Roly Poly Lab : Isopod Idle

Raise a colony of roly-polies, breed them for rare looks, and work out which hidden genes each one carries.

A LIVING TERRARIUM
Hundreds of isopods wander the leaf litter, curl up when you tap them, molt and gather in swarms. Feed the colony to earn Compost, upgrade it, and watch the crowd change as new traits spread. Every look on screen is inherited — colors, spots, stripes, mottling and rims all come from genes.

BREED AND REVEAL
Pick two parents in the Breeding Lab and four kids hatch about 90 seconds later. Reveal them one by one or all at once, keep the finds, and send the rest back to the colony so their traits spread.

FIND THE HIDDEN GENES
A plain-looking isopod can carry a rare recessive gene. Follow the odds on each card, test-breed to confirm who carries what, and catch the glowing mutants that bring brand-new genes into your lab.

FILL THE FIELD GUIDE
49 morphs across three habitats and three body types, inspired by real hobby isopods. Every morph you catalogue makes your colony grow faster, and Discovery Notes and Collector Orders give you more to chase.

PLAYS WHILE YOU'RE AWAY
Your colony keeps growing and breeding while the app is closed (up to 8 hours), with a report when you come back. Start a New Colony from your best founders to go further each time.

FAIR TO PLAY
Free to play. Rewarded ads play only when you choose them. No paid random draws — even the Mutation Catalyst gives a fixed result. Optional purchases: Ad-Free, Lab Pass, catalysts and Rare Food.

No account needed — your game is saved on your device and in your iCloud.
Color-Vision Assist mode included.
