Simit Fırını

Highlights

• A full production chain. Five stations (kneading, shaping, molasses, sesame, oven) staffed by workers who gain skill; an unstaffed station runs at 30 % because the owner fills in, but an unattended oven burns the bread.
• Simit sellers on the street. Simitçi carry trays to street spots, sell by the hour and walk back to refill; demand follows the hour and the weather (rain empties the park and the pier, cold fills the tea houses).
• Plan the day, then open the shop. Set production targets and prices, order ingredients, hire staff, buy upgrades and take contracts before each day.
• More than simit. Poğaça, açma, çatal and pide unlock over time.
• Hands on in 3D. Drag a worker onto a station or a street spot in the scene; click a label to open its panel with sales and demand charts.
• Balanced by a bot. A sensible bot wins in roughly 9 of 12 seeds (between day 16 and 20); a careless one goes bankrupt around day 7.
• One file, made in code. One index.html with Three.js r170 from a CDN; geometry, textures, music and sound effects are all generated in code.

How to play

[!TIP] Goal: 5,000 lira in the till and 4 stars of reputation by day 20. Afterwards you can keep playing in endless mode.

Each morning, plan the day (production and prices, supply, street, staff, growth), then press Open the shop. Staff the stations, keep an eye on the oven and send simitçi out to the street spots where the demand is.

• Production chain: flour and water, knead the dough, shape the rings, dip in molasses, roll in sesame, bake, racks.
• An unstaffed station runs at 30 % (the owner fills in), but an unattended oven burns the bread.
• Simitçi carry trays to the pier, the school, the park, the office and the tea houses, sell by the hour and walk back to refill. Demand follows the hour and the weather.
• Wages, rent and wood are paid at night. Go below zero and you are bankrupt.
• Recipes unlock over time: poğaça, açma, çatal, pide.

How it was made

Built by Claude Sonnet 5.5 with Claude Code from one prompt: prompts/simit-firini.md. Everything is generated in code: the cut-away bakery, the street, the workers and customers, the textures, the music and the sound effects. No asset files are used; Three.js and the Fredoka and Nunito fonts load from CDNs, see CREDITS.md.
