TAIJI is a Chinese term that means ‘Great Duality’ and represents the fight of Good vs. Evil, Light vs. Darkness, YIN vs. YANG.
But YIN and YANG are indivisible! That’s why both players use the same indivisible “dual” pieces called TAIJITUS.
The object of the game is to get the highest score summing up the two largest shapes of connected squares of your colour (DARK or LIGHT) by placing TAIJITUS anywhere you want in the board, as long as there’s a free space to do so. Be careful! Every time you put a TAIJITU you’re playing both colours! So you might be helping your opponent!
