English phrase into Latin

Could someone help me translate the following phrase into latin please:

"Level Playing Field"
as in the case of equal opportunity.

I tried various dictionaries and got some answers, but I am worried that these might just be automatic (machine) translations which could very well be meaningless.

Here is an example: "Campester Lascivio Agri"

I also searched for the words separately and got:
Level: aequus, planus, par
Field: Ager, Avrum

no matches for playing as opposed to play.

Someone out there please help

Many thanks
