T-Rex Game Ducking Guide — Tips & Guide (2026)
Master the Down Arrow to Survive Longer and Score Higher
Down Arrow has two source-backed uses in desktop Chrome Dino: it ducks the running T-Rex and triggers speed drop while airborne. Duck the middle y=75 pterodactyl, jump the lowest y=100 bird, and keep running under the highest y=50 bird. Current mobile Chromium omits the duck-required middle position.

When and Why to Duck
Duck the Middle Desktop Pterodactyl
BeginnerHold Down Arrow for the y=75 bird. Its collision boxes cross the standing dino while the ducking box fits below.
Jump Cacti and the Lowest Bird
BeginnerCacti and the y=100 pterodactyl occupy the lower part of the playfield, so ducking does not clear them.
Use Down in the Air for Speed Drop
IntermediateWhile airborne, Down Arrow sets the speed-drop state, sets jump velocity to 1, and multiplies vertical displacement by the configured coefficient of 3. Use it when the next visible obstacle makes an earlier landing useful.
Duck Timing and Duration
Hold Until the Middle Bird Passes
BeginnerKeep Down Arrow held while the y=75 pterodactyl's collision boxes overlap the dino's horizontal position, then release so the runner can jump again.
Do Not Duck the Highest Bird
AdvancedThe y=50 pterodactyl already passes above the standing T-Rex. No input keeps you ready for the next obstacle.
Release Down After Speed Drop
IntermediateIf Down remains held when the dino returns to ground, Chromium converts the speed-drop state into ducking. Release it when an immediate ground jump is needed.
Advanced Duck Applications
Combine Actions Only After Reading the Sequence
AdvancedA cactus followed by the middle bird may call for jump, speed drop, then continued Down to duck. Confirm the rendered sequence before committing.
Treat Fast-Fall as a Recovery Option
AdvancedSpeed drop can shorten an overlong jump, but using it too early can also cause a collision. Base it on the next obstacle.
Treat The Jumping Dino Separately
IntermediateThe Jumping Dino app includes flying enemies and its own touch-first physics. Use it for additional runner practice without assuming its duck timing or hitboxes are identical to Chromium.
