Holoplanet Architect

Holoplanet Architect is a strategy puzzle game about designing a planet. Players place Tetris-like pieces onto the 3D grid of a planet hologram, with each piece containing up to nine biomes. The score for each placement depends on its position on the planet, which biomes it neighbours, and other factors. Placing pieces over existing biomes incurs penalties, and a run can end if the score falls below zero.

Filling a side of the hologram raises the player’s level, which can unlock new pieces. These add complexity and allow higher scores, but also raise the risk of disaster. In some situations players can collect coins and spend them on upgrades, such as enlarging the hologram, skipping unwanted pieces or disabling them entirely. A score multiplier can be raised by chaining good placements into a combo streak or by buying specific upgrades. The multiplier also applies to penalties.

Making too many mistakes by overwriting biomes can trigger events such as a volcano eruption or a flood, which the player must deal with quickly to avoid further problems. Players can also unlock hand-crafted background scenes, including a futuristic city, an interstellar vessel and a drilling rig on the ocean planet Kepler-62e.
