Stair Race 3D is a race where the track is the thing you're carrying. You run forward collecting stair segments, then lay them down to climb over the obstacles and gaps in your way — and your rivals are doing the same, so hoarding steps and spending them well is the whole strategy.
It's short, colourful and immediately readable, in the mould of the hyper-casual runners that dominate mobile. The final climb at the end of each level decides the placement.
Arrive at the final staircase with the biggest stack of steps. That means collecting greedily along the route and avoiding obstacles that knock segments off — spending them on unnecessary gaps costs you the finish.
You race computer-controlled rivals in short levels rather than live players.
