About this game

Generate and collect thousands of cards. Hunt the ultra-rares almost no one will ever own.

Every card rolls two independent rarities, so there are 1,000 normal cards and 1,000 holographic Shinies to chase, 2,000 in all. The rarest are rarer than 1 in a million to pull. And every card has a 1 in 50 shot at being Shiny.

GENERATE & DISCOVER
Create new cards on a timer, then watch each one reveal. The rarity climbs as the card comes into focus, and the rarer it lands, the bigger the moment.

HUNT SHINIES
Every Shiny is holographic and 50 times rarer than its normal version. Completing the Shiny set is the ultimate flex.

BID, DEAL & SELL
Outbid real players in live auctions to snag the cards you're missing, grab limited daily deals, and sell your spare eggs back to the game for coins.

JOIN A CLUB
Team up with other collectors, pool your finds, and win weekly club bounties together.

NO ADS

I play One in a trillion currently so when I heard that the same dev is cooking up another game, I had to try. And oh my gosh did he cook! I love collecting cards in general so this game does a great job at scratching my itch. I do wish battles had a better payout and at the moment, I don't see much of a reason to do it. But I am still new, and the game is new too. So I won't hold it against anyone. Overall, great game! Love playing it. Keep it up!

I use to Plat OiaT, this is definitely better. I like that you can't play endlessly til you get bored because you gotta wait to roll for more cards. I like the concept of collecting and the shop where you can bid and but cards to add to your collection. You can also fight other eggs with your own and get some pretty good rewards! Overall, an amazing game and I am already hooked.

Another gem from this dev. Shellkeep is a fun, casual game where you gradually build up a collection of cards of varying rarities to try to eventually get them all. One of the coolest features is Clubs, where you can be in one with your friends and family and work together to complete your Club collection and get weekly rewards for being active. A very polished game, and a perfect game to play alongside the dev's first game, One in a Trillion. No ads either! I highly recommend both games!
