In the past, there were different options for rewarded ads, including more ads for coins. As we’ve started to add new options for rewards, such as hints and more, some of the old options were changed. 

While not intended, some players still saw the old options rather than the updated ones as time went on. This has been adjusted so all players should now be seeing the same type of rewarded ads. Since we’ve been adding some exciting new types of rewards, we want everyone to have access to them.
