Experimental Design Variable Dash

Run as far as you can

Your runner never stops. Dodge what is in your path and your score keeps climbing.

• Score comes from distance, coins and quiz bonuses.
• The game gets faster every 450m.
• The scenery changes every 450m: snow, beach, night, then back to the meadow.
• Your best score is saved on this device.

Move in three lanes

• Left / Right (or A / D): change lane
• Up, W or Space: jump
• Down or S: duck
• On a phone, swipe in any direction or use the buttons under the game.

Obstacles

• Brown block: jump over it.
• Red gate: duck under it.
• Purple wall: switch lanes. Only a moon jump clears it.
• Hitting one ends your run unless you have a shield.

Power-ups

• Shield: absorbs one hit.
• Slow-mo: slows the world for 6 seconds.
• Double points: 8 seconds.
• Moon jump: floaty, very high jumps for 8 seconds.

Checkpoint questions

Every 150m the game stops and asks a question.

• Right answer: +150 points and you keep going.
• Wrong answer: you are knocked back 50m, lose that much score and lose your shield.
