Coins, Arcades, Physics
Coin pushers (also known as a "Medal Games") are a fanciful mix of pachinko, slots, and those black hole simulating donation bins at the science museum. Like the Burgess Shale that lines British Columbia, the un-tumbled shelf of coins is just teeming with possibility. By adding more to the pile, your one coin may just be the one to push the others over the edge. Watching the coins ebb and flow as they're pushed, like a literal ocean of money. It's almost hypnotic. Of course there is always the thought of bumping or shaking the machine, causing the coins to fall for a huge payoff, but doing so violates the sacred vow all coin pusher players abide by.
