Here is a link to a Kahoot game that I used in my class on zero conditional and first conditional: Zero and First conditional by marialakhuti

It worked fairly well in my class, although the last question, number 10, confused my students slightly.  The answer was: If public transport is good, people stop using cars.

My students thought it was "will stop using cars."

I explained to my students that it's a zero conditional if you are talking about world-wide trends.  It's a first conditional if you are talking about a specific future in a specific city.
