Brackenfen Hollow

Welcome to Brackenfen Hollow, a night-forest lighting puzzle about placing firefly lanterns with care.

Each grove is a grid of open glades and dark pines. Tap a glade to plant or remove a lantern. Light travels along the row and column until a pine stops it. Your goal is to make every glade glow.

How to play
- Tap a glade to plant a firefly lantern. Tap again to remove it.
- A lantern lights its own tile, then its row and column, until a pine blocks the beam.
- Every glade must be lit.
- Two lanterns must not shine on each other.
- A numbered pine needs exactly that many lanterns in the four adjacent tiles.
- There are ten groves. Later groves add more pines and tighter numbers.
- Lighting all ten groves completes a run.

Tips
- Start with numbered pines. A 0 means no lantern may sit beside it.
- If two lanterns clash, one of them is on the same open line.
- A pine can hide a lantern from another lantern on the far side.
