If you would like use the '''MathML''' rendering mode, you need a wikipedia user account that can be registered here [[https://en.wikipedia.org/wiki/Special:UserLogin/signup]]
In [[gambling]], '''snake eyes''' is the outcome of rolling the [[dice]] in a game and getting only one [[pip (counting)|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.

Registered users will be able to choose between the following three rendering modes:  
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>

This is a preview for the new MathML rendering mode (with SVG fallback), which is availble in production for registered users.

If you would like use the MathML rendering mode, you need a wikipedia user account that can be registered here [[1]]

  • Only registered users will be able to execute this rendering mode.
  • Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.

Registered users will be able to choose between the following three rendering modes:

MathML

E=mc2


Follow this link to change your Math rendering settings. You can also add a Custom CSS to force the MathML/SVG rendering or select different font families. See these examples.
