Counter to preset number for different output

[AnteBante]

I am building a very simple thing for a show where
I want every 29th push of a button to be one output
"NO WIN / RED LIGHT" but every 30th push should
be another output "WIN - SOUND - BLUE LIGHT".

As I normally do my stuff in 12V it would be perfect
if anyone could tell me where to start looking for the
counter that I can program to send out the current
one way on every x (30th in my example) current (push on
the pushbutton).

All helpful hints would be very appreciated.

I'd suggest using two simultaneously-clocked 5-or-more-bit counters: one which resets at 29 and the other at 30.
You could use standard CMOS 7-bit or 14-bit binary counters. Logic gates would be needed to detect those counts to cause reset, and (presumably) to prevent both lights coming on at multiples of 29*30.
I don't see how you can do this with a single modulo-30 counter, as that would result in the lights being actuated at counts 29,30,59,60,89,90.... rather than (as you require) counts 29,30,58,60,87,90....
