Prismgrove

Prismgrove is a light-bending puzzle with an idle heart. Sun Wells pour beams across small handcrafted groves. Place mirrors, splitters, lenses and prisms to route the light through crystals. Every lit crystal earns Glow, which grows your crystals, buys more pieces and wakes new groves.

Your layout is your income: light passes through crystals and keeps going, so one clever beam can feed a whole chain. Light a crystal from two, three or four sides at once and it resonates for ×2, ×4 or ×8 glow. In Prism Hollow, split white light into red, green and blue and feed every crystal its true colour.
