Ludo Multiplayer Pro

Overview
Two, three, or four may play. At the beginning of the game a player's tokens are out of play and staged in one of the large corner areas of the board in the player's colour (called the player's yard ). When able to, the players will enter their tokens one per time on their respective starting squares, and proceed to race them clockwise around the board along the game track (the path of squares not part of any player's home column). When reaching the square below the home column, a player continues by racing tokens up the column to the finish square. The rolls of a single cube die control the swiftness of the tokens, and entry to the finish square requires a precise roll from the player. The first player to successfully reach the finish with all their tokens wins the game. The other players often continue the game to determine second-, third-, and fourth-place finishers.

Die rolls
Each player rolls the die, the highest roller begins the game. The players alternate turns in a clockwise direction.
To enter a token into active play from his staging area to his starting square, a player must roll a 6. If the player has no tokens yet in play and does not roll a 6, the move turn passes to the next player. Once a player has one or more tokens in play, he selects a token and moves it forward along the track the number of squares indicated by the die roll. If a player rolls a 6 he may choose to advance a token already in play, or alternatively, he may enter another of his tokens into active play. The rolling of a 6 earns the player an additional ("bonus") roll in that move turn. If the additional roll results in a 6 again, the player earns an additional bonus roll. If the third roll is also a 6, the player may not move a token and the move turn immediately passes to the next player. Players must always move a token according to the die value rolled, and if no move is possible, pass their turn to the next player.
A player may not end his move on a square he already occupies. If the advance of a token finishes on a square occupied by an opponent's token, the opponent token is returned to its owner's yard. The returned token may only be reentered into play when the owner again rolls a 6. (Unlike Pachisi, there are no "safe" squares on the game track which protect a player's tokens from being returned. A player's home column squares are always safe, however, since no opponent may enter them. Ludo played in the Indian subcontinent features a safe square in each quadrant, normally the fourth square from the top in the rightmost column. These squares are usually marked with a star.)
Variations

To get a game started faster, some house rules allow a player with no pieces on the board to bring their first piece into play on any roll, on a 1 or a 6, or allow multiple tries to roll a 6 (with three rolls being the most popular).
If a piece lands on the same space as the another piece of the same colour, the moved piece must take the preceding space.
If a player's piece lands on another of their own pieces, they are doubled and form a "block" which cannot be passed by any opponent's pieces. Or in some variations may only be passed by rolling a 6 or 1.
Doubled pieces may move half the number if an even number is thrown e.g. move 2 spaces if a 4 is thrown.
A doubled piece may capture another doubled piece (like in Coppit).
A board may have only four spaces in each "home column". All four of a player's pieces must finish in these spaces for the player to have finished the game. (See Mensch ärgere dich nicht.)
To speed the game up, extra turns or bonus moves can be awarded capturing a piece or getting a piece home; these may grant passage past a block.
