Dobble Chelsea - Rules of Play says:

Each card in Dobble features eight different symbols, with the symbols varying in size from one card to the next. Any two cards have exactly one symbol in common. For the basic Dobble game, reveal one card, then another. Whoever spots the symbol in common on both cards claims the first card, then another card is revealed for players to search, and so on. Whoever has collected the most cards when the 55-card deck runs out wins!
