Steer two cars at once. Tap left half to switch the blue car's lane, right half for the red car. Catch squares, dodge circles.
The screen is split into two halves, each with two lanes and one car. The blue car runs on the left half, the red car on the right.
Tap (or click) anywhere in the LEFT half to switch the blue car between its two lanes. Tap anywhere in the RIGHT half to switch the red car. Each tap toggles that car between its two lanes. On desktop, A/D switches the blue car, J/L switches the red.
Objects scroll down from the top:
• Squares = collect. Your car MUST be in that lane when the square arrives. Missing a square ends the game.
• Circles = dodge. Your car must NOT be in that lane. Hitting a circle ends the game.
Speed ramps up the longer you survive. Score = squares collected across both cars. There is no time limit — the game ends only when you miss a square or hit a circle.
The hardest part isn't a single car — both cars are easy alone. The skill is parallel attention. Don't focus on one half at a time; widen your gaze so both halves are in peripheral vision and your hands respond to whichever side has the nearer object. If you find yourself tunnel-visioning on one car, you're about to miss something on the other.
Prefer the lane your next object is in. The car has no penalty for staying in a lane, so anticipate: if a circle is coming in lane 0, switch to lane 1 EARLY and stay there until the circle passes. Last-second switches at high speed lead to miscounts when both cars demand attention.
Watch for the dangerous double — a square on one side AT THE SAME Y as a circle/square on the other. These force simultaneous decisions. The instinct is to handle the closer side first, but actually handle the side whose lane needs to CHANGE (square in the other lane than your current, or circle in your current lane). The side that's already correctly aligned needs no action.
Speed amps gradually but ramps hard above score 50. The early game is just warm-up; train yourself to widen peripheral vision before the speed climbs. Most players die above 80 not because they can't see the object but because they decided too late.
