This two games have one thing in common, the randomly falling wild symbols and the only different is that when a wild symbol appeared on a reel, you get a re-spin (Gem Drop).
First time playing this game was on my mobile because I received a text from Casinoeuro regarding free spins no deposit needed.
So I started the game on my mobile and they've added my account with 1 euro, it's equal as 20 free spins on Gem Drop with the lowest bet. I wished that this game had more paylines because it would be one of the best payed game ever.
Believe it or not but I have played this game for half an hour with only the euro I got from them, also I got a few bonus rounds with it and unfortunately no big jackpot won thou but I manage to get the second wheel spinning :)
Never got any big win playing this game even when I doubled my bet for a while but I did see the tasty jackpot won several times during my play time so I do believe that it's possible to win big.
The game is good and the jackpot are very attractive but after a while you'll get bored because the game is just too simple and simple games don't last long.
I hope in the future PlayNgo will bring a sequel of this game but with more paylines and if the time comes I would be the first playing it (hopefully).
I do recommend this game to all my fellow gamblers or slot fans because of the game feature (falling wild symbols) and of course because of the jackpots. Till now I still didn't get any jackpot, not even the smallest.
I wish you all good luck and hit that jackpot and share it (just kidding).
