Mermaid Rain is a Japanese game from the makers of Train Moder.
Over five rounds, players try to collect five different types of goods by moving around the sea. The game uses two phases: first is the "surf predicting" phase where players play melds of cards in a Taj Mahal-type mechanic. The melds determine player order, selection of "wave tile", and give other benefits. In the second phase, "surf riding", players place their wave tiles on the board and then use cards to move through the sea on the waves to collect goods.
The game is playable with English rules as the components are either language-independent or easily decipherable.
