| In [[gambling]], '''snake eyes''' is the outcome of rolling the [[dice]] in a game and getting only one [[Pips#Dice|pip]] on each die. The pair of pips resembles a pair of eyes, which is appended to the term 'snake' because of the long-standing association of this word with treachery and betrayal. The dictionary of [[etymology]] traces that use of the term back to 1929,<ref name="ref1">[http://www.etymonline.com/index.php?l=s&p=28 Online Etymology Dictionary]</ref> although it may be traced all the way back to the [[Ancient Rome|ancient Roman]] dice games, where 'Dogs' represented two ones. They referred to this as "the dog throw". In modern parlance, it refers to such a roll in any game involving dice. Snake eyes also refers to looking one way and passing the ball the other way in the game of Taps.

| ==Games==
| |
| Because this is the lowest possible roll, and will often be a loser in many dice games, such as [[Craps]], the term has been employed in a more general usage as a reference to [[bad luck]].
| |
| In many [[board games]] such as [[Monopoly (game)|Monopoly]], [[house rules]] may decide that rolling Snake Eyes (or any Doubles) leads to a bonus since they are rarely rolled.<ref>{{cite web|url=https://platform.rgsgames.com/Common/HTML/gameshelp/game_help_0044_0.html#howtoplay |title=How to Play Monopoly On a Roll |accessdate=2009-10-15 |publisher=rgsgames.com }}</ref>

| ==Probability==
| |
| Rolling two 6-sided dice gives you a 1 in 36 chance of getting a snake eyes each time you roll the dice.
