A: When you have completed the N-th mission in T seconds, your average speed SPM is updated using the following formula:
SPM[1] = TQ: Can I send you an email to report a bug?
SPM[N] = round(SPM[N-1]*(1-K)+min(T, SPM[N-1]*1.2)*K)
where K = pow(0.7, N)+0.3.

How to play the Broadcast game
The objective of the Broadcast game is to connect all of the terminals and cables on the grid to the central hub by fixing their orientations. All you need to do is click and rotate the cables, the terminals, or the hub.
Be aware that the edge of the grid wraps to the opposite side as you can see from the illustration above.
