The beating heart of any online slots game is the symbols that it brings to the table. The symbols in Pirate’s Plunder include the more common slot machine symbols, as well as a few pirate related ones for good measure. The main symbols are the skulls, treasure chests, swords, pistols, rum, fruits, beer, hooks, and a jewelled cross. The wild symbol in Pirate’s Plunder is the Jolly Roger. This symbol can take the place of any other symbol except for the scatter symbol. Pirate’s Plunder also comes with a great dedicated bonus feature. If you land two to five scatter symbols then you win free spins relative to how many scatter symbols showed up (2, 5, 10, and 20 for 2, 3, 4, and 5 respectively). It’s also possible to re-trigger free spins, so you can win free spins even on a free spin.
