Place all tiles inside the pouch. Have each player draw 7 random tiles and hide them from the others. Half of the players use the white side of the tiles to play, and the other half uses the black side.
Keep all remaining tiles in the pouch to draw from.
The players sit around a table or another flat surface. They must be situated so that there is always a person playing with black tiles after every person playing with white tiles, and vice versa.
One of the players who have claimed white tiles goes first. They place one tile face-up in the middle of the table. Going clockwise, the next player connects a tile to it. Then the third player connects a tile to the second player's tile, and so on.
The second tile determines the direction in which the snake is will go, i.e. you cannot place new tiles to one of the free sides of the first tile.
When adding tiles, players have to consider the sequence 0-1-2-3-4-0, in which each number refers to the number of strokes on the tiles. Additionally, the tile has to match as well - that is, strokes must connect to strokes and blank sides to blank sides.
For example: If the “snake” ends in a 2-stroke white tile, the next player can only place either a 1- or a 3-stroke black tile next to it.
If a player doesn’t have a suitable tile to play, they must draw one from the pouch and skip their turn.
When all six 0-stroke tiles are played out, all the players MUST start playing with the opposite color of their own tiles. Those who played with the white side need to flip their tiles and start playing with the black side, and vice versa.
The first player with no more tiles to place wins the game.
When all six 0-stroke tiles are played out, the players can substitute them with more 1-stroke tiles.
