How to play

One finger, four swipes

Your first run comes with a tutorial that pauses until you make each move.

Switch lanes

Swipe left or right.

Jump

Swipe up to clear the fences.

Slide

Swipe down to get under the signs.

Hop on the train

Run up the ramps to the roofs: there are more coins up there.

Three worlds

The scenery changes every 1,000 meters

Each world has its own music and an obstacle you only find there.

World 1 Rail Critters screenshot: the fox runs through the meadow among trees and bushes.

The meadow

Where it all begins: trains, fences, signs and the first ramps.

World 2 Rail Critters screenshot: the desert with cacti and a ×2 combo on screen.

The desert

Cacti, heat and tumbleweeds that roll from one lane to another.

World 3 Rail Critters screenshot: the night forest with pines, stars and the moon.

The night forest

Pines, lampposts and logs that block two lanes at once.

Your gang

Six characters, six styles

Play as the kid, the cat, the dog, the fox, the panda or the axolotl, and mix them with a T-shirt, hoodie, jersey, ninja outfit, the caped legend outfit or the luchador suit. Almost everything is bought with the coins you earn running; what carries a star (★), the axolotl and the luchador suit, is a shop exclusive that only changes how you look.

The shop

Everything is earned by running. The exclusives, if you want to support us

Coins are never sold and nothing you buy makes you stronger. The exclusives only change how you look, you buy them once and they are yours on every phone with your account.
