This work presents a new verifiable and coercion-free voting scheme Bingo Voting, which is based on a trusted random number generator. As a motivation for the new scheme two coercion/vote buying attacks on voting schemes are presented which show that it can be dangerous to let the voter contribute randomness to the voting scheme.

A proof-of-concept implementation of the scheme shows the practicality of the scheme: all costly computations can be moved to a non time critical pre-voting phase.
