== Summary ==
'''Yavalath''' is an acclaimed abstract strategy game invented in 2007 by computer scientist '''Cameron Browne''' using his evolutionary game-generation program '''LUDI''', and published by '''nestorgames'''. It holds historical distinction as the first commercially published board game designed by artificial intelligence.

The game is renowned for its deceptively simple yet diabolical twist on connection games: '''Connect 4 to WIN, but connect 3 and you LOSE!'''

== Overview & Objective ==
* '''Players''': 2 or 3 players
* '''Board''': Hexagonal grid of varying sizes (Standard: 5 cells per side, 61 total cells)
* '''Pieces''': Stones in White, Black (and Red for 3-player games)
* '''Objective''': Be the first to create an unbroken straight line of '''4 of your stones''' while avoiding ever forming a line of '''3 of your stones'''.

== Core Gameplay ==
Players start with an empty board and take turns placing one stone of their color onto any unoccupied hexagonal cell.

=== Winning and Losing ===
After placing a stone, all lines extending in the three hexagonal axes passing through that stone are evaluated:
# '''WIN (4-in-a-row)''': If you create a straight line of '''4 or more''' stones of your color, you immediately '''WIN''' the game.
# '''LOSE (3-in-a-row)''': If you create a straight line of '''exactly 3''' stones of your color (without simultaneously completing 4), you immediately '''LOSE''' the game!
# '''Simultaneous Win/Loss Rule''': If a single stone placement simultaneously forms both a line of 4 and a line of 3, the '''WIN takes precedence''' and you win the game.
# '''Draw''': If all cells on the board are filled without any winning or losing line being completed, the game ends in a tie.

== Three-Player Rules ==
When 3 players play Yavalath, the game uses elimination rules:
* If a player creates a line of 3 stones, that player is '''immediately eliminated'''.
* '''Stones remain on the board''': The eliminated player's stones stay on the board for the rest of the game as neutral obstacles/blockers.
* The remaining players continue playing in clockwise order.
* The game ends when:
** A player connects 4-in-a-row (that player wins 1st place), OR
** A second player is eliminated (the sole survivor wins 1st place).

=== 3-Player Victory Points & Ranking ===
BGA ranks all three positions individually for fair ELO rating calculation:
* '''1st Place (Winner)''': '''2 VP''' (Won against both 2nd and 3rd place)
* '''2nd Place (Runner-Up / Later Survivor)''': '''1 VP''' (Won against 3rd place, lost to 1st place)
* '''3rd Place (First Player Eliminated)''': '''0 VP''' (Lost against both players)

== Game Options & Variants ==
When creating a table on Board Game Arena, several official rulesets and options are available:

=== 1. Board Size & Ruleset ===
* '''Standard (Side 5 / 61 cells)''' ''(Default)'':
** Classic game board. Connect 4 to WIN, 3 to LOSE.
* '''Five-not-four (Side 6 / 91 cells)''':
** The official large-board variant designed by Cameron Browne.
** On this spacious board, the goals scale up: '''Connect 5 to WIN''', and '''Connect 4 to LOSE'''!
* '''Compact (Side 4 / 37 cells)''':
** A high-speed, tactical blitz board with tighter margins and intense sudden-death tension. Connect 4 to WIN, 3 to LOSE.

=== 2. The Pie Rule (Swap Rule) ===
* '''Disabled''' ''(Default)'': Standard opening.
* '''Enabled''': In 2-player games, Player 1 has a natural first-move initiative. To ensure tournament fairness, Player 2 on Turn 2 is given an opening choice:
** Make a normal move with Black, '''OR'''
** Click '''"Swap Colors (Pie Rule)"''': Steal Player 1's opening stone and take over as White! Player 1 then receives Black and plays the next move.

== Strategy & Tactical Tips ==
* '''Forcing Traps''': The core tactic of Yavalath is forcing your opponent into a position where every legal move completes 3-in-a-row.
* '''Mind the Gap''': Placing stones with 1-cell gaps (e.g. stone - empty - stone) creates powerful future connection threats without triggering the 3-in-a-row penalty prematurely.
* '''The Double Threat''': If you can create a move that threatens to make 4-in-a-row in two different directions, your opponent can only block one, securing your victory on the following turn.
* '''Triangle Awareness''': Be careful when building compact clusters of stones; tight clusters often accidentally form lines of 3 along unexpected diagonal axes.
