PlayNewtMonster Island is a free voxel kaiju-raising and colony sim released on itch.io on October 25, 2026. Choose an egg, name it and raise it from hatchling to titan in the Great Den, a floating rock over a bottomless abyss, while thirteen clans build, trade, quarrel and defend the island around you. It runs in the browser, phones included, and saves on each device.

Raise your kaiju

  • Six original kaiju: Axoltzin the lake titan, Lunokrylo the moon-moth, K'uk'ulzmey the feathered serpent, Leshkan the walking forest, Vodyachaak the rain-caller and Zharkinich the sun-firebird.
  • Warm the egg and sing to it until it hatches, then feed, play, groom and let it sleep.
  • Six growth stages, each with its own voxel body; the moth even spins a cocoon.
  • From stage three its gift helps the whole island, and once it is big enough you can send it to fight.

Keep the island

  • Thirteen clans farm, fish, hunt whales, trade by caravan and boat, make pacts, feud and sometimes break away.
  • Research walls, weapons and flight: balloons, blimps, airships and air fortresses. The Den can only be reached by air.
  • A food web of grazers, hunters, fish schools and whales that responds to how the clans use them.
  • Pirates by sea and sky and wild kaiju come for the Den and the egg.
  • Seasons and storms, hurricanes, tornadoes, blizzards, floods and tsunamis.
