CALL
A Caller takes a position on an outcome.

One individual CALLS-IT. Another individual accepts the CHALLENGE. Friends and followers become BACKERS and choose a side. The official outcome decides the winning side.

CALL-IT is built around the pari-mutuel principle: members create the sides, the crowd builds the pool, and the official outcome determines the winning side. No house line. No house side.
A Caller takes a position on an outcome.
A Challenger takes the opposing position.
Followers and friends join either side.
The winning side shares the collective pool.

Make the CALL. Build your crowd. Let the outcome speak.
