Niagara

You are caught with your canoe by the raging torrent of Niagara Niagara Falls. But you're not alone. Several teams compete, who will remain the longest on the rapid?

Each player chooses two canoes of the same color and place them on the starting line.
Each turn the player throws three dice: two normal D6s to determine canoe movement, and a special dice with blank sides and stars.
The star indicates that the movement mechanism is activated, thus carrying the canoes over the edge of the waterfall.
The player can move his own canoes or the canoes of his opponents!
Tree trunks floating on the river can force re-throws for the canoes passing them.
The goal is to stay the longest on the rapid.
