Nomic is a game about changing its own rules. Here is the original rule set: http://legacy.earlham.edu/~peters/writing/nomic.htm#initial%20set
Here is a modified version, to play with using the present electronic method:
>Initial Set of Rules
>
>Immutable Rules
>
>101. All players must always abide by all the rules then in >effect, in the form in which they are then in effect. The >rules in the Initial Set are in effect whenever a game begins. >The Initial Set consists of Rules 101-116 (immutable) and >201-213 (mutable).
>
>
>
>102. Initially rules in the 100's are immutable and rules in >the 200's are mutable. Rules subsequently enacted or >transmuted (that is, changed from immutable to mutable or vice >versa) may be immutable or mutable regardless of their >numbers, and rules in the Initial Set may be transmuted >regardless of their numbers.
>
>
>
>103. A rule-change is any of the following: (1) the enactment, >repeal, or amendment of a mutable rule; (2) the enactment, >repeal, or amendment of an amendment of a mutable rule; or (3) >the transmutation of an immutable rule into a mutable rule or >vice versa.
>
>(Note: This definition implies that, at least initially, all >new rules are mutable; immutable rules, as long as they are >immutable, may not be amended or repealed; mutable rules, as >long as they are mutable, may be amended or repealed; any rule >of any status may be transmuted; no rule is absolutely immune >to change.)
>
>
>
>104. All rule-changes proposed in the proper way shall be >voted on. They will be adopted if and only if they receive the >required number of votes.
>
>
>
>105. Every player is an eligible voter. Every eligible voter >must participate in every vote on rule-changes.
>
>
>
>106. All proposed rule-changes shall be written down before >they are voted on. If they are adopted, they shall guide play >in the form in which they were voted on.
>
>
>
>107. No rule-change may take effect earlier than the moment of >the completion of the vote that adopted it, even if its >wording explicitly states otherwise. No rule-change may have >retroactive application.
>
>
>
>108. Each proposed rule-change shall be given a number for >reference. The numbers shall begin with 301, and each rule-change proposed in the proper way shall receive the next >successive integer, whether or not the proposal is adopted.
>
>If a rule is repealed and reenacted, it receives the number of >the proposal to reenact it. If a rule is amended or >transmuted, it receives the number of the proposal to amend or >transmute it. If an amendment is amended or repealed, the >entire rule of which it is a part receives the number of the >proposal to amend or repeal the amendment.
>
>
>
>109. Rule-changes that transmute immutable rules into mutable >rules may be adopted if and only if the vote is unanimous >among the eligible voters. Transmutation shall not be implied, >but must be stated explicitly in a proposal to take effect.
>
>
>
>110. In a conflict between a mutable and an immutable rule, >the immutable rule takes precedence and the mutable rule shall >be entirely void. For the purposes of this rule a proposal to >transmute an immutable rule does not "conflict" with that >immutable rule.
>
>
>
>111. If a rule-change as proposed is unclear, ambiguous, >paradoxical, or destructive of play, or if it arguably >consists of two or more rule-changes compounded or is an >amendment that makes no difference, or if it is otherwise of >questionable value, then the other players may suggest >amendments or argue against the proposal before the vote. A >reasonable time must be allowed for this debate. The proponent >decides the final form in which the proposal is to be voted on >and, unless the Judge has been asked to do so, also decides >the time to end debate and vote.
>
>
>
>112. The state of affairs that constitutes winning may not be >altered from achieving n points to any other state of affairs. >The magnitude of n and the means of earning points may be >changed, and rules that establish a winner when play cannot >continue may be enacted and (while they are mutable) be >amended or repealed.
>
>
>
>113. A player always has the option to forfeit the game rather >than continue to play or incur a game penalty. No penalty >worse than losing, in the judgment of the player to incur it, >may be imposed.
>
>
>
>114. There must always be at least one mutable rule. The >adoption of rule-changes must never become completely >impermissible.
>
>
>
>115. Rule-changes that affect rules needed to allow or apply >rule-changes are as permissible as other rule-changes. Even >rule-changes that amend or repeal their own authority are >permissible. No rule-change or type of move is impermissible >solely on account of the self-reference or self-application of >a rule.
>
>
>
>116. Whatever is not prohibited or regulated by a rule is >permitted and unregulated, with the sole exception of changing >the rules, which is permitted only when a rule or set of rules >explicitly or implicitly permits it.

>201. Players may propose a rule-change at any time. At no >point may more than one proposal be in the process of being >voted upon.
>
>
>
>202. Every time a player makes a proposal, they receive 1 >point.

>
>203. A rule-change is adopted if and only if the vote is >unanimous among the eligible voters.

>
>204. If and when rule-changes can be adopted without >unanimity, the players who vote against winning proposals >shall receive 10 points each. Players who voted for such a >proposal each >receive 5 points.

>
>
>205. An adopted rule-change takes full effect at the moment of >the completion of the vote that adopted it.

>
>
>206. When a proposed rule-change is defeated, the player who >proposed it loses 10 points.

>
>
>207. Each player always has exactly one vote.

>208. The winner is the first player to achieve 200 (positive) >points.

>
>
>209. At no time may there be more than 25 mutable rules.

>210. Players conspire or consult on the making of future >rule->changes.

>211. If two or more mutable rules conflict with one another, >or if two or more immutable rules conflict with one another, >then the rule with the lowest ordinal number takes precedence.
>
>If at least one of the rules in conflict explicitly says of >itself that it defers to another rule (or type of rule) or >takes precedence over another rule (or type of rule), then >such provisions shall supersede the numerical method for >determining precedence.
>
>If two or more rules claim to take precedence over one another >or to defer to one another, then the numerical method again >governs.

>212. If players disagree about the legality of a move or the >interpretation or application of a rule, then the player who >last voted on a proposition is to be the Judge and decide the >question. Disagreement for the purposes of this rule may be >created by the insistence of any player. This process is >called invoking Judgment.
>
>The Judge's Judgment may be overruled only by a unanimous vote >of the other players. If a Judge's Judgment is overruled, then >the player preceding the Judge in the voting order becomes the >new Judge for the question, and so on.
>
>Unless a Judge is overruled, one Judge settles all questions >arising from the game until the next turn is begun, including >questions as to his or her own legitimacy and jurisdiction as >Judge.
>
>New Judges are not bound by the decisions of old Judges. New >Judges may, however, settle only those questions on which the >players currently disagree concerning which Judgment was >invoked. All decisions by Judges shall be in accordance with >all the rules then in effect; but when the rules are silent, >inconsistent, or unclear on the point at issue, then the Judge >shall consider game-custom and the spirit of the game before >applying other standards.
>
>
>
>213. If the rules are changed so that further play is >impossible, or if the legality of a move cannot be determined >with finality, or if by the Judge's best reasoning, not >overruled, a move appears equally legal and illegal, then the >first player forced into performing an paradoxical action is >declared the winner.

>This rule takes precedence over every other rule determining >the winner
