I HAVEN'T WRITTEN A LINE OF GAME CODE SINCE FABLE 5.1 SHIPPED I used to think making a browser game meant Unity, a team, three months, and an asset artist -> now I write a SPEC.md, hit /model fable-5 in Claude Code, and a playable HTML5 build lands in the folder while I make coffee here's what's actually inside the folder that replaced the studio: • the spec: > SPEC.md - genre, mechanics, both desktop AND mobile controls, 16:9 aspect ratio, <8MB load, no external requests, incognito-safe localStorage > portal requirements baked in on day one so nothing gets redone at review • the game: > game.js - the only file that matters. written once, never edited between portals > index.html - local dev entry, Ads stub logs to console and resolves reward=true > assets/ - relative paths only. no CDN, no Google Fonts, nothing that phones home • the ad abstraction (this is why one codebase ships to both portals): > Ads.loadingFinished() - assets ready > Ads.gameplayStart() - fires on FIRST INPUT, not on load. Poki checks this > Ads.gameplayStop() - any pause, death, menu > Ads.interstitial() - between runs > Ads.rewarded() - continue after death, double the score • the portal entries (game.js does not change): > poki.html - loads poki-sdk.js, wires Ads to PokiSDK.commercialBreak / rewardedBreak, prevents parent-page scroll jump on arrows and space > crazygames.html - loads crazygames-sdk-v3.js, wraps requestAd callbacks in Promises, grants reward ONLY inside adFinished • the funnels: > Poki: upload -> Playtesting -> Player Fit Test -> Web Fit Test -> Final Review. failed Web Fit usually means new icon and title, not new game > CrazyGames: dev account + Tipalti payment onboarding BEFORE submit, or the game button stays greyed out • the economics: > RPM $2 weak / $4 normal / $6-8 strong > $15,000 = 2 to 7 million sessions > Poki has 90M players/month. CrazyGames has 300M sessions/month > 2 months CrazyGames exclusivity raises the share by ~50% 1 game.js. 3 entry files. 2 portals. 0 lines of duplicated logic nothing in there is clever. every file exists because a portal once rejected a build for calling an external CDN and I wrote the rule down instead of remembering it Fable 5.1 doesn't ship the game. the folder does
