It plays like Go, but every stone obeys gravity, and a single capture can topple the board into a cascade of more captures.

How to play
The classic territory-and-capture game with one big change: you don't place a stone on any intersection, you choose a column and it drops to the lowest empty cell. Surround an enemy group so it has no liberties and it's removed, then watch the stones above fall and re-settle.
Pick a column; your stone falls to the bottom of it.
Capture by leaving an enemy group with no empty neighbours.
After captures the board collapses downward and may trigger further captures, chain reactions are the heart of the game.
You can't repeat a prior position or play pure self-capture. Most stones captured wins; the game ends when the board fills or both players pass.

Controls
Desktop: move the mouse over a column to preview where your stone lands, then click to drop it. Use the Pass button when you can't gain, and New Game to restart.
Phone & tablet: tap a column to drop a stone and tap the on-screen Pass / New Game buttons; a mouse adds the landing preview but isn't required.
Tips & strategy
Think about what falls AFTER a capture, collapsing stones can hand you (or your opponent) a second capture for free.
A column that looks safe can become deadly once gravity shifts the stones above it.
Pass only when no drop improves your count; passing twice ends the game immediately.
Set the board up so one capture cascades several times rather than chasing single stones.
Origins
Go is the oldest board game still played in its original form, and its rules are almost nothing: place a stone, surround a group so it has no liberties, and it is removed.
The original change is that you cannot place. You choose a column and the stone falls to the lowest empty cell — and when a group is captured, the stones above it fall and re-settle.
Go's depth comes from placement being completely free; the board is a blank space in which any shape can be built. Taking that away makes shape something you approach rather than draw, and makes a capture a structural event rather than a local one, because everything above it moves.
