Basic Trope: A coin that has matching sides, usually to cheat in a game.
- Straight: Alice and Bob are supposed to do a coin flip to decide on whether they should go to the movies or the museum. Alice really wants to see a movie, so she uses a coin with two heads to get her way.
- Exaggerated: Alice has a whole bunch of coins that match on both sides just so she can win in these kinds of games.
- Downplayed: Alice has a coin that's different on both sides, but still somewhat more likely to flip to the side she wants.
- Justified:
- Alice wants her way, but still wants it to look like she's won fair and square.
- The Show Within a Show's script calls for Bob's character to win the coin flip, so Alice swaps in the coin that matches his call to guarantee his 'win'.
- Alice's coin is a defect, but she wants to keep it because of said defect since it helps her cheat.
- Inverted: Alice and Bob have the choices of going to the museum or the movies, but they want more options, so instead they use a many-sided die.
- Subverted:
- Alice's coin seems to have matching sides, but there is actually a difference between the two sides...
- Alice's coin's two-headedness is only a rendering error.
- Heads, Heads, Edge.
- Double Subverted: … which is so minuscule that Alice doesn't bother.
- Parodied: Alice uses a two-headed coin, and calls tails.
- Zig-Zagged: ???
- Averted:
- Alice does not use a coin that has matching sides.
- No coin toss happens.
- Lampshaded: ???
- Invoked: Charles placed a head stamp both bottom- and top-side of the stamping machine. note
- Exploited: Bob knows Alice's coin is two-headed, so he calls out heads before she can and wins the toss.
- Defied:
- Bob notices Alice cheating, and doesn't let her use the coin.
- Alice has the coin restamped with both a head and a tail die.
- Discussed: ???
- Conversed: ???
- Implied: While the scene ends before the coin slows down enough to say for certain, as it spins around we see flashes of heads, but not of tails.
Back to Two-Headed Coin... or maybe Two-Headed Coin, which side do you wanna call?
