Owner

CrazyGames games can now select a dedicated HTML5 web target instead of inheriting browser-preview behavior. The existing browser adapter exports /crazygames, initializes the official v3 SDK, reports loading and playable scene activity, and observes interstitial presentation through the common advertising contract. Basic Launch disables monetization; Full Launch enables catalog-configured midgame interstitials. Rewarded ads and IAP remain unavailable pending independent backend verification.

Game-owned gameplay scopes preserve scene, lifecycle, and native presentation ownership. Host muteAudio settings own an independent audio block, and focus-only changes do not duplicate CrazyGames gameplay events. Both the private starter and generated starter include the target and enter free play directly. Target build/smoke verifies relative index asset paths and upload size/file limits; portal approval and live-device acceptance remain game-owned.

Validation: pnpm check; 74 focused browser/runtime/Phaser tests; catalog, ad, target, effective-config and platform-target validation; local OCR review of all 56 changed files, including default exclusions (100% coverage, no skips). pnpm build:crazygames and pnpm smoke:target crazygames passed. A real Chromium run with an SDK fixture confirmed loading-start → loading-stop → gameplay-start and direct playable scene entry; aborting the SDK script still produced a playable canvas with no uncaught runtime error. Live ad delivery and developer-portal approval are not certified by this fixture. pnpm test:workspaces, target-artifact tests, docs-example type checks, package export/tarball validation, and a standalone generated consumer type check/build passed. CI now builds and smokes CrazyGames explicitly. Includes a Sampo changeset for the six directly changed public packages; no new npm package or initial-publish registration is needed.

The SDK advertising contract is verified against official requirements: adError is a terminal resume observation, including other, and the additive AdProvider.presentationAudio policy defers CrazyGames audio blocking until native start. Existing providers retain requested-time audio by default. Native uncertainty still quarantines ownership until an observed terminal callback. Regression coverage includes load rejection, errors after start, late callbacks, deferred audio, reentrant cleanup, and independent background/settings ownership.

📝 Walkthrough

Walkthrough

This change adds CrazyGames as a non-installable web target. It introduces a browser SDK adapter with launch-dependent interstitial support, runtime loading and gameplay reporting, Phaser starter integration, and CrazyGames-specific target configuration and artifact checks.

Changes

CrazyGames target

Layer / File(s) Summary
Target contracts and capabilities
packages/platform/src/index.ts, packages/target-config/*, tools/target/schemas.ts, tools/target/platform-targets.ts, tools/target/effective-config.ts
The platform and target configuration add the crazygames-web runtime, crazygames release profile, integration bounds, and optional crazyGamesLaunch metadata. Effective configuration disables IAP, subscriptions, banner ads, and rewarded ads. Interstitial ads require Full Launch and enabled interstitial and monetization settings.
CrazyGames browser gateway and ads
adapters/browser/src/crazygames.ts, adapters/browser/src/crazygames.test.ts, adapters/browser/src/index.ts, adapters/browser/package.json, packages/catalog/placements.json, tsconfig.base.json
The browser adapter loads and initializes the SDK, exposes lifecycle, activity, and audio settings, and supports interstitial presentation for enabled Full Launch configurations. Tests cover initialization, availability, callback sequencing, idempotency, and uncertain presentation outcomes.
Game activity and scene scopes
packages/game-runtime/src/game/*, packages/game-runtime/src/phaser/*
The runtime adds gameplay scopes, reports loading and gameplay activity, and applies host audio mute state. Phaser scene pause, resume, sleep, wake, and disposal update the associated gameplay scope.
Build target and generated starter wiring
packages/cli/src/*, examples/phaser-starter/*, packages/cli/templates/phaser-game/*
The CLI and Phaser starters recognize the CrazyGames target, configure its gateway and launch mode, and route free-play launches directly to gameplay. Starter target manifests and workflow guidance include CrazyGames.
Artifact validation and release support
tools/target/crazygames-artifact*, tools/target/build-target.ts, tools/smoke/*, package.json, .github/workflows/ci.yml, docs/CRAZYGAMES.md, README.md, .sampo/changesets/crazygames-target.md
Build and smoke flows add CrazyGames artifact checks for file count, total size, entry types, and root-relative or remote asset paths. Build commands, CI, documentation, and release metadata include the target.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Clear the cached initialization promise after init() fails.

sdkInitialization keeps the rejected init() promise for the SDK object. After one failed initialization, every later gateway gets the same rejection and turns the SDK off for the rest of the session. The timeout rejection is a separate case: the cached promise can still resolve later, so it does not need to be cleared.

Delete the entry when the promise rejects:

Proposed fix
-      initializing = Promise.resolve().then(() => candidate.init());
+      initializing = Promise.resolve().then(() => candidate.init());
+      initializing.catch(() => { sdkInitialization.delete(candidate); });

Review comments at @adapters/browser/src/crazygames.ts:
- Around line 82-83: Update the failure branch in loadCrazyGamesSdk to delete
the document’s entry from sdkLoads and remove the failed script element before
rejecting, allowing later calls to retry without leaving timed-out scripts in
the document.

Review comments at @tools/target/crazygames-artifact.ts:
- Around line 27-30: Update the asset URL validation loop using `index.matchAll`
so it also detects unquoted `src` and `href` values, rejecting root-relative and
absolute HTTP(S) URLs just as it does for quoted values. Add an unquoted URL
case to the CrazyGames artifact tests in `crazygames-artifact.test.ts`.
