Christmas update crashes


Just downloaded the new Christmas. Played 4 or 5 portals and it crashed after each game. Lost some of the items I'd won. Now it just continually crashes. Can't even get a portal to open before it goes down.
Used up all the free energy given for my patience waiting while the new content loaded playing the game to no avail. The items won playing the Christmas portal don't stick around. Have won the same golden candle 4 times. Can never get more than 3 stars so can't open up any presents. The game crashes and everything gained disappears. Major bugs in this update that need to be fixed.
Even though a fix to the crashing problem was released, it did' help. I can play a portal, but the game crashes again immediately, and while it uses up my energy, i don't get credited with any of the items I won. Consequently, I have been stuck with only 3 bells and 1 star for over a week. I do get credit for the item I'm awarded for playing the game daily, but that's about it. Hoping the game will work again once the Christmas special is over because they sure can't seem to fix it. Now it's too late to have time to win any of the Christmas special prizes.

Twin moons


Oh where to start, this is the second time I have elected to play this game and once again I am disappointed in so many ways. First the positive your graphics are among the finest and that is about it. Now saying your graphics are beautiful does not mean that hiding the hidden objects by making them shadows of the real object is not playing fair, not having all the objects out at the beginning of the round is also not fair, and having several objects named the same thing is also not right. It should not be necessary to hook to social media to get friends in the game or to complete collections. I also do not like games that have nothing to do with hidden object such as the connect three, or the string untwisting that have to be played to proceed in the game, if I wanted to play these games there are plenty of them out there. Also it cost to much to play this game as you get to the higher levels.

Needs work


This game could be fun but there’s too many frustrating issues. First it takes forever to load items or open scenes. Oh my goodness I feel like this could absolutely be the death of this game. Other G5 games load much quicker. Second, while I enjoy a challenge, a lot of the items are WAY too hard to find! I have used hints to discover an item was completely concealed behind something. How the heck am I supposed to find that on my own? Third, the obscure items needed to complete the collections are ridiculously hard to come by. If I need 10 bronze medals to finish a collection then it shouldn’t take me 300 tries on the same (now boring) board to get them! Lastly, once you get to a certain level the portals become crazy expensive to open. 100,000 coins?? Give me a break I can barely earn 50 on each board!!
I feel like I have given this game plenty of opportunity to grow on me, even spent a little money on it, but I’m about to delete. It’s just not fun.
