Lazo is for two players. The board is a grid, in the overall shape of a trapezoid, of 145 triangular holes. One player sits next to the long edge of the yellow board, and the opponent sits opposite. The players decide who takes the white tiles and who takes the black tiles.
There are 95 white and 95 black tiles, with a peg on the underside of each tile. When the tiles are placed on the board with the pegs in the holes, they fit together in a hexagonal (beehive) grid pattern.
Three mutually adjacent tiles on the same level either share a common vertex
or else they form a gap that is the same size and shape as the holes on the board.
The board is empty at the start of the game. Black moves first. Players alternate making one move at a time. Each move consists of placing one tile of your color on the board, peg side down, so that the peg fits in a vacant hole. You are allowed to play anywhere on the board surface. At the start of the game, this is the only place you can play. If the hole is a gap formed by three mutually adjacent tiles on the same level, you may play there as long as this space is adjacent to another tile of your color. Tiles on the same level are adjacent if they share an edge. Tiles on adjacent levels are adjacent to each other if one of them is one of the three tiles that the other tile is resting on. In other words, two tiles are adjacent if they touch each other.
Tiles A and B are on the same level and share an edge,
so they are adjacent.
Tile B is resting directly on tile C, so they are also
adjacent.
Tile C is close to tile A, but these tiles are not adjacent.
