Licensing Games to Portals

The Web Game Portal Landscape

Web game portals are websites that aggregate browser games into a curated library, attract players through their own branding and SEO, and monetize through advertising served alongside the games. They function as marketplaces where players discover and play games for free, while developers benefit from the portal's audience reach and ad infrastructure.

The portal ecosystem is dominated by a handful of major platforms. Poki is the largest, serving over 60 million monthly active users across a global audience. Poki curates its catalog carefully, accepting only games that meet quality thresholds for gameplay, art, and technical performance. CrazyGames reaches approximately 35 million monthly users and is known for accepting a wider range of game genres, including more complex mid-core titles. GameDistribution operates as both a distribution platform and an ad network, syndicting games across a network of publisher websites. Armor Games and Newgrounds cater to more dedicated gaming audiences with longer histories in the browser game space. CoolMath Games occupies a niche focused on educational and puzzle games, attracting a younger audience and school traffic.

Each portal has different audience demographics, content policies, technical requirements, and revenue terms. A game that performs well on Poki may not match the audience expectations on Newgrounds, and vice versa. Understanding each portal's characteristics helps you target the right platforms for your game's genre and style.

Revenue Share vs. Flat-Fee Licensing

Revenue sharing is the standard model for most portal deals. The portal serves ads around and within your game, collects the ad revenue, and splits it with you on a monthly or quarterly basis. The developer's share typically ranges from 50% to 80%, depending on the portal, the game's exclusivity status, and its traffic performance.

Revenue share advantages include no upfront negotiation about the game's value, automatic scaling (better-performing games earn more), and ongoing income as long as the game remains on the portal. The disadvantage is uncertainty: you do not know how much you will earn until the game is live and generating traffic. Revenue depends on the portal's ad rates, the game's engagement metrics, and the geographic distribution of players (since CPMs vary significantly by country).

Typical revenue share earnings for a well-performing casual game on a major portal range from $200 to $2,000 per month, though breakout hits can earn significantly more. Games that achieve strong retention and session length metrics tend to earn disproportionately more because engaged players generate more ad impressions per session.

Flat-fee licensing pays the developer a one-time fixed amount for the right to host the game. This model is less common but still used, particularly for smaller casual games or for portals that prefer to own their content outright. Flat fees range from a few hundred dollars for simple games to $5,000 or more for polished, high-quality titles with strong engagement potential.

The flat-fee model gives you guaranteed income regardless of how the game performs on the portal, which reduces risk but also eliminates upside. If your game becomes a hit on the portal and generates significant traffic, you receive the same flat fee as if it had performed poorly. For this reason, most established developers prefer revenue sharing for their strongest titles and may accept flat fees for smaller or older games in their catalog.

Exclusive vs. Non-Exclusive Deals

An exclusive license grants one portal the sole right to distribute your game, either permanently or for a defined time period. In exchange for exclusivity, portals offer higher revenue shares, larger flat fees, or promotional placement that increases visibility. Poki and CrazyGames both offer preferential terms for exclusive titles, sometimes including featured placement on their homepage or in curated collections.

The risk of exclusivity is concentration. If you license exclusively to one portal, your entire portal revenue depends on that single platform's traffic, ad rates, and continued operation. If the portal changes its terms, reduces your game's visibility, or shuts down, you lose your distribution channel. Timed exclusivity (such as a 90-day exclusive window before opening to other portals) mitigates this risk while still securing the benefits of the exclusive deal during the launch period.

A non-exclusive license allows you to distribute the same game across multiple portals simultaneously. This maximizes your total reach but typically comes with lower revenue shares or no promotional advantages from any individual portal. Non-exclusive distribution is the safer strategy for most developers because it diversifies income across multiple platforms and provides fallback options if any single portal underperforms.

Universal distribution platforms like Playgama Bridge simplify non-exclusive multi-portal distribution. These services wrap your game in a compatibility layer that handles the different SDK requirements of each portal, allowing you to publish a single build to Poki, CrazyGames, Facebook Instant Games, and other platforms simultaneously. Playgama reports developer revenue retention of up to 80%, which is competitive with direct portal deals while eliminating the per-portal integration work.

Technical Requirements for Portal Distribution

Each portal has specific technical requirements that your game must meet before it will be accepted. While the details vary by portal, several requirements are common across the major platforms.

SDK integration is typically mandatory. Portals provide a JavaScript SDK that handles ad serving, analytics, and sometimes user authentication. Your game needs to call SDK methods at appropriate moments: trigger an interstitial ad between levels, offer a rewarded video at natural reward points, and report gameplay events for the portal's analytics. The SDK also manages loading indicators and ensures that ads are served in compliance with the portal's advertiser agreements.

Responsive design is expected by all major portals. Your game should adapt to different screen sizes and aspect ratios, working on both desktop monitors and mobile phone screens. Most portal traffic comes from a mix of desktop and mobile, so a game that only works at one resolution will lose a significant portion of its potential audience.

Performance requirements vary but generally mandate fast loading times (under 10 seconds for initial load), smooth frame rates (30+ FPS on mid-range devices), and reasonable memory usage. Portals test submitted games on standard hardware and reject titles that stutter, crash, or take too long to become playable. Compression of assets, lazy loading of non-critical resources, and efficient rendering are important for meeting these benchmarks.

Content policies restrict certain types of content, though the specific rules differ by portal. Most portals prohibit explicit violence, sexual content, gambling mechanics, and content that targets children in manipulative ways. CoolMath Games has stricter content requirements due to its educational focus and younger audience. Newgrounds has more permissive content policies reflecting its community-driven, creator-friendly philosophy.

No external links or competing ads is a universal requirement. Your game should not link to other websites, show your own ads that compete with the portal's ad serving, or attempt to redirect players away from the portal. Some portals also prohibit in-game purchases that bypass the portal's revenue split, though this varies by platform.

How to Submit Your Game

The submission process is similar across most portals. You create a developer account on the portal's developer platform, upload your game build (usually as a ZIP file containing the HTML5 game files), fill out metadata (title, description, category, tags, screenshots, thumbnail), and submit for review. The portal's team evaluates the game for quality, technical compliance, and content policy adherence, then either approves it for publication or returns it with feedback for improvements.

Review times vary from a few days on smaller portals to several weeks on larger ones like Poki, which receives many submissions and curates carefully. Improving your approval chances starts with polish: a clean UI, responsive controls, clear visual feedback, engaging first-session experience, and compliance with all stated technical requirements.

Some portals accept direct submissions from developers while others work through an invitation or application process. CrazyGames and GameDistribution accept open submissions through their developer portals. Poki is more selective and may require an application or referral for initial access, though they periodically run open submission windows.

Maximizing Portal Revenue

Revenue on portals is driven by three factors: the number of players who try your game, the percentage who return for additional sessions, and the average session length. Optimizing all three maximizes your ad revenue share.

First-session hook: your game's first 30 seconds determine whether a player stays or bounces. Portal players browse casually and have short attention spans. The game should be playable within seconds of loading, with a tutorial or first level that is immediately engaging and clearly communicates the core gameplay. Avoid long loading screens, unskippable cutscenes, or complex menus before the player can start playing.

Session depth: once a player is hooked, the game should provide enough content and progression to sustain sessions of 5 to 15 minutes or longer. Progressive difficulty, unlockable content, score challenges, and daily rewards all contribute to longer sessions. Each additional minute of play translates directly to additional ad impressions and higher revenue.

Return motivation: features that bring players back for additional sessions multiply your revenue per player. Progression systems (levels, experience, unlocks), social features (leaderboards, challenges), daily bonuses, and regular content updates all improve return rates. A player who visits 10 times generates roughly 10x the revenue of a one-time player, making retention the single highest-leverage metric for portal income.

Studying the top-performing games on each portal provides practical insights. Look at what genres dominate, how those games structure their first session, what retention hooks they use, and how they integrate ad placements. Adapting proven patterns to your own game's design can significantly improve its portal performance.
