Darts King is a sports game that focuses on competitive darts play. The player's goal is to win games of darts against other online players. The object of the game is for them to reach a 0-point score before their opponent.
The player receives an avatar image and identification number. On the home screen, they can use the far-left avatar profile button to select a different image.
The play area features a round dart board on a wood plank wall illuminated by two light bulbs. The game tracks the player's score at the top-left corner and their opponent's score at the top-right corner.
The player can achieve specific single scores by hitting triangular areas connected to numbers along the outer edge of the board. If they hit the outer double ring below the numbers, they receive double points. If they hit the inner ring, they receive triple points. If they hit the bullseye, they receive 50 points.
Darts King helps the player by providing them with instructions and highlighting the spots on the board that can help them win. During the final part of the competition, the game continues until one player reaches the 0-point level. That said, if a player hits a spot that offers more points than they still need, they experience a bust and lose their turn.
The player receives coin winnings. They can watch an advertisement to earn more coins. They can claim task and achievement awards by using the trophy button on the home screen. They can also use the shopping cart button to purchase access to new tips, barrels, shafts and flights that can help them improve their chances of winning.
