-**Berkeley War** is a variant of Egyptian War with extra rules, mostly based on arithmetic. The full list of rules is available on a [[https://zenith-rhythm-571.notion.site/Berkeley-War-f55f2234e6574ac3927e688ef0eb09fc?pvs=74|live Notion page]].

The game was invented by the [[CS184 Final Project (Spring 2023)]] group while procrastinating in the [[UPE Office]].

-The **Mul 2 = 24** rule means that the product of the last 2 cards is 24.
+The **Mul 2 = 24** rule means that the product of the ranks of the last 2 cards is 24.
+==== Basic ops & mod & exp 3 has valid Eq ====
+The **basic ops & mod & exp 3 has valid Eq** rule means that the ranks of the last 3 cards can be manipulated to form an equation of the form $$X (op) Y = Z$$, where $$(op)$$ can be any of the four basic arithmetic operations, the modulo (remainder) operator, or exponentiation.
+==== Basic ops & mod & exp 3 = 24 ====
+The **basic ops & mod & exp 3 = 24** rule is similar to the **basic ops & mod & exp 3 has valid Eq** but satisfies an equation of the form $$X (op) Y (op) Z = 24$$.
+==== Flush 3 ====
+The **flush 3** rule means that the suits of the last 3 cards are the same. The name is derived from a hand of the same name in poker.
+==== Floopa 3 ====
+The **floopa 3** rule means that the ranks of the last 3 cards can form an arithmetic sequence.
+==== Sum 3 = today's DATE ====
+The **sum 3 = today's DATE** rule (June 2023) means that the sum of the ranks of the last 3 cards is the date of the day this game is played. For example, on October 31st, this rule makes a pile where the ranks of the last 3 cards are 9, 10, Q slappable.
+==== Can’t slap the same rule as the last slap ====
+This (March 30, 2024) is the first rule which removes valid slaps from the game. The rule requires the slapping player to always vocalize the rule under which the slap applies. Two consecutive slaps are disallowed to be under the same rule.
+=== History ===
+The rule was motivated by the frequent valid slaps that the previous rules afford and the minimal number of activities available on the [[Zephyr]].
+==== Gloopa 3 ====
+The **gloopa 3** rule (July 13, 2025) is similar to the **floopa 3** rule. If the ranks of the last 3 cards form a geometric sequence, the pile may be slapped. This rule deprecates the **A39 in any order** rule, as any pile slappable by the old rule is covered by **gloopa 3**. This rule was added because the motivation behind the **A39 in any order** rule is suspect; the cards A, 2, and 4 is a geometric sequence which does not appear to be covered by any other rule.
+===== Deprecated Rules =====
+These rules are no longer part of the game (and thus cannot be used as justification for slapping for the purposes of the **can’t slap the same rule as the last slap** rule).
+==== A39 in any order ====
+The **A39 in any order** rule (December 14, 2023) applied when the last 3 cards are A, 3, or 9 in any order. This was the only geometric sequence which was thought to not have been covered by any of the previous rules. Although all of the rules so far did not have a fixed ordering of the cards, this rule was clarified to apply "in any order" due to the name "A39" implying otherwise. However, this rule is no longer part of the game; it has been replaced by **gloopa 3**.
