About a month ago I started playing the Pokerstars Challenges (eg. "Jacks or Better;" "Poker Challenge"). I am speaking specifically about any challenge that promises a cash reward (daily challenges are typically easier to complete, but only payout a ticket to a scheduled tournament, with hundreds of tables, and limited payout). These challenges promise a payout between $1 and $10, 000, but I have completed dozens of them and can confidently say they pay one dollar more often than not. I've received $2 and $5 dollars before, but these too hardly seem worth it for the work you have to go through to complete the challenge. And you don't know how much you're playing for until you have completed the challenge. Their Spin&Go games seem much more fairly paid, and you know what the pot is before you play the first hand. I think far fewer people would play the Snin&Gos if the pot were similar to the challenges. Until this disparity is addressed, I will not be playing any challenges and I will encourage others to avoid them.
