuals and does not share data with third parties. In developer tools you'll find no tracking pixels or ad network scripts.
We also ask for consent before loading even Plausible. If you decline, nothing loads at all.
What This Costs
The honest answer: it limits how we can fund the site.
Ad revenue on a card game site is not trivial. Popular solitaire sites with millions of monthly visitors can generate meaningful revenue from advertising — enough to cover hosting, development, and then some. We chose not to take that money, which means we need a different model or we run lean.
We currently run lean. Cards4.net is a small site. The infrastructure costs are modest because the product is well-engineered. There are no venture capitalists involved, no growth targets to hit, no board demanding we "monetize the user base."
This also means we cannot grow through paid advertising ourselves. We grow through organic search, word of mouth, and usefulness. It's slower, but it avoids the incentive spiral that breaks ad-supported products.
What We Are Exploring Instead
We are open to sustainable funding that does not compromise the product. Some possibilities:
Optional donations or tips. A "support the site" button that does nothing to the product if you ignore it. No guilt, no pressure, no locked features.
Privacy-respecting paid features. If we ever add a paid tier, it will offer genuinely new things — not remove limitations we artificially imposed. A paid tier that unlocks an "ad-free experience" when there were never ads is not a paid tier; it is retroactive extortion.
Affiliate links for physical card games or books. A small, clearly disclosed commission on genuinely relevant external purchases. No tracking pixels, just standard affiliate URL parameters.
What we will not do: accept advertising of any kind, install third-party tracking of any kind, create artificial limits to remove, or introduce dark patterns — however subtly.
Structural vs Aspirational Promises
The important thing about our commitment to being ad-free is that it is structural, not aspirational.
An aspirational promise sounds like: "We believe in privacy and will never show you ads." This is easy to make and easy to break. If revenue pressure mounts and the founder leaves or sells the company, a new owner can decide that ads are now acceptable and point out that the old promise was just a feeling.
A structural promise is built into the business model itself. We have no ad network accounts, no advertising infrastructure, no relationships with demand-side platforms, and no revenue that depends on user attention. Adding advertising would require actively building this infrastructure from scratch. This is not impossible — nothing is — but it is a higher bar than just toggling a setting.
We also have no investors with the ability to demand we add ads. There is no cap table with a board seat that could vote for monetization. The site is funded by its operator. This limits our scale, and we accept that trade-off.
What It Looks Like in Practice
No ads means the game is the whole screen. When you open Klondike Solitaire on Cards4.net, you see the card game, a few controls, and no banner, sidebar, or countdown timer.
No dark patterns means the "new game" button starts immediately. There is no "are you sure?" dialog, no "you're on a winning streak" modal, and no pre-checked newsletter box. The hint button shows a hint. The undo button undoes. Settings work without sign-in.
The Relationship Between Ads and Design
One thing that is easy to miss: removing ads changes how you think about the product.
When revenue depends on time-on-site, you are subtly incentivized to make the game slightly worse — slightly more frustrating, slightly less clear, slightly harder to leave. These incentives do not require conscious decisions; they operate through A/B test results that favor higher engagement numbers over user happiness.
When there are no ads, the incentive is simply to make the game good. A game you enjoy and recommend to a friend is better for us than a game you spend twenty minutes on because you cannot figure out how to close a pop-up.
This sounds obvious, but it is genuinely rare in practice. Most product decisions are made under some kind of monetization pressure. Ours are not.
Just Play the Card Games
We are not trying to build an audience. We are not trying to become a platform. Cards4.net is a card game site — Solitaire, FreeCell, Spider, Hearts, Spades, Euchre — and the goal is to make those games as good as possible to play.
That is it. There are no ads because the site was built by someone who wanted to play solitaire without ads, and this is what that looks like.
The Business Model Math
It's worth being concrete about the numbers, because "we run lean" is easy to say and hard to evaluate without context.
A card game site with meaningful traffic can generate real advertising revenue. Industry estimates for casual gaming sites put CPM (cost per thousand impressions) somewhere between $2 and $8 for display ads, higher for video. A site with 100,000 monthly active users, each generating 10 page views per session and playing three sessions per month, is looking at roughly 3 million impressions per month. At a $4 CPM, that's $12,000 per month in gross ad revenue. Not a fortune, but not nothing.
We chose not to take that money. So what does our model actually look like?
Infrastructure costs for a well-engineered small site are lower than most people assume. We run on Hetzner, not AWS. A single app container plus a Postgres sidecar, behind an nginx reverse proxy on a shared server. The monthly infrastructure bill is under $100. Plausible Analytics and Sentry add a small amount on top. Total operating cost is well under $200 per month.
That means the site doesn't need much revenue to be sustainable. A few hundred users who donate $5 once a year would cover costs. We're not there yet — we haven't launched a donation option — but the math is encouraging. The gap between "costs nothing to run" and "needs significant revenue" is much smaller than it would be for a site with AWS bills, a CDN contract, and a team of engineers to pay.
The longer-term model we're exploring is optional paid features — things that add genuine value rather than removing artificial restrictions. A paid tier that unlocks an "ad-free experience" when there were never ads is not a paid tier; it's retroactive extortion. If we ever charge for something, it will be for something new.
What "No Tracking" Actually Means in 2026
"No tracking" is a phrase that gets used loosely, so here's what it means specifically on Cards4.net.
What we don't do:
- Google Analytics or any Google tracking script
- Facebook Pixel or any Meta tracking
- Retargeting pixels of any kind (no "follow you around the web" ads)
- Browser fingerprinting (no canvas fingerprinting, no font enumeration, no WebGL fingerprinting)
- Cross-site tracking cookies
- Session recording tools (no Hotjar, no FullStory, no Microsoft Clarity)
- Email tracking pixels in any outgoing email
What we do:
- Plausible Analytics, loaded only after you give consent. Plausible counts page views without tracking individuals, uses no cookies, stores no personal data, and is hosted in the EU under GDPR. If you decline consent, Plausible does not load at all — not even a single request is made.
- Sentry for error reporting, with a PII scrubber that strips email addresses, IP addresses, and any user-identifiable data before events are sent. Sentry sees stack traces and error messages, not user data.
You can verify all of this yourself. Open your browser's developer tools, go to the Network tab, and load Cards4.net. You'll see requests to our own domain, to Plausible (if you consented), and to Sentry (for error reporting). Nothing else. No third-party scripts phoning home to advertising networks.
A Note on Affiliates
We mentioned in an earlier section that affiliate links for physical card games or books are something we're open to exploring. We want to be precise about what that would and wouldn't look like.
What it would look like: a clearly labeled "buy this book" link at the bottom of a relevant guide, with a standard affiliate URL parameter that tells the retailer we sent you. If you buy the book, we get a small commission. The link is disclosed. There are no tracking pixels involved — just a URL parameter.
What it would not look like: sponsored content where we write favorably about a product because we're paid to. Undisclosed affiliate relationships. Links inserted into articles where they don't belong because the commission is good. Partnerships with companies whose products we wouldn't recommend anyway.
We don't currently have any affiliate relationships. If we add them, they'll be disclosed clearly on the relevant pages and in a site-wide disclosure. The bar for inclusion is: would we link to this even without the commission? If the answer is no, the link doesn't go in.
No sponsored posts. No "partner content." No upsells to premium versions of things we've reviewed. The content on Cards4.net is written to be useful, not to generate revenue from the links inside it.
FAQ
Q: Does Cards4.net show ads?
No. Cards4.net is designed as an ad-free card game site. There are no banner ads, video interstitials, sponsored placements, or ad-supported game screens.
Q: Does Cards4.net use third-party ad tracking?
No. We do not use ad pixels, retargeting scripts, browser fingerprinting, or session replay tools. Plausible Analytics only loads after consent, and Sentry error reports are scrubbed before they leave the app.
Q: How does Cards4.net stay sustainable without ads?
By staying small, keeping infrastructure modest, and avoiding business models that require attention extraction. Optional donations or genuinely useful paid features are possible; making the free games worse to sell relief from that experience is not.
Q: Can I play without signing in?
Yes. Guest play is supported. Sign-in exists for account-linked features, not as a barrier before playing a card game.
