To play Rainy falls, you click on a coin. This causes that coin, and every other coin of that color that it is in a group with, to be removed. When this happens, the coins fall down to fill in the space, and new ones appear at the top.
To claim a ring of coins, you must click on the coins that makeup the ring, that are touching the inside. To claim multiple rings at once, you must click on a coin that makes up the wall that is touching both insides. If a ring is claimed, it removes all coins that makeup the ring, and all coins inside the ring as well.
