Your deck is a colony

Build a deck around a queen, then start a colony from it. Every card hatches as an ant that walks the map on its own: through tunnels, across the surface and up into the trees.

Real species, real behaviours

Aphid farmers, slave-makers, social parasites, army ants, repletes, ants that play dead and majors that plug the nest with their heads.

A living map

Three layers to explore. Aphids, ladybugs, tiger beetles, grass spiders, dragonflies and rival colonies with minds of their own.

Raise, raid and fly

Lay eggs, feed larvae, launch nuptial flights, found second nests and wipe out your rivals. Or farm peacefully. Your call.

Learn as you go

A campaign teaches one thing at a time, then quick, custom and team matches let you play your way.

Collect and trade

Open packs, merge duplicates into rarer ones, trade with friends, and chase daily and weekly quests.

No ads, ever

Free to play. Anything a paying player could ever have, a free player can earn by playing.

6 inches down · the cards

Every card is a species

Each card is a real ant with its own stats and abilities, drawn by hand. More species arrive with every series.

Temnothorax ambiguus

Lives in acorns and twigs, spreads over several nests and climbs trees twice as fast.

Colobopsis impressa

Its majors have flat, plug-shaped heads that seal the nest entrance against raiders.

Nylanderia bourbonica

A fast, many-nested crazy ant whose queen speeds up the whole colony.

Lasius niger

The black garden ant: herds aphids and lives on their sugar.

Lasius claviger

A social parasite: its queen kills a host queen and takes over her workers.

Brachymyrmex depilis

Tiny and quick to grow: its colonies start with an extra-large first brood.
