Target Points

Challenge: In this game, the VR Robot starts each drive at the red Start Position in the center of the board with a starting score of 1000 points. The object of the game is to drive the robot to draw lines that hit the targets on the game board to score more points. Each time the robot arrives at a target, the starting score is updated based on the arithmetic operation along the pathway(please see the Game Board image). The robot also receives a bonus score based on its position on the target. The closer to the center of the target, the more points the robot gets! The highest score wins!

Bonus scores are as follows:

The robot arrives at the Outer ring: 200 points

The robot arrives at the Middle ring: 5000 points

The robot arrives at the Inner ring:10000 points
