Dolmuş

Highlights

• A shared taxi, not a race. Stop at the stops, open the door, let passengers off (they pay) and new ones on; each one tells you where they are going in a chat bubble, and the 12 seat chips show who gets off where. Press Play and you are driving after a 3-2-1 countdown, with the first stop coached by a pulsing ring.
• "Müsait bir yerde!" (v2). From level 2 about a third of the passengers just ask to be dropped anywhere safe near their stop: pick a legal curb within 70 m and press Space. Crossings, junctions, signal queues and the oncoming lane are refused; a spot close to them earns a penalty and a honk, a good one an "easy stop" tip.
• The fare chain (v2). Fares are passed forward along the occupied seats, one hop per row, and the door waits for the last coin; pull away early and you lose that tip.
• Tips for good driving. Fast and smooth rides earn tips; red lights, crashes, hard braking with passengers on board and skipped passengers cost you, and at 100 % dents the shift is over.
• Eight shifts and an endless mode. New routes, a tram and buses, rain, a double-parked van, narrow streets with a VIP passenger, a traffic jam, the ferry pier, the evening rush and a night shift.
• A living street. Traffic follows lanes and lights, pedestrians cross at zebras, the tram obeys its signals, and pigeons scatter at the horn.
• Balanced by a bot. The ?auto bot drives with the same controls and rules as a player and finished all 8 levels; the star thresholds were calibrated against it.
• Light on a laptop GPU. About 60 fps (the vsync cap) on an Intel UHD 630 laptop at 1280x720 with 42 draw calls on the High tier, and a ?low tier for phones (measurements).
• One file, made in code. One index.html with Three.js r170 from a CDN; the base game is procedural, with an optional CC0 asset pass loaded on top.

How to play

[!TIP] Goal: a shift lasts 4 minutes. Drive the fixed route (6 to 10 stops, numbered on the minimap) and earn as many Turkish lira as you can; 1 to 3 stars depend on your net total versus the level target.

Waiting passengers wave when you get close. Press Space within about 13 m of a stop (or of a waving passenger): the dolmuş brakes to a halt and opens the door. Passengers get off first and pay, then new ones board and tell you their stop (chat bubble, numbered seat chip, green ring and light beam at the destination). A chip with a ? is an "anywhere" rider: on the minimap their destination is a 70 m green stretch of the route, and any safe curb inside it will do.

• Tips reward fast rides (the shrinking patience bar on the seat chip shows the expected time) and smooth rides (no hard braking, no crashes while they are on board). VIP passengers pay triple but have little patience.
• Penalties: running a red light, hitting cars (also raises the dent meter), hard braking with passengers on board, skipping a waving passenger when you have a free seat, hitting a pedestrian, and passengers who give up waiting. At 100 % dents the dolmuş is wrecked and the shift ends.
• A full dolmuş accelerates noticeably slower. Rain makes the road slippery and fills the stops with people. Pigeons, pedestrians, a tram, buses and a double-parked van are all part of the traffic puzzle.

4	Narrow streets	side streets with cars parked on the pavement, the mosque square, VIP passenger
5	Gridlock	traffic jam event on the main street, rain
6	The ferry pier	sea road and ferry pier stop, 9 stops

Controls

Action	Mouse / touch	Keyboard
Accelerate	gas pedal	W / Up
Brake, reverse	brake pedal	S / Down
Steer	steering slider	A D / Left Right
Stop and open the door	door button	Space
Horn	horn button	H
Pause	pause button	P / Esc
Music / effects / language	HUD buttons	M / X / L
Minimap: heading up / north up	tap the minimap	N

A gamepad works too: RT / A accelerate, LT / B brake, the left stick steers, X opens the door, Y is the horn, Start pauses.

Settings are saved in localStorage under arena.dolmus.settings; best scores, stars and the run you can continue under arena.dolmus.save. The language follows the browser (Turkish when the browser language starts with tr, English otherwise); the toggle and ?lang= override it.

Flag	Effect
?auto	a real driving bot plays the whole campaign (same controls and rules as a player)
?debug	fps, draw calls, triangles, state, bot results and JS errors on screen; window.dolmusSim(seconds) fast-forwards
?sim=N	fast-forward N seconds of the first shift before the first frame (add &auto to let the bot drive)
?low	shadows off, pixel ratio 1, half the particles, procedural models, no textures or sky
?noassets	skip every optional asset (models, textures, sky, sounds) and run the procedural game
?assets=models,tex,sky,snd	load only the listed asset groups
?nocamfix	turn the chase-camera obstacle avoidance off
?lang=en / ?lang=tr	language
?level=N	start the campaign at level N
?mode=endless	with ?auto or ?sim, start in endless mode
?seed=N	gameplay random seed (default 7)
?touch	force the touch controls
?cam=tram, van, bus, mosque, pier, bridge, plaza, main or x,z	spectator camera (camd, camh, cama adjust distance, height, angle)
?cal	with ?auto: advance to the next level whatever the result (used to calibrate the targets)

The live state is on window.dolmus (state, level, time, net, score, seats, dent, finished shifts, errors). Example: index.html?auto&debug&sim=3000 plays the whole campaign in a few seconds without rendering.

Screenshots

Balance

The simulation runs at a fixed 60 Hz step and does not need the renderer, so ?auto&sim=4000 plays the whole campaign without rendering. With assets, with ?noassets and with ?low it gives the same result: levels 1 to 8 finished, with stars / net lira 1: 2/306, 2: 1/254, 3: 2/282, 4: 3/402, 5: 2/272, 6: 2/344, 7: 3/459 and 8: 3/478 (after one retry), and no JS errors (verification run).

Running locally

Serve the folder over HTTP (opening index.html directly also works in most browsers, but then the optional assets do not load and the game stays procedural):

python -m http.server 8000

then open http://localhost:8000/.

How it was made

Built by Claude Sonnet 5.5 with Claude Code from one prompt: prompts/dolmus.md. The base game is fully procedural: about 300 buildings, roads, trees, the mosque, bridges and the pier are merged low-poly geometry with vertex colours; cars, buses, the tram, pedestrians and pigeons are instanced. The engine, horn, rain, tram bell, street ambience and the arabesk-pop style tune in Hicaz are synthesised with the Web Audio API.

An optional asset pass (about 1.13 MB) adds Blender-built low-poly vehicles and props (the dolmuş with its sliding door, cars, buses, the tram, the van, stop shelters, simit and chestnut carts), Poly Haven detail textures and sky, and Kenney sounds for the door, coins, crashes and clicks. They load after the first frame, only on the High tier (sounds on both), and the procedural versions stay as the fallback (?noassets skips them). Licences: CREDITS.md; file list, sizes and fps before and after: docs/assets.md. Model scripts: assets/src/.

Dolmuş is part of the Claude Game Arena series, where each game is built by a Claude model from one prompt. The other games: Hisar · Çay Ocağı · Çini Ustası · Martı · Kervan · Peri Golf · Mehter · Boğaz Vapuru · Simit Fırını · Karagöz · Lale Bahçesi

Round 5: Kapadokya Balonu · Ebru · Kırkpınar · Çarşı Kaçışı

Round 6: Topkapı Gecesi · Hamsi · Pamukkale · Mimar Sinan

v2 update

Upgraded by Claude Sonnet 5.5 with Claude Code from prompts/dolmus-v2.md:

• Play starts the shift after a 3-2-1 countdown; the first stop is coached with a pulsing ring and an arrow. The language follows the browser.
• "Anywhere" riders (from level 2): drop them at any safe curb within 70 m; crossings, junctions and signal queues are refused.
• The fare chain: coins hop forward along the occupied seats and the door waits for the last one.
• 24 passenger lines per language by passenger type, with a no-repeat window (12 boardings in a row are all different).
• A shift summary that names the two costliest mistakes with a one-line tip, the best tip and the anywhere drops.
• District identity (Balat, Galata / Karaköy, Kadıköy pier), shop awnings, umbrellas and puddles in rain, lit windows and stop-shelter glow at night, and the white Turkish Van kitten on the summary card.

Türkçe

Dolmuş, alçak poligon İstanbul tarzı bir mahallede geçen 3D arcade sürüş oyunu. Sarı dolmuşla el sallayan yolcuları al, balondaki durağı öğren, yolcuyu indir, ücret ve bahşiş topla; kırmızı ışıktan ve kazadan uzak dur. Sekiz vardiya ve sonsuz mod var: tramvay, yağmur, VIP yolcu, trafik sıkışıklığı ve gece vardiyası. Kurulum yok; masaüstünde ve telefonda tarayıcıda oynanır. Claude Sonnet 5.5 tarafından Claude Code ile tek bir prompt'tan yapıldı.
