Elyments is a very intriguing and fun game on mobile devices. It's free to download, and after downloading it, you can use the Elyments straight from your Google Play Store or App Store. I've found that the free trial version works the best, as it allows you to try out the Elyments first-hand before buying it. However, if you want to actually purchase the full version, that's fine too, but I would suggest going through Google Play first to make sure it's available and then go straight to the application page on their Android app. It really is a simple app, and it's worth checking out.
You can get the free version, but it has some limitations. For example, you can only add five items at any given time. The other five can't be added until you save and enter them again. It also doesn't let you edit the information on the cards at all, nor does it let you select any of the colors to use in the game. However, these are minor things. If you want to spend some money on the full version, it's a small amount to download the free version and then buy the full version after getting some use out of it.
There are a few problems with Elyments, too. First, it takes forever to load up, so you might not get a chance to try it out before purchasing the full version. Also, after buying the full version you can't transfer that saving over to another phone, so you need to spend money again on new Elyments if you want to try out this feature. On the bright side, though, I've found that the free version works great for me on my iPhone and LG phones. I'm sure there are plenty of positive reviews out there for this interesting download.
