Antheim: Ant Colony Sim

Ground water, falling rocks, a brewery, a laboratory and sentry posts. Four worlds to dig through — and the colony grows while you are away.

Dig. Feed. Defend. Grow.

Antheim is a cosy side-view ant colony simulator. You draw the tunnels with your finger, and the whole colony gets to work: ants gnaw through the soil, carry it up to the surface grain by grain and open up whatever was hidden down there.

DIG WITH YOUR FINGER Tap Dig, drag a line from any tunnel and confirm it. The longer your line, the more workers you need — the gauge at the top shows how much you can plan right now. Ants dig on their own, choose their own routes and get out of each other's way.

BUILD A REAL NEST A nursery for new ants, storage for supplies, an aphid farm for honeydew, a mushroom garden for food, barracks for soldiers. A brewery turns honeydew into mead: a keg brews, and you drink it when the moment comes — the whole colony works twice as fast. A laboratory researches lasting bonuses, and a sentry post keeps soldiers by a way out so raiders are met at the door. Tap any chamber to see exactly what it produces, or open the buildings list and jump straight to it.

THE UNDERGROUND IS NOT EMPTY Tunnels break into caves full of leaves, seeds and crystals — or into spiders, centipedes and mole crickets. When enemies attack, every ant drops what it is doing and defends the queen.

GROUND WATER Some pockets in the soil are full of water. Break into one and it pours down the shafts and floods everything below: a flooded tunnel cannot be crossed, and ants caught in it drown. Dig a tunnel underneath and the water drains away.

ROCKS THAT FALL Dig the soil out from under a rock and it drops, plugging the tunnel it lands in and crushing whoever stands there — enemies included.

A HUGE MAP The underground stretches far to the sides and deep down, until it ends in solid bedrock. Dig new ways out to the surface so the soil does not have to be carried all the way to the first entrance — but remember that raiders can use them too.

FOUR WORLDS Pine Forest, Autumn Grove, Flower Meadow and Tropical Jungle. Each has its own colony, its own soil, its own enemies and richer loot than the last. Raise a colony to level 5 to open the next one.

UPGRADE THE COLONY Strength, speed, stamina and carrying capacity — every upgrade makes the whole colony faster.

EVERY DAY Three daily goals pay crystals, with a bonus for all three and a streak for coming back. Your colony is saved to iCloud and follows you to a new device.

Free to play, with optional purchases and optional rewarded videos. No registration, no sign-in: your colony lives on your device and keeps working while the app is closed.
