Have thoroughly enjoyed this site, but lately it freezes. I have been unable to finish the picture on my tablet or phone. ***12/6/21 update. Freezing episodes have been resolved. I've played other color sites, but this is, by far, the best. Limited commercials make it especially nice. There is a variety of subjects. I always do the daily choice (I call it my homework.) Have moved its rating from 1 to 5.
