Are the swag bucks “deposit money into this game get an abused amount of swag bucks” legit?

I’m new to all this and I started on swag bucks. On the website they had a thing to deposit $10 into a solitaire game and play 3 games and you’d earn 5k Swagbucks which comes out to be like $50 visa gift card worth. Is this legit? I already did it but I’m afraid to do more until the holding time expires and I get to cash out.
