1.1. All players must wear a
Calvinball mask (See Calvinball Equipment - 2.1).
No one questions the masks (Figure 2.1).
*IMPORTANT -- The following
rules are subject to be changed, amended, or
dismissed by any player(s) involved.
1.2. Any player
may declare a new rule at any point in the game
(Figure 1.2). The player may do this audibly or
silently depending on what zone (Refer to Rule
1.5) the player is in.
1.3. A player may use the
Calvinball (See Calvinball Equipment - 2.2)in any
way the player see fits, from causal injury to
self-reward.
1.4. Any penalty legislation may
be in the form of pain, embarassment, or any
other abasement the rulee deems fit to impose on
his opponent.
1.5. The
Calvinball Field (See Calvinball Equipment - 2.3)
should consist of areas, or zones, which are
governed by a set of rules declared spontaneously
and inconsistently by players. Zones may be
appear and disappear as often and wherever the
player decides. Zones are often named for their
effect. For example, a corollary zone would
enable a player to make a corollary (sub-rule) to
any rule that has benn, will be, or might be
declared. A pernicious poem place would require
the intruder to do what the name implies. Or an
opposite zone would enable a player to declare
reverse playibility on the others. (Remember, the
player would declare this zone oppositely
by not declaring it.) (Figure 1.5a and 1.5b)
1.6. Flags
(Calvinball Equipment 2.3) shall be named by
players whom shall also assign the power and
rules which shall govern that flag for particular
moment in that particular game(Figure 1.6).
1.7. Songs are an integral part
of Calvinball and verses must be sung
spontaneously through the game when randomly
assigned events occur. These random events will
be named and pointed out after the player causes
the event.
1.8. Score may be
kept or disregarded. In the event that score is
kept, it shall have no bearing on the game nor
shall it have any logical consistency to it.
(Legal scores include 'Q to 12', 'BW-109 to
YU-34, and 'Nosebleed to Trousers'.) (Figure 1.9)
1.9. Any rule above that is carried out during
the course of the game may never be used again in
the event that it causes the same result as a
previous game. Calvinball games may
never be played the same way twice (Figure 1.9)
