About this game

Idle Blob Colony is an idle creature collecting and breeding game where you raise adorable blobs, discover rare colours, build machines and grow a tiny tank into a thriving blob colony!

Start with two basic blue blobs and breed your way through new generations, higher tiers and rare colours. Automate your colony with machines, care for your blobs, research hybrids, mine valuable resources and battle hostile creatures as your collection grows.

BREED, COLLECT AND DISCOVER NEW BLOBS

Breed blobs of the same colour to create new generations and work towards rarer colours and higher tiers.

Every discovery is added to your Blob Journal. Undiscovered blobs remain hidden, so you never know what strange little creature is waiting to be found next...

Can you discover them all?

CARE FOR YOUR BLOB COLONY

Blobs are cute, loyal and occasionally disgusting.

You will need to:

• Keep your blobs fed
• Clean waste from their tanks
• Treat sick blobs with medicine
• Transfer blobs between tanks
• Sell spare blobs for Energy
• Protect valuable blobs during fights

Ignore their needs for too long and they may become ill. Send an unprepared blob into battle and it could be lost permanently!

BUILD USEFUL MACHINES

Expand each tank with machines that help your colony grow:

• Breed Machine – breed new blobs
• Food Machine – automatically dispense food
• Poop Machine – clean waste and turn it into Energy
• Turret Machine – assist during fights
• Mine Machine – collect valuable resources
• Breed Lab – research completely new hybrid blobs

RESEARCH HYBRID BLOBS

Build the Breed Lab and research what happens when two different blob colours are combined.

Choose how much Energy and minerals to invest, wait for the research to finish and hope the experiment succeeds. Greater funding improves your chances, but success is never guaranteed!

Successful research unlocks unique hybrid blobs.

MINE ROCKS AND COLLECT MINERALS

Rocks periodically appear inside your tanks. Equip a pickaxe and mine them manually, or build a Mine Machine and hire a blob to do the hard work for you.

Collect Iron, Sapphire, Ruby and rare Zeptarian. Use minerals to purchase advanced machines, fund research and trade with unusual visitors.

MEET THE MYSTERIOUS TRADER

A mysterious travelling blob may occasionally appear inside one of your tanks.

The trader offers minerals, unusual items and mysterious eggs. Decide carefully before the opportunity disappears!

ENTER FIGHT MODE

Think your blobs are strong enough?

Send them into Fight Mode and face increasingly difficult waves of hostile creatures. Improve their health, attack and defence, build a Turret Machine and earn Energy by surviving each wave.

Be careful: defeat has real consequences, and blobs can permanently die in battle.

COMPLETE REQUESTS AND MILESTONES

Earn rewards by breeding and selling blobs, discovering new types, mining rocks, completing fight waves, buying machines and transferring blobs between tanks.

BUILD YOUR BLOB EMPIRE

Expand from one small tank into a collection of busy blob habitats. Discover rare breeds, automate everyday tasks, improve your equipment and keep pushing towards the most valuable blobs in the game.

Idle Blob Colony includes:

• Idle blob breeding and creature collection
• Multiple colours and progression tiers
• Virtual pet care, colony management and tank building
• Rare hybrid blob research
• Idle-style machines and automation
• Mining, minerals and equipment upgrades
• Strategic wave-based battles
• Goals, milestones and collection progress
• English and Japanese language support

Forget dogs and cats.

Blobs are clearly the superior pet.
