All three games are from the same devolopers, and that's it:

They're all pretty similar, too, and you might think of it as a single game that just isn't linked yet. But they're supposed to be. With an exchange where you can convert the resources minted in the game into one or more tokens. These should then also be tradable on other exchanges.
The games themselves have actually pyramid character at first sight like all other Tron games by the way also. But you also compete with other players. And not only, as with other games, for the earliest entry, but also in tactics and decisions. So if you're good and do your math, you can still be successful with a later entry point. I tried this myself with a second account.
Tronsilver is the inexpensive variant and you can get started with 5600TRX and have already reached a good level after four days. With the other two you need 18000TRX to play properly.
If someone uses my refs, he can also expect help from me to expand them to avoid the typical beginner mistakes, which unfortunately cost money here.
