Editing Two-up (section)

=== Variations ===

Some variations include:
* Throwing three coins, instead of two: As at least two coins will always match, this results in a decision on every throw (two heads or two tails, with the third coin being redundant - "sudden death"), and thus a faster game, with more action, as the bets are resolved on every throw - there is no pause in gambling when odds are thrown.
* The spinner only wins after a successive run of heads: I.e., if three heads are required before a tails, with any number of odds, then "odds, heads, odds, odds, heads, odds, heads" would be a win. Casinos pay this at 7.5 to 1. This speeds up play as the Spinner can't "Toss the Kip" after a single throw (selecting a new spinner takes time, interrupting play).
* If the spinner throws successive odds they lose: I.e., if five odds thrown before a tails loses while three heads are required to win, then "odds, heads, odds, odds, heads, odds, odds" would be a loss. Casinos use this rule to provide them with the edge they need to run the game, as the Casino collects all Head/Tail bets if five odds in a row are thrown.
* In Casino games the Spinner may bet on either heads or tails. 
* In Casinos, no side bets are permitted; all bets are placed with the Casino as bank.
* Two Up game has been used to develop a [[quantum game theory|quantum game]] called Quantum Two Up <ref>{{Cite web | url=https://play.google.com/store/apps/details?id=com.QuantumGamesLLC.QuantumTwoUp | title=Quantum Two Up | website=play.google.com | archive-url=https://web.archive.org/web/20230604214648/https://play.google.com/store/apps/details?id=com.QuantumGamesLLC.QuantumTwoUp | archive-date=2023-06-04}}</ref> in which the coins are [[quantum entanglement|entangled]]. To win the game, one has to discover the law of entanglement that favors a particular coin combination.
