The first and most important distinction to make is the difference between "PC Exclusive" as a marketing term versus a platform reality.
No official publisher (Wicked Witch Software / Tru Blu Entertainment) has ever released as a free-to-play title. There have been occasional discounts on Steam or the Humble Store, reducing the price to as low as $9.99, but never a permanent free exclusive. If you see a website claiming an official "Rugby Challenge 4 free download PC exclusive" directly from the developer, it is almost certainly fake. rugby challenge 4 free download pc exclusive
