Dino Runner

Overview

Run right, jump the cacti, duck the birds. That is the loop that millions of people first met on Chrome's offline network-error page, and it holds up as a genuine game rather than a placeholder because the difficulty actually ramps the longer you survive. The world is an infinite side-scroller: obstacles spawn procedurally, the scroll speed increases over time, and the only inputs that matter are jump, duck, and the double jump you can trigger mid-air for extra distance. Two obstacle types define the run — low cacti you clear with a jump, and the flying birds that arrive at head height, which you either duck under or time a jump past. At five hundred points the screen flips to night mode, a small visual reward that doubles as a progress marker. Scores are saved locally, so there is always a number to chase.

How to Play

Press Space or the up arrow to jump; double-tap Space for a double jump that extends your airtime when you misjudge a gap. Press the down arrow to duck, which shrinks your hitbox to slip under low-flying birds. On touch, tap to jump and swipe down to duck. The mouse option is a click to jump. The dino runs automatically — your only job is deciding when to leave the ground and when to tuck. Obstacles arrive at a fixed cadence per speed tier, so once the screen accelerates the jumps come faster without warning.

Tips & Strategy

Learn the double jump's window. It is not a separate move you save for emergencies — it is the cleanest way to clear back-to-back cacti or recover from a jump you took too early, so practice the timing on flat ground before you need it. For birds, judge by height, not distance: a bird at head height means duck, a bird at jump height means hop over it, and guessing wrong is the most common death past a few hundred points. Stay calm as the screen speeds up. The obstacle types do not change, only the spacing shrinks, so the patterns you read at slow speed are the same patterns, just tighter. Use night mode at five hundred points as a checkpoint — if you can hold your line through the dark stretch, your reflexes have settled in.
