About This Game

Tired of unimaginative grindfests with no gameplay behind them? Here's something you can actually sink your teeth into.

Card Girls: Shimmerdeck is an adult card-collecting, engine-building game about figuring out how to squeeze absurd amounts of Stars out of a deceptively simple board.

Build around the synergies you discover, hunt for wild combinations, upgrade your favorite girls, and turn a few innocent-looking cards into a completely unreasonable Star engine.

Build Your Star Engine

Simply filling every slot won’t get you far.

Each girl has her own stats and a unique ability. Some empower neighboring cards. Some want to sit in very specific positions. Some scale off the cards around them. Others can reshape your entire setup.

Experiment with placement, stack effects together, and discover combinations that make your Star production skyrocket.

Crack Open Boosters

Spend your hard-earned Stars on booster packs and see what you pull. Grow your collection and hunt for the cards your current strategy needs.

Pulled a duplicate? Good. Extra cards are fuel for making your favorites stronger.

Shred. Upgrade. Repeat.

Shred unwanted cards into Shards, then spend them to upgrade the girls you want to keep.

Upgrades improve stats, strengthen abilities, and unlock new gallery artwork. A card that seems ordinary at first might become the centerpiece of your next big strategy.

Fill Out the Gallery

Every girl has her own collection of lewd artwork that gets progressively more explicit as you upgrade her.

Choose your favorite unlocked images to display on your cards and board. Whether you prefer the earlier artwork or the more revealing upgrades, you decide how your collection looks.

But seeing everything takes more than just opening enough boosters. You'll need to invest in your cards and figure out how to make them work together to unlock everything they have to show you.

Take a Break From the Board

Want to change things up? The main engine-building loop isn’t the only way.

Tackle special Challenges, solve jigsaw puzzles, or test your luck in Shardle. Each offers a different way to play and earn extra rewards.
