Stumble Boys is a multiplayer battle-arena game in which the player, via their stickman avatar, competes with other players around the world in a series of logic-puzzle, racing and other games. Whether the player emerges victorious from an arena or not, they receive gold crowns and coins as rewards.
The game automatically selects the type of battle. The player might need to attempt to guess where a section of the arena is going to drop away and direct their avatar to run away from it or remember where an image of a displayed fruit last appeared on a platform and direct the avatar to run toward it. They might also need to run through and survive deadly obstacles to reach the end of a massive race course or attempt to grab a tail on another character and wear it until time runs out.
Stumble Guys allows the player to double their rewards, receive free coins, or even try out new skins if they watch advertisements. Otherwise, they can only collect standard rewards, receive random free coins, or use their crown and coin winnings to upgrade to other character personas. They might switch their avatar to a firefighter, a thief, a boxer, a kid, a surgeon, a police officer, a woman in a summer outfit, a man in black, or a wide range of other characters. They can also win coins and characters via a daily sign-in bonus.
