The Rain board

The pile, the active suit, and your hand.

• Their hand (top) — how many cards your opponent holds. You can't see them.
• Draw pile (left) — tap it when you can't or don't want to play. You take one card and your turn ends. Facing a penalty, the same pile says ACCEPT +4 (or however many) — tap it to take them.
• The pile (middle) — play a card of the same suit or the same rank as the top card. When a card changes the suit, the pile shows which suit is live. A waiting penalty shows under it, like +4.
• Your hand (bottom) — drag a card onto the pile to play it. You win when your hand is empty.
• Turn (top right) — the current turn number.
• The ring round their circle (top left) — lights up while your opponent is in the match. See Is someone there?
