Goal

Omega is a combinatorial abstract strategy game for 2–4 players designed by Néstor Romeral Andrés. Place stones onto a hexagonal grid to cultivate separate connected groups of your color. Your final score is calculated by multiplying the sizes of all your separate connected groups together—the highest product wins!

Components

Component	Icon	Description
White Stones		Player 1 stones (matte ivory with dark contour).
Black Stones		Player 2 stones (matte obsidian black).
Red Stones		Player 3 stones (matte ruby red; used in 3–4 player games).
Blue Stones		Player 4 stones (matte sapphire blue; used in 4 player games).
Hexagonal Board	—	Hexagonal grid of hexagonal cells available in multiple sizes (Standard: Side 5 / 61 cells).

Setup

• Players are assigned colors in fixed order: White → Black → Red → Blue.
• The board starts completely empty.
• Pie Rule (2-player option): Player 1 places 1 White and 1 Black stone. Player 2 then chooses whether to continue normally or swap colors to take over White's position.

Your turn

On your turn, you must place exactly one stone of each active color in play onto unoccupied hexagonal cells:

• 2 Players: Place 1 White and 1 Black stone.
• 3 Players: Place 1 White , 1 Black , and 1 Red stone.
• 4 Players: Place 1 White , 1 Black , 1 Red , and 1 Blue stone.

You place your own color first, followed by each opponent's color in turn order. Because you place stones of all colors, you can place opponents' stones to disrupt their structures or force unwanted merges!

End of the game and scoring

• Game End Trigger: The game ends immediately when, just before White's turn, not enough empty cells remain to complete another full round (at least $N \times N$ cells are required for $N$ players: 4 cells for 2P, 9 for 3P, 16 for 4P). A few empty cells will remain at game end.
• Multiplication Scoring: Every distinct connected group (stones sharing an edge) is counted. Your score is the product of all your group sizes multiplied together:

$$\text{Score} = \text{Group}_1 \times \text{Group}_2 \times \dots \times \text{Group}_k$$

• Example: Groups of sizes 3, 4, and 5 score $3 \times 4 \times 5 = \mathbf{60}$. A single giant group of 12 stones scores only $\mathbf{12}$.
• Winner: The player with the highest final product wins!
• Tiebreaker: If tied, the player who played latest in round order wins (Blue > Red > Black > White), compensating for earlier turn advantage.
