For Pennywire, the lower rotary control will tilt the linked rails continuously. Gravity, rolling resistance and momentum at each transfer determine whether the 10-sats coin reaches the target or falls from the course.

Erato was reported at the Leipzig Autumn Fair in 1910 and appears to be the direct predecessor of the later Jemoc. Jentzsch & Meerz had filed a utility model for a skill coin machine with swinging tracks on 9 December 1909. Historical reference: Alte Spielautomaten.
