Rest the ring of light on your coins. Every coin inside it flips.
Chain them into each other and set off cascades across the altar.
Each river ends in a guardian, a giant coin with a curse of its own. When it lands tails, hit it for double.
Come up short when the ferry lands and the river takes you. Your memories stay.
