Pentatile

Pentatile is a geometric sandbox about growth and discovery. You place tiles along the edges of a mosaic, watching a simple seed develop into forms such as a curling creature, a crystalline tower or an unplanned pattern.

Shape the mosaic

Tiles can enclose spaces. Fill those spaces with shapes you have available, or discover new shapes that can change how the mosaic grows. The flood tool places connected copies one by one. Small discoveries can become unique Black Diamonds: collectible pieces that you cannot duplicate.

Collect discoveries

Keep discoveries in your personal library, or browse the shared compendium to find approved names and the explorers who discovered them. You can bring eligible shapes from the compendium into your active collection. You can also submit a named discovery for moderation to help expand the public compendium, with submissions limited to one per explorer every 24 hours.

Save and share boards

Save and import boards as files, or sign in to keep builds in your cloud library and share a link that opens a creation on Pentatile's website. Connecting your Steam identity to an existing web account gives you access to the same personal collection.

An evolving alpha

This alpha focuses on building, collecting and finding unexpected geometry. Its rules and tools are still evolving.
