Publish a game

Automated checks before you submit

After you submit, the platform automatically checks your uploaded files and lists any issues below — fix them as prompted and resubmit. The results are saved with your work, so you can revisit them anytime with “Review pre-check results”.

Using platform capabilities

This section applies to single-file HTML and web bundles, which run on-site. Download works skip it.

The game runs inside a platform-provided iframe shell: the top bar (Back to Yonest / Leaderboard / Restart / Fullscreen) is provided by the platform, and no platform code is written into your HTML file. When you need platform features, just add optional guarded calls like these:

What the platform gives your game

• Top bar and navigation (Back to Yonest, leaderboard, restart, fullscreen) come from the platform — you don’t build them.
• A “Back to Yonest” button in your game-over dialog: one call, styled to match.
• Score reporting and leaderboards, with each player’s all-time best and own rank (leaderboard-enabled games only).
• A dictionary table in up to 8 languages: register once, the UI follows the player’s language.
• Player identity (display name and id) for greetings and personalised content.
• A game-scoped login token, so your own backend can verify the player’s identity and entitlement.
• Fully removable: without the platform these calls are skipped, and exports can strip the hooks in one go.
• Local mock and TypeScript types: test the integration without the platform, and get a typed window.Yonest.
• Pause / resume / fullscreen / before-leave events, so timers and saves follow what the player does.
• In-game event counts (Yonest.track) with a one-click CSV export in the Maker Console.
• Cloud saves (Yonest.save): progress follows the account across devices; 20 keys per player per game, 32KB each.
• Achievements (Yonest.achievement): unlock records are stored by the platform; idempotent, so no duplicates.
• Daily and weekly boards (UTC) alongside the all-time best — nothing extra to build.

/* yonest:start */
if (window.Yonest) window.Yonest.gameOverActions(resultEl); // add "Back to Yonest" to the game-over dialog
if (window.Yonest && window.Yonest.supportsLeaderboard) {
  window.Yonest.submitScore(score);                        // submit a score (leaderboard-enabled games only)
}
// window.Yonest is injected after the iframe loads: queue init calls, they replay on install
(window.YonestQueue = window.YonestQueue || []).push(function (Yonest) {
  Yonest.i18n(dictionaries, 'en');                          // required: register your dictionaries (don't skip this)
  Yonest.applyI18n();
});
/* yonest:end */

Without window.Yonest these calls are skipped automatically, so the game still runs fine outside the platform.
