Koltera

Koltera is a creature-collecting idler where you mine and train creatures to improve their strength and the output of your operation. As you grow your operation, you can discover new creatures and trade with traders.

Collect and improve creatures

Koltera has 41 unique creatures, each with 11 augmented versions, for over 450 creatures to collect. Each creature has its own genetics and species base stats. You can balance different creatures, breed them to improve their output and try to create a perfect one.

Grow your operation

Your idle mining operation accumulates coins, and you can increase its output through upgrades and other mechanics. More than 18 different effects can be upgraded. You also earn uncapped offline progress: while you are away, your operation accumulates coins and lumin.

Trade and summon

You can trade with traders to discover new species; rarer creatures have increasingly harder requirements. The garden plays like a typical incremental game and lets you summon legendaries.
