King of the Course is a golf game similar to Flick Golf, the developer's previous golf game. It uses the PGA license and includes several real world golf courses including TPC Sawgrass, St. Andrews and Banff Springs. The game is entirely played with touch screen controls. By touching and holding in the lower half of the screen the player starts the backswing and and to get a good shot the player has to swipe upwards when the club reaches the green backswing zone. Overswinging adds more distance to the shot but lowers the accuracy. For a good accuracy the player has to swipe in a straight line. When the ball is in the air the player can apply aftertouch to control the flight path and spin of the ball. This is done by quick and repeated swipes across the screen.
The game is built around challenges. For each challenge there are certain number of shots to reach a certain score that will earn one to three stars. To complete a challenge and unlock the next one at least one star has to be earned. Challenges include: bulls eye where the player scores points by hitting the target zones around the hole (with the zones closest to the hole being worth most points), longest putt which works like bulls eye but with putting and stroke play which is more similar to real golf and where the player has to achieve a score of par. When failing a challenge the player loses a ball and when all out of balls there is a wait for them to recharge or buy new ones.
Since the game uses a free-to-play model there are various IAPs that can be bought. This is done with tokens that can be bought for real money. It is possible to upgrade the player's golfer or to buy a new one. The golfers have stats in four categories: accuracy, spin, luck and putting. These can also be upgraded in-game with the stars earned from challenges. There are also various boosts that can be activated in challenges. For example sticky balls that causes the ball to stick to the ground when activated.
