Reflex Run

Race forward and steer into the lane with the correct answer before the gate arrives.

How to play

You run automatically down a multi-lane track. Each gate poses a math fact with a different answer in each lane — swerve into the lane holding the right one. Correct answers speed the track up for a bigger challenge; a miss loops the fact back around so you can try again.

• Read each gate's problem and pick the correct lane in time.
• Right answers accelerate the track and raise your score.
• Misses send the fact around again as practice.
• Keep going as long as you can — it is an endless sprint.

Controls

• Desktop: steer with ← → or the A and D keys.
• Phone & tablet: tap the left or right side of the track to swerve into that lane.

Game modes

• Daily seeded track or endless Practice, at Easy, Medium or Hard.

Tips & strategy

• Solve the fact as the gate appears, not when it is on top of you — the faster track punishes hesitation.
• Commit to a lane early and hold it rather than weaving between two.
• Use Easy to build speed and fact recall before stepping up the difficulty.
