Oh My Ring !

About Oh My Ring!, from BoardGameGeek:

In Oh My Ring!, you need to be quick and agile to slide your rings from one finger to the next while trying to match the combinations on the cards. Each player starts with eight colored rings: two of each color, with four on each hand. Each turn, a card is revealed that shows one or two hands and a combination of colored rings. As quickly as you can, move the rings from finger to finger to recreate that pattern before anyone else. The fastest player to do so wins the card, and whoever first collects five cards wins. Some constraints will make the task harder, such as treating one color as another or forcing you to switch rings without looking at your fingers.
