SCORING INFORMATION

For each level, beat the target score to earn a medal (Bronze, Silver, Gold)

• Target score >>> 3000-5999 points (B), 6000-8999 points (S), 9000+ points (G)

Scoring calculation

The score is calculated as follows:

BASE SCORES

• 10 points per correct answer
• 20 points per correct answer
• 40 points per correct answer
• 80 points per correct answer
• 160 points per correct answer

DIFFICULTY MULTIPLIER: The multiplier is located in the top UI of the game. Players move up a difficulty by getting 3 correct and move down a difficulty by getting 2 incorrect.

DISTANCE: Points are awarded for the distance a robot has travelled. Robots travel from the right to the left of the screen. The greater the distance they travel the more points they gain, up to a maximum of 100 points.

BONUSES: For the three most difficult robots (monocycle, spider and tank), you get a bonus 3,000 points for the first time you answer a question for a robot of that type. That means if you encounter all robot types in a stage and answer at least one question for each of them, you get an extra 9,000 points in bonuses.
