Stick Duel Battle is a stickman fighting game in which a player fights against the game's AI or another real-world player in melee-style battles using a wide range of weapons while their stickman avatar floats around on a hovercraft skateboard. Although the environments that change with each fight seem to come straight out of dreams and nightmares, the game provides the player with plenty of realistic physics and weaponry. Additionally, the terrain offers fighting options that can teach a player real-world strategies and tactics.
The player selects 1P or 2P mode. If they choose 1P, they play as the orange stickman. If they pick 2P, they decide their stickman's color. After they're finished with the selection, their avatar floats on the hoverboard while waiting for weapons to drop from the sky. They must then direct the character to grab a weapon and immediately shoot at the avatar of the CPU or other player.
Stick Duel Battle offers many opportunities for a player or players to learn the best fighting strategies. They can direct their avatar to use the central platform and their hoverboard as shields. They can make it to grab a gun, bazooka or other weapon from the air or force it toward the ground to wait in a more protected position.
The player or players each receive five chances to revive and beat their enemy before they lose and the game resets.
