About This Game

IIdle Alien Fishing is an idle fishing game that runs along the edge of your desktop, automatically catching fish and keeping your restaurant and aquarium going while you focus on other things.

Do your thing

Work, study, or scroll through videos while the game quietly runs beside you. Drag it wherever you like, or hide the sky and scenery layers entirely. Pack away the whole sea and leave just a little boat on your desktop—or give your restaurant a corner of its own. Let it keep you company while you take a break.

6 alien seas, over 700 variants to collect

Explore 6 individually designed alien seas, each with its own scenery. Discover 240 species of alien sea life, with over 700 rare variants to collect. Unlock shimmering foil cards for your in-game field guide!

Upgrade your rods, fish storage, sonar, and thrusters to gradually unlock new waters. Look out for creatures you haven't seen before, and keep an eye out for new forms of familiar species.

Run a space restaurant

Turn your alien catches into 150 dishes, with just about every kind of meal you can think of. Choose recipes, prepare dishes, and set the menu while your staff serves the customers. Upgrade your dishes and customize your restaurant with 9 categories of decorations. Take your time building a more inviting place to eat.

Guests arrive from all over the universe, with different appearances, species, and home planets. Save your favorite guests so you can invite them back for another meal. As your restaurant becomes better known, you can even send your food to every corner of the cosmos—by rocket!

Keep your restaurant stocked with a steady supply of ingredients from the fish farm. And how do those deliveries arrive? They come by rocket too!

Open fry pack blind boxes, customize your aquarium

Buy packs of young fish, add them to your aquarium, and let them grow—or feed them to speed things up. Check back later to see how they've turned out and what surprises are waiting. They'll also earn a steady income to help you keep expanding your aquarium. Or do nothing at all and just watch the alien creatures you've caught swim around for a while.

Keep your rare finds together, give them names, and choose decorations to arrange your aquarium just the way you like it.
