To monetize HTML5 games, integrate a portal SDK (Poki, CrazyGames) for revenue share, plug in ad networks (AdinPlay, GameMonetize, CPMStar, Playgama) for self-hosted inventory, layer in in-app purchases through Stripe or Xsolla, and pursue licensing or sponsorships for flat-fee…

The right mix combines two or three models — most commonly rewarded video plus interstitials plus a small IAP store.

Earnings vary widely: a single title may earn three to four figures, while a sustained portfolio is what most developers cite when they describe HTML5 games as a full-time income.

HTML5 games are monetized through five main routes: portal revenue share (Poki, CrazyGames), direct ad-network integration (AdinPlay, GameMonetize, CPMStar, Playgama), in-app purchases, sponsorships and licensing deals, and subscriptions. Most indie titles combine two or three.

The right mix depends on game length, retention, and whether you self-host or publish through a portal. Different models suit different game types.

Short-session arcade titles — runners, hyper-casual, .io multiplayer — monetize best with rewarded video and interstitials on a portal. Retention-heavy genres like puzzle games can layer cosmetic IAP or a season pass on top.

Highly polished single-player titles can attract sponsors or flat-fee licensing through distributors. Casual mass-market builds aimed at the casual category often live entirely on portals where ad RPMs are stable but ceilings are capped.

There is also a structural choice: self-hosted versus portal. Portals lower distribution friction; self-hosting raises the revenue ceiling but loads marketing onto you. Verdict: "Portal revenue share is the fastest path to first-dollar income.

Self-hosted ads have the highest ceiling but require you to bring the traffic yourself." Publish on Poki or CrazyGames by integrating their developer SDK (loading events, gameplay start/stop, interstitial and rewarded ad calls), submitting through the developer portal, and…

Both pay revenue share. CrazyGames' developer terms describe the rights as non-exclusive by default, with optional per-title exclusivity if the developer agrees. Poki's HTML5 SDK exposes a small JavaScript API.
