For this project, our team designed a carnival-style game of skill intended for adult players. The attraction combines elements of Skee-Ball and pinball: players launch balls using a spring mechanism and attempt to land them in tiered targets on a rotating carousel. Points are awarded based on accuracy and difficulty, and high scores unlock prizes. The design emphasizes safety, repeatability, and fun, while operating entirely on battery power with no external computer required.

Goals

Create an interactive and engaging game of skill for adult fair-goers.
Combine the launch mechanics of pinball with the tiered scoring of skee-ball.
Ensure the system is safe, self-contained, and battery-powered.
Encourage replayability by displaying live scoring and high scores.
Incorporate an attractive aesthetic to enhance visual appeal.

Features

Spring-based launch mechanism that lets players control power and angle of shots.
Rotating 3D-printed target carousel designed in Fusion 360 with multiple tiers and varying hole sizes for different point values.
Automatic ball return system using angled surfaces and PVC tubing.
Electronics powered by Arduino, including a DC motor, ultrasonic sensor, and 7-segment score display to record player score.
Safety features, including the use of Nerf Rival balls, spring force limits, and enclosed netting.
