Coin Master is a village-building game centered around a slot machine mechanic. Players spin to earn coins, attacks, and raids, which are used to construct and upgrade their own Viking-themed village. Spins replenish over time or can be acquired through various in-game activities.

Progress is achieved by attacking other players' villages to steal coins or raiding them for larger loot. Players must also defend their own village from incoming attacks by other players. The game incorporates social elements, allowing friends to send each other spins and assist in attacks.
