Great free to play game
I usually open up and play this app several times a day. It’s the sort of game that uses energy to play. Although you also can plant and sell crops and goods. (They cost game money, but not gems nor energy)
On days that I’m too busy, I don’t have to worry about collecting items. The goods do not go bad or expire.
The longer you play, the more energy you can store. Plus there are opportunities to earn trophies for events that give you extra energy.
Game play could be frustrating until you understand the options on where to spend your energy. There is a main story line, the trial race story line, several events, plus a home location. You also have to know what resources you need to have on hand to produce goods that are needed often. For example fire. My advice is to not worry about the trial race or events until you figure out the game play. Realize that you will most likely have to play this game often for short periods of time. I have ADHD, so this works out great for me. Lots of options, so I don’t get bored repeating tasks. And I can spend 5 minutes and be done until I remember to open my app again.
I have never purchased gems to play. There are videos to watch if you want extra energy or rewards. However you can always skip adds.
