I've been playing around with the Ziliqa Planet App on my phone for the past few days. It's raw but pretty fun. The Super Player game takes me right back to the old dungeon exploration games I used to love on my first computer - a Commodore 64!
You can collect Zil from the planet and there are other apps which will be coming later. I liked it enough that it was worth it for me to play with it a bit by investing a couple thousand Zil in the pool. This allows me to collect 10% extra rewards.
I recommend you give it a try but (like me) don't throw a bunch of money at it - just a little to start - let's see where this goes. . It's a cool use case for Ziliqa. As you can see - if you use my code, we both are supposed to get some benefit from it. My code is 5NRQ
