How a turn works
-
1
Roll the dice
You roll four binary tetrahedra — the sum (0–4) is how far you move. The most common result is 2. A roll of 0 passes your turn.
-
2
Move a piece
Legal pieces glow. Bring a piece on from your home pile, advance one on the board, or — if you're in the shared middle row — land on your opponent's piece to send it home.
-
3
Land on a rosette
The three ✸ rosette squares are safe from capture and grant you an immediate extra roll.
