How I love this game

Love the game platform. Lots of fun slots too. I could play this all day long if I didn’t have to work. I delete most games I play but this is one that I really liked from the start. How many words do we have to use to explain TJ great game we are playing. I can feel my face when I’m with you as one of my favorite songs. Maybe you guys can make sure to play that behind one of the slots or maybe even create a game called I can’t feel my face when I’m with you. That would be a blast. I really would love to see a game like that if it was out there. That’s something I would probably play all day long. Of all the games I’ve ever played online, this has to be one of the best. There just are not enough words in a vocabulary to discuss how great this game is. I surely wish that I could give a lengthy review to explain to everyone just have fun and cool this game is.

Bonus rounds

I am not sure what you call the 20 minutes competitions but I don’t understand why if you get a bonus round such as the cherry lock or free spins, whatever you win doesn’t count towards the coins won for the competition. It is supposed to be based on your winnings from the spins during the 20 minutes and those coins are winnings, so why don’t they go towards your total? You lose the time it takes to spin for cherries or use your free spins and then don’t even get credit in the competition for your coins won, which then makes it nearly impossible to rank in the top 50 let alone the top 10 which is one of the daily challenges. I usually make in app purchases and I love the slots you offer but I won’t be making anymore purchases in an app that has basically forced me to make daily purchases to meet the daily challenge. It’s a shame because I truly enjoy this app and have spent money here in the short time I have had the app, but there are so many other apps to choose from that I don’t see the point of spending my money on one that has such strange competition rules or guidelines. I win the coins during a competition that is based on spins and winnings but they don’t count??? Does not make any sense. I will play without purchases for another week to see if there are changes made but if not I will probably be taking my credit card and my time to another app and another app company. Sorry

The Money Tree Game

With the free credits I received upon downloading this app, I was able to play for a solid hour and a half without making a purchase! With great bonus features I had gotten up as high as $174,000,000!! Unlike many other iPad slots, the “stop spin” button actually stops the spin without any delay. I am big on spin stopping, which is how I was able to win as much as I did. Warning: this game is highly addictive!
My only negative criticism would be that it seems like the size of your bet is inversely proportionate to how many times you win. But I suppose that contributes to its similarity to the real thing. Happy spinning!! I will be uninstalling several of my other slot apps because this one makes them seem boring
