Different games contribute different percentages, and Mr Play has a few games which contribute 0%, one which contributes 10%, and quite a lot of games which contribute 50%. Anything not listed will contribute 100%. I can't send you the link because it's not really a link just a pop up on their website when you check the Bonus Policy but if you click Bonus Policy in the second column of the footer, then scroll down to section 3: Promotional Play Restrictions you'll see at the end of the second paragraph 'wagering requirements' is hyperlinked. Click it and it will take you to the list 🙂
