A program that grants points for using Bing search, which users can redeem for gift cards, sweepstakes entries, or charitable donations.
You don't actually need to complete the puzzle to get the point, you can right click+open in new tab and it'll give you the point. Still, a fraction of a cent, but they needed to decrease the points, no doubt. I did some quick calculations and if every user of bing was a rewards member, using it to the fullest, they would have given out up to about $1.2-2.4 trillion over the length of their program That's 7-15 years of their total REVENUE. they needed to drop the point amount and I'm sure will continue to do so, or else it would get way too expensive to be worth it as a business move. They are paying you for R&D+ acquisition of you as a customer, reducing revenues and advertisement given to GOOG
I know it sucks though. I really wish I knew of the program back in the day, I would have given bing+edge more use.
