Hello “One in a Trillion” I love your game❤️📱! But I have a few ideas for your game. First maybe add rare special versions of eggs named ✨glistening✨ eggs that can spawn, they’re basically like shinies from Pokemon, I feel like this could be really satisfying if you got one! Second, daily quests! These will add something more rewarding to playing every day! Third, Bounties! Bounties will happen every week or day, if you find the bounty egg you will get rewards… it will randomly pick an egg for you to get based on how far you are in the game. Thanks for reading 📖! And thanks for making this game!

There is a limit on everything you can collect

Gems and minigame eggs, which are super important for making progress, are bottleneck/timegated. You can only get so many a day and then you are cut off the rest of the day. You basically can’t do squat without gems because you need them for just about everything. If you are cut off then you might as well stop playing because you will never get anything done. At least with the minigame eggs you can add more stuff to them but there’s still a strict limit which stops you from enjoying the game once you hit it. I hate how almost every mobile game these days tries to dictate how much players are allowed to play the game, but will gladly let you pay to get more resources bypassing what you’d normally be able to get without paying. I’m not even kidding when I say this game would be one of the best mobile games ever made in human history if it wasn’t for that, if the limits were removed my review would instantly shoot up to 10 stars and I would start playing the game again. I just want to go back to the good old days when the developer wasn’t loony and the game was fun

loving it

used to play this game a while ago, lost the data, made a new account in 2024, stopped playing and now ive come back in 2026, this game is so fun and the base game is extremely simple once you understand it. either my memorys terrible, or i remember that there used to be upgrades or something, but maybe im just remembering wrong. this is a great game though, and i hope it reaches more people

Great updates!

I played this game a while ago, 1 or 2 years to be exact,and a lot has changed since then.unlike many other greedy games,only pushing out updates like a factory to boost revenue, one in a trillion’s updates have only improved and evolved the experience! I am sure that if I do stop playing and come back in a years time, it will only get better! 🤩❤️

It’s good

Best game needs more updates! (EDIT)

I love the game but I have 2 problems: first is No good tutorial like maybe you could have some egg professor teach you everything and then give a good egg after the tutorial! Next more updates it just seems there’s nothing new? Is there more eggs? Idk? Anyway I would love for you to make a potato egg with sunglasses! It doesn’t have to be differently shaped or anything just brown and sunglasses I don’t even care if it’s a 1 in a 100! Anyway I love the game and will continue to support it! Edit: hey guys can you plz at least update me on if ur gonna add it, it’s fine if you don’t I just want to know! 😁👌

Everything I ever wanted in an app and more!!! The review is sorta long lol

WOW!I just have to say—I absolutely LOVE this game! It’s one of those rare gems that immediately pulled me in and just refuses to let go, in the best way possible. The developer is clearly someone who truly cares about the community and the players. You can feel it in every little detail, from how smooth the gameplay is, to the fact that there are no annoying ads interrupting your fun. It’s so refreshing to just enjoy a mobile game without feeling like someone is constantly trying to sell you something or break up the experience.

The gameplay itself is just so addictive and yet so wholesome at the same time. I find myself smiling constantly whenever I open the app, and I can’t get over how fun the multiplayer mode is! Playing with friends—or even just random players—feels like a big part of the charm. It’s the kind of game that you can pick up for a few minutes and suddenly realize an hour has gone by because you were having so much fun.

I do have a couple of little wishes that would make the game even more perfect if they ever get added. First, I’d love to see egg descriptions! I find myself so curious about the little details, and I think it would be such a fun way to add even more personality and depth to the game. Also, it would be amazing if you could spend gems to change your username—sometimes you just want to refresh your profile or come up with something silly to match your mood!

But honestly, even without those things, this is hands-down one of the best mobile games I’ve played. And that’s saying a lot because I actually have Apple Arcade, and this game still stands out above the rest. It’s charming, fun, super addictive, and just such a happy experience from start to finish. Huge kudos to the developer for making something this special—I can’t wait to see how the game keeps growing and improving over time!

EDIT:
The dev actually responded! This is customer service Nintendo.

Game sucks

I was a top 3 player in rated league and played hours a day. I was then banned from the discord over some stupid mods power tripping about dumb things. The leadership and community are unbelievably toxic and ruin a great game idea and mechanic. This game is great except for the terrible terrible moderation team. Especially MommaOfRascals, what a weak loser

Sound Disabled?

Great game, love the grind. But, where did the sound go? Is it just me? And can’t find any audio settings, so it’s either a bug on my end or it’s widespread.

Really fun!

The game is very well made and is a very good idea! I would recommend adding a percentage increase for the player with the better accuracy in 1v1 battles and Mabey a gallery for the all time luckiest mini games played so players have some more stuff to aim for and making a really lucky mini games played more satisfying. Apart from that it’s really fun and the only thing that would make it much better would be events like Christmas and Halloween.

cool game

i really like this game and have been playing for a while but honestly i liked the old system better, with selling eggs and using money to enhance minigames, now with this new yolk system and trading in yolks to make minigames better is kinda confusing, also the money i had previously went away, and my rare eggs dont really matter now as i have to grind these new minigames back to the old point

Wow!

This game is a hidden gem There is soooo much to do. 1000% recommend

It’s eggs

It’s eggs

PLEASE LOOK AT THIS DEVS!!!!!

Ever since you removed money about a year ago it has been nearly impossible to progress at all, I had billions and it was removed with no compensation and I ended up quitting the game, please fix it by adding money back

The old days

As good as the game is now, I remember it being more fun and easier to actually progress in when we had the money feature and when you could sell the eggs to buy lucky sauce etc. I would love it if that made its way back into the game. I have found the nowadays it is so much harder to get any rarer cards from mini games and I have a lot of rare eggs, but only from when the money feature was in the game, now I just can’t seem to get anywhere close to them. I would love to see the money feature in an upcoming update please, otherwise amazing game!!

:)

I play this game in 3 day spurts once in a while, every time I start playing again I wonder why I stopped. Sometimes it’s hard to play this game while I have school, but I think now’s the time that I grind again. I wish I could give a trillion reviews, but I haven’t unlocked that egg yet. Expect me on the leaderboards soon 😉 (1t/10)
