Lots of fun!

You can play this game without spending money. You might not make every challenge and might not win every prize, but you do not have to.
Not making a challenge does not ground you.
I have had loads of fun already and still a lot ahead of me.
Enough new tasks show up to keep it interesting but not too many, do it does not get frustrating
