It's Titan RNG, a simple but fun game to play on roblox.
Every few second you summon and entity and have various posibility of what you can get.
From the least rare probabilites of 1/2 to the moste rare of 1/800'000'000 there is a bunch of em.
My rarest is 134'000'000 and i got it after 134'000 summon.
There are various mechanics in this fun game like the base,
Allowing you to upgrade your base and your stats.
Really nice way to spend my time. There is a lot more to explore in that game like enchantement that give more stats to your summons, weather that affect luck, the way summons get there value based on a lot of factors, or even the items you can find to increase you stats but it mighty become too detailed and incomprensible.
Definitely a good game.
