The main bonus feature in Double Top Darts is the free spins round. The bonus game is awarded when three bonus symbols land anywhere across reels 1,3, or 5. In the bonus round players will be awarded 12 free spins and additional wilds will be added to the reels which are determined by the outcome of the first two darts thrown. Like in the main game, to win players must secure a line win in which 3-5 symbols are matched on a winning line.
