About this tool
Endless runner game online free — jump and duck past obstacles as the speed keeps climbing.
Dino Dash Runner is an endless runner where you jump pillar clusters and duck under hovering drones while the world accelerates from 330 to 800 pixels per second over your first 3,200 points. Holding the duck key in mid-air multiplies gravity by 2.2 for a fast fall, which is the move that saves you when a low drone appears right after a jump. The palette flips between day and night every 500 points, sound is off until you switch it on, and your best score is kept in this browser.

Holding duck while airborne accelerates the descent 2.2×, so a mistimed jump is recoverable instead of fatal.
Both the player and each obstacle are inset by several pixels before collision is tested, so near-misses read as near-misses rather than cheap deaths.
The record is stored locally per game, so it survives a reload — nothing is uploaded and no account is involved.
Space, the up arrow or W jumps; the down arrow or S ducks on the ground and fast-falls in the air; P pauses. On touch devices the two buttons under the canvas do the same, and holding the duck button works exactly like holding the key.
At 350 points, after which roughly a third of spawns are drones instead of ground pillars. They hover at two heights — the low one, 44 pixels above the ground, has to be ducked or cleared with a well-timed jump, while the high one at 96 pixels can be run straight under.
Speed ramps linearly from 330 pixels per second at the start to a maximum of 800 at 3,200 points, and stays there. The spacing between obstacles scales with speed too — the minimum gap is 250 pixels plus half the current speed — so the pressure is timing rather than an ever-shrinking window.
