Arcane Legends makes it easy to earn hundreds of platinum for no cost. This guide is for Android and iPhone users as I have not yet seen the offers they provide for the PC. First, you want to start off by logging in on your device and opening up the menu; from there, you want to select the platinum in the bottom left corner with the '+' sign next to it. I've provided a picture below:
After you click on that it will prompt you to purchase, but when you click the 'x' button on the purchase page it will ask you if you would like to earn free platinum. It will look like this:
Select one of the first two. You can earn gold easily in-game so you shouldn't waste your time completing offers for it. Besides, a lot of the things you can buy with platinum you can sell for a lot more gold than you would get completing offers. Anyway, if you select the first option you will come to this page on your device:
When you get to this page you will see a ton of free offers but my advice is to complete all of the offers that ask you to "Install and Run" because after you install it and run it you can uninstall it immediately after if the application isn't to your liking. Even though most of the downloads will only give you 4 platinum, there are so many offers for them so the platinum will add up fast. Within one day I had 250 platinum purely from installing and running all of the games it asked for and more games are added to the list almost every day. Feel free to complete the surveys but they are a little more time consuming.
If you have any other suggestions or questions, feel free to comment below.
