Gameplay

Slap: “Slap or be slapped, become the world's best slapper” is the brand of Slap Kings. In this game, you will have to knock out your opponent by slapping him as hard as you can. Each character has a health bar and a force bar that determines how hard you can punch your rival. During a game, each character has three shots, when your turn comes, a “slap-o-meter” appears, and you have to tap on it at the right time to slap your opponent hardly. Once a character's health bar reaches 0, he’s knocked out.
Progress: Each victory will make you earn coins. Note that to progress in the game, you will have to watch ads or spend coins to increase your health and force bars.
Simple mechanics: You only need to use one button to unleash all the force you have. It is simple but really rewarding.
Unleash your true inner power: You can power up with limited-time boosts or use defense helmets to protect you. Use them wisely as the boss can be challenging to defeat.
Lots of fun characters: Slap Kings contains many amusing characters who await to try to take you down.
