Dash Party is a real-time, battle arena game that pits one or two players against multiple online players from around the world. Similar to slither games, the player's character slides around in the arena on their front. Yet, they have a human form with their arms stretched above their head and their hands holding a weapon. They must use their weapon to slash, split and kill their opponents.
The game gives the player's character different cutting weapons the longer they remain in the arena, including a sword and a chainsaw. The player starts out in the Amateur League, but they can progress to other levels with more wins.
Successful slide attacks in Dash Party generate coins that the player collects in a arena to buy extra life, speed and knife upgrades. The player also receives extra coins by watching ads to gain access to a 3x multiplier and as rewards for cutting through objects instead of characters during bonus levels. Lastly, they receive a present after so many levels that unlocks a new character.
