One in a Trillion is a casual collection game you can play for years. Even if the insanely rare eggs seem hard to collect, you can work on creating Glyphcards and compete against friends in daily leagues for prizes.

Experience our unique dragging mechanism in the core gameplay, which is more satisfying than traditional clicking or tapping.

Multiplayer seamlessly blends effort and luck for a casual take on competitive play.

While this game is not idle, fans of incremental or idle games may find enjoyment here too.

I haven't played in about a year, but decided to play again recently. Im sorry to say that the game is not fun anymore. I used to love it and would play it for hours on end, but after the new update it has become boring. I loved having in game money that I could spend to get luck sauce. The fact that they changed it to gems annoys me, especially because all that money I saved up went to waste. It feels so lifeless now and I don't get that rewarding feeling when I find a new egg anymore.

I could write a trillion words (almost) about how great this game is. if you love numbers than for sure you need to try it out. The 1-person development team has put in the time to fine tune things and it shows. The game is perfectly balanced, not too easy, not too hard, and no way to exploit any aspect of the game because he spent the time to ensure that the choices you have to make are always "fair trade" more or less. Also no advertisements is a huge plus. community on discord is A+

EDIT okay, I'm glad there is a fix, but gameplay on all my other mobile games is not sped up in any way because i have this option enabled (it is enabled for a reason). this is a first. surely there is a way that can be patched in the next update? i shouldn't have to change the graphics/animation functionality of my entire OS interface just to use the game. (granting permissions that are required is something i expect, obv, this is not)
