Like acquiring bloodlines, there are two ways to get RELL Coins. The first way is through codes. I'll say it again, RELL Games hand out codes like they are candy. Check their Twitter and YouTube. They will almost certainly have a code you have not redeemed yet. If you are reading this soon enough, they have a challenge that for every like their tweet gets, they will drop a code that equals two RELL Coins. They do these challenges from time to time, so be sure to check Twitter regularly. The second, more expensive way is through Robux. I cannot recommend this method, as I am a big fan of F2P (Free to Play), but if you want to, just head to the shop and purchase RELL Coins with Robux. Do remember that they are expensive and not generally worth it.
