Coin machines are interactive objects in Rustyard.
The coin dispenser is rectangular, with the coin appearing on the bottom while a rectangular lid is placed on the top part. The lid appears to have some screens on it, and on the right side of the lid is what seems to be wires.
The player can drag coins out of the machine to activate walking robots or bridge machines. The coin machine dispenses an unlimited amount of coins, although only up to six coins can be out of the dispenser. Coins can interact with blocks and other coins, but not robots. Although the coins appear shiny the dispenser appears old and rusty like all the other machines in the game.
