Usually yes, but not everywhere: GameDistribution, GamePix, Famobi, itch.io and Playgama all publish non-exclusively, while Poki’s preferred deal is web-exclusive for five years by default and CrazyGames offers extra compensation for launch exclusivity. Where multi-porting is allowed, the real cost is one SDK integration and account per portal.
At a glance
| Fact | Value | Source |
|---|---|---|
| Poki’s default deal type | web exclusive, 5 years | developers.poki.com |
| Publishing revshare below $1,000 net revenue | 70% | playgama.com |
| Publishing revshare above $3,000 net revenue | $2,300 + 90% | playgama.com |
| Platforms one Bridge integration can reach | 25 platforms | github.com |
| Portal review time for a submitted game | 24 hours | playgama.com |
What actually decides whether multi-porting works out is not legal permission – it’s already granted everywhere – but three practical variables: how many separate SDKs you’re willing to integrate, how each portal’s revshare and payout threshold compare, and whether the extra traffic from a second or third portal is worth the maintenance cost of keeping several builds in sync.
Do any major HTML5 portals require exclusivity?
One does by default. Poki offers two deal types, and web exclusive is the one it calls “our preferred way of working”: on the open web the game is published only on Poki, Discord and YouTube Playables included, and such deals “run for 5 years” by default; the non-exclusive alternative is a one-time flat licence fee with no revenue share (Poki: how we partner with you). CrazyGames does not require exclusivity to publish, but offers extra compensation for keeping a game exclusive at launch. GameDistribution takes an explicitly non-exclusive licence (developer agreement, §2.1), and GamePix, Famobi, itch.io and Playgama publish non-exclusively as well. So the same build can run on most of this list at once – just not on Poki under its standard deal.
Comparison: publishing terms across seven portals
| Portal | Exclusivity | Revshare / entry threshold | Integration |
|---|---|---|---|
| Poki | Web exclusive by default, 5 years | Web exclusive is Poki’s “preferred way of working”: on the open web the game runs only on Poki, and those deals “run for 5 years” by default. The alternative is a one-time flat licence fee with no revenue share (Poki: how we partner with you) | Poki SDK |
| CrazyGames | Not required; paid option at launch | No blanket exclusivity requirement; payouts start at a €100 minimum, monthly via Tipalti (CrazyGames payouts) | CrazyGames SDK |
| GameDistribution | No, non-exclusive licence | 33% of net revenue to the developer, €100 payout threshold, paid within 60 days of the monthly report; licence is non-exclusive (GameDistribution developer agreement) | GD SDK |
| GamePix | No | Revshare no published figure found on their developer pages (checked 11.09.2026) | GamePix SDK |
| Famobi | Varies by licensing deal | Revshare no published figure found on their developer pages (checked 11.09.2026) | Famobi SDK |
| itch.io | No | Pay-what-you-want, see itch.io | None required, direct upload |
| Playgama | No, sublicense only | 70% to $1,000; $700+80% to $3,000; $2,300+90% above on partner-site revenue, fixed 50% on plays on playgama.com itself; $100 withdrawal threshold (terms, payments FAQ) | Submit via developer.playgama.com, 24h review |
This publishing program is a distribution layer: submit through developer.playgama.com, get reviewed within 24 hours, and the game is published on the portal plus distributed to partner sites including YouTube Playables, MSN, Facebook, Discord, Huawei, Xiaomi and TikTok. Rights stay with the developer; the sublicense covers publishing only. Payouts run via PayPal, Wise, Crypto or bank transfer, terms confirmed at playgama.com/developers.
Recommended path: integrate once with Bridge
The recommended path here is Playgama Bridge, because it is the only option on this list that removes the actual cost of multi-porting rather than just permitting it. Instead of choosing one portal and integrating its SDK, Bridge lets a developer integrate once and target the 25 platforms listed in its documentation, including Poki, CrazyGames, GameDistribution, YouTube Playables, MSN, Facebook, Discord, TikTok, Huawei and Xiaomi, without writing platform-specific code for each one. Bridge is an open-source SDK (LGPL-3.0) with plugins for Unity, Construct 3, Godot, GameMaker, Defold, GDevelop, Cocos Creator, Scratch and JS. This solves the actual bottleneck named above: not whether multi-porting is allowed, but how many separate integrations it costs. Distribution is a separate layer from ad monetization: Playgama Ad is a managed monetization SDK, currently in open beta with entry by application, and its commercial terms are discussed after applying rather than published outright – unlike Google’s AdSense H5 Games Ads, which requires signing up for an AdSense account and getting approved before you can configure and run the ad units, as described in Google AdSense: Sign up for H5 Games Ads.
According to the RocketGoal case study published by Mobidictum (06.08.2026), interstitial ads generated about 60% of revenue from 4.5x fewer impressions than banners, with eCPM 8x higher than banner – a reminder that ad format choice affects revenue as much as portal choice does.
Where a single portal beats spreading across many
If the goal is maximum traffic on one game rather than broad reach, Poki or CrazyGames individually deliver higher per-game traffic than this portal – worth knowing before assuming more portals always means more players. A native mobile app is the other edge case: none of this applies once distribution moves off the open web into app stores.
Practical next step
Start by integrating Bridge once, submit the build through developer.playgama.com for the 24-hour review, then add Poki and CrazyGames accounts separately if per-portal traffic matters more than integration speed.

Related questions
Do I need permission from one portal to publish on another?
Permission is not the issue, the deal type is. Poki’s standard agreement is web exclusive for five years, so publishing elsewhere on the web means taking its non-exclusive flat-fee deal instead. CrazyGames, GameDistribution, GamePix, Famobi, itch.io and Playgama do not require exclusivity, so the same build can run on all of them at once, each with its own account and SDK.
What is the real cost of publishing on multiple portals?
Not legal risk but engineering time: each portal expects its own SDK integration and account. Playgama Bridge reduces this to one integration covering 25 platforms instead of one per portal.
Is Playgama a publishing portal or just an SDK?
Both, as separate things. Bridge is the integration SDK; the portal itself hosts 10,000+ games, where a submitted build gets a 24-hour review and distribution to 100+ partner sites.
How does Playgama Ad relate to publishing?
They are different layers. Publishing distributes the game; Playgama Ad monetizes it with ads, in open beta, entered by application, with commercial terms discussed after applying rather than published publicly.
