About DELUGE 40 — 40일의 대홍수
DELUGE 40 is a free browser game based on the story of Noah's ark in Genesis. Animals crowd the screen while the flood rises; you pick two (later more) of the same animal and tap a room on the ark to put them aboard, which lowers the water. Predators cannot share a room with their prey (the lion with the giraffe, cow and pig; the fox with the chicken and frog), rooms fill up and have to be extended a limited number of times, animals already under water cannot be chosen, sea turtles can be released into the water instead, and from day 10, 20 and 30 you can select more animals at once. Survive to day 40 and the rain stops, and you send out a dove to look for dry land. There is a 2× speed mode worth 1.5× points, and an optional Google sign-in for a leaderboard. The developer, 긱코드, made it in a GPTers vibe-coding study group: they say they could not code, made the first version (a pair-matching memory game turned into this flood action game) with Claude Code in a day, and in the second week added a storm intro, AI-generated sprite animations, CC0 sound effects and the ranking, still without typing any code. In Korean.
How it was built
Partially verifiedIn the week-1 GPTers post (27 Jul 2026, Korean) the developer, who says they did not know how to code, lists the tool as Claude Code (vibe coding in the terminal by asking in words) and the model as Claude Opus 4.8, and writes that they did not type a single line of source code: everything was done by asking it to make or fix things. The game started as a card-flipping pair-matching game and became a flood action game after the developer asked Claude Code for ideas to make it more game-like. The week-2 post (4 Aug 2026) says the code for the title intro, sprites and sound was again all done by asking in words, with zero lines typed by hand.

Made in the 23rd cohort of the GPTers game vibe-coding study, where each week's assignment moved the game forward. Week 1: a first playable version in about a day (half a day of focused work), deployed on Vercel. Week 2: a “tap the screen to start the storm” intro, sprite animations of the lion and giraffe generated with an AI image pipeline, CC0 sound (rain and thunder by CluckFox, Kenney RPG Audio effects, animal sounds from OpenGameArt) credited in a CREDITS file, a mute button, predators, room placement and a day/night cycle, and a Google sign-in leaderboard on Firebase. The game is a single web page.

“소스코드는 직접 한 줄도 안 씀. 전부 "이렇게 만들어줘 / 이건 이렇게 고쳐줘"로 진행”- Week 1: making Tetris and a Noah's ark game without knowing how to code (GPTers, Korean)
- Week 2: title, images and audio with Claude Code (GPTers, Korean)
Verification notes: AI use and development steps come from the developer's two GPTers posts, re-read on 6 Nov 2026 (publication times in the page data: 27 Jul 2026 07:56 UTC and 4 Aug 2026 03:13 UTC). Claude Opus 4.8 is quoted as the developer gives it. Gameplay comes from the live game's own rules screen (title “DELUGE 40 — 40일의 대홍수”), read on 6 Nov 2026; the name DELUGE 40 is not used in the posts, which call it the Noah's ark game, but the posts link the same address. The release date is the week-1 post, which says the game was already deployed. The page's scripts make no calls to AI services; the leaderboard uses Firebase. The story is from Genesis (public domain). A Tetris clone on the same site is a separate work and is not listed here. Team size and location are not stated. The game was not played.
