Quadline Trials
Throttle, brake, lean. Keep a quad on four wheels over 30 tracks and race your own ghost.
Quadline Trials puts short 3D quad-bike courses on your phone with direct throttle, brake and lean controls. Hold throttle with one finger and lean with another. Raise the nose before a climb, lower it for a landing, or brake to get control back. Held buttons light up, checkpoint flags change color, and a progress strip keeps the finish in view. There are thirty terrain layouts across six landscape palettes, from the quarry run to the coastal ridge. Each attempt gets three minutes, a crash ends it, and cleaner, faster finishes score more. Earn campaign medals, ride any track in open practice, or come back for the dated daily challenge. Your fastest clean finish saves a local ghost to race next time. Tokens unlock quad color tints that change looks, not performance. Offline, no account, in English, Spanish or Brazilian Portuguese. Free with ads at attempt breaks. An optional video can restore your last checkpoint, but that run is marked assisted and earns no records.
