This is an untested game. It might just turn out to be random and mean. Ideally this is a social game revolving around faceoffs where you try to convince your opponent to be peaceful, and suss out the other player's intentions.

The game involves a group of players, let's say 4-10, who go through a sequence of faceoffs until one player is left. For each faceoff, two players are chosen randomly, and each player has a loonie coin. Each player taps his coin on the bottom of the table, then puts it on the table with his hand covering it. When both players announce that they are ready, the hands are lifted off.

After each faceoff a penny (or some other token, like bingo chips or jellybeans) is added to a pile on the table. In addition, every time a player survives a faceoff, the player gains a penny. If both players show heads, they both survive. If player A shows a head and player B shows a tail, player A can no longer participate in faceoffs, while player B gets the whole pile. If they both show tails, a coin toss decides which player is out and which gets the pile.

At the end of the game one of all the players' pennies is chosen at random, and that player wins.
 
 
 
 

Loonies are the Canadian dollar coins. They're not very practical because they're hard to see, but I would use them. Canadian nickels with their great beaver image might be better, more visible. The pieces from Othello / Reversi, with their black and white faces, are very visible, and have a drama to them.

A faceoff involves two randomly chosen players who each have a loonie coin. The idea is for the player to keep the coin hidden from everyone else - no "this is what I was going to show" - until the end of the faceoff. A player taps the face of the coin on the bottom of the table, then puts the coin on the table with a hand over it. The tapping ensures that the player has the option of secretly changing the top face of the coin. In addition it's a fun little iconic ritual. A player can still take the coin off the table again or look at it, but this means that the player would have to retap, and the opponent would also have to retap. When both players announce that they are ready, they take their hands off their coins.

We're going to need a verb for showing a tail. "Flipped / out" fits the theme.

Flipping a coin does not have to be the classic tossing in the air. You can stand it up on the table and flick it to spin it, then slap your hand down on it. One player calls heads or tails.

It's up to you to figure out the procedures for choosing who participates in faceoffs (dice? drawing cards?), and which penny is chosen as the winner.

So Fred just best replica watches flipped out poor trusting Jillian, and Fred gleefully raked in a pile of pennies, more than anyone else. Should you flip out Fred? What is your reasoning?
Should you break up couples?
How does it work when there are two players remaining?

How about an indivisable collectable coin as a prize?
