Coin Toss. Two sides of a coin.

It's a coin toss. Will it come heads or tails? What is your fate?
The ratio of heads to tails is usually 1:1, but you can change it from the settings if you dare.

Coin flipping, coin tossing, or heads or tails is the practice of throwing a coin in the air and checking which side is showing when it lands, in order to choose between two alternatives, heads or tails, sometimes used to resolve a dispute between two parties. It is a form of sortition which inherently has two possible outcomes. The party who calls the side that the coin lands on wins.
