Easy

Light one racer. Send to upper playfield. DO NOT COLLECT racer, instead bonzai run. This increases in value and maintains over balls. This gets pretty large 250K? cap.

Medium

Same as Easy, but after the reward gets to 100K start spelling ABC in upper playfield. This doubles the bonus.

Alternatively – Anytime ball enters left flipper, combo onto right ramp. This gives a lap. Laps are worth bonus points every ball. If you stack laps, bonus can get quite large.

Hard
