COASTER LAB

🎢 섬 위에 나만의 롤러코스터를 짓고, 타고, 평가받으세요.
🎢 Build, ride and get rated on your own roller coaster — on a toy-diorama island.

COASTER LAB은 브라우저에서 바로 하는 3D 롤러코스터 설계 게임입니다. 리프트 힐을 올리고, 낙하·루프·코르크스크류를 이어 붙이면 역으로 돌아오는 길은 자동으로 이어집니다. 다 지었으면 맨 앞자리에 앉아 직접 타 보세요. 흥미도·강도·멀미 점수와 G 그래프, 손님들의 한마디가 기다립니다.

COASTER LAB is a 3D roller-coaster design game that runs right in your browser. Raise a lift hill, chain drops, loops and corkscrews — the track back to the station builds itself. Then take the front seat and ride it. Excitement / intensity / nausea ratings, a G-force graph and your guests' reviews are waiting at the end.

✨ Features

• Campaign — 10 stages on 5 islands. Meadow, hills, lake, canyon and mountain, each with a budget, objectives (top speed, airtime, inversions, over-water and tunnel runs, intensity and nausea limits) and 1–3 stars.
• Real coaster elements. Vertical loops, corkscrews, heartline & zero-G rolls, Immelmann, dive loops, airtime hills, helices, LSM launches and trim brakes — built along a proper heartline with physically simulated G-forces.
• Easy builder. Ghost preview (green = OK, red = why not), parameter chips with recommended sizes, auto return to the station, automatic tunnels when you dig below ground, undo/redo, edit any piece.
• Ride it. Lap bars, gates, "Go!", then front seat, rear seat, chase and cinematic cameras, speed lines and G tunnel-vision. Rollbacks and overruns happen if you get it wrong.
• Ratings like the classic tycoon games. Excitement, intensity, nausea, a front/rear vertical-G graph with safety limits, highlights and guest comments.
• Sandbox. Any island, any time of day (night included), box / truss / tubular track, your own colours, three showcase presets, a random coaster button, share links and JSON export.
• A living park. Forests, food stalls, lamp posts, guests who cheer when your train rushes past, procedural music and sound.
• Tiny and ad-free. Everything — terrain, trees, people, music — is generated in code.
• 한국어 / English.

🎮 Controls

• Build: 1–9 pick a piece · Enter place · Backspace delete · Z / Y undo / redo · Space test ride · F focus · Esc pause
• Camera: right-drag rotate · left-drag pan · wheel zoom · WASD move · Q / E turn
• Ride: C change camera · T telemetry · drag to look around · Esc back to building

💡 Tips

• Match loop and roll sizes to your speed — the chip with a green dot is the recommended size.
• Airtime is the moment you float out of your seat over a hill. Guests love it.
• Over budget? You can still test-ride, but no stars.

🖥 Requirements

Desktop Chrome, Edge or Firefox with WebGL2, keyboard and mouse. Not made for phones. If it stutters, the game lowers its graphics quality by itself (or pick one in Settings).
