The 9 box lottery is permanent, I think. I doubt the gems daily (more like every other day) is permanent. Have yet to see any good prize from 9box, the best I have seen is probably 1000 honor points, and I only got green grass. lol
There will probably be a Gem on Rarity 9. Even then, though, it won't affect their revenue too much because after getting something from Rarity 9, you will be bumped down to Rarity 8, meaning out of four days, only 1 day you can get a gem, or 1/4. Also, there will probably only 1 gem out of those nine tiles, meaning 1/9 chance. From those four days, the chance of you getting 1 gem is 1/36? Hahaha… Getting 1 in 36 six days should already be considered lucky.
I love this feature though. It keeps player interested to log in everyday. Wondering what Rarity 8 and 9 will offer since those are basically what we, daily players, will get.
