Bonkers! (game)

Bonkers! (also known as This Game is Bonkers!) is a race-style board game designed by Paul J. Gruen and produced first by Parker Brothers, later by Milton Bradley, and briefly reissued by Winning Moves. The object is to be the first player to score 12 points by adding instruction cards to the empty spaces in an attempt to move to several scoring stations. The game's slogan (for all versions) is "It's Never the Same Game Twice!"
Set up.
Each game of "Bonkers!" comes with the following:
The board consists of a 55-space looping track. Most of these spaces have an outline of a track card next to it, the cards being played throughout the game; there are also three "Score" stations (one of which doubles as the starting point), a "Lose" space, two track spaces marked "Go to Lose", and one space marked "Back 15".
As the original "Bonkers!" was produced in the late 1970s, the board and game pieces accordingly had a disco styled text and motif. When Milton Bradley revived the game in the early 1990s, the board was made to appear as if the entire track and logo were made out of modeling clay; a few humorous caricatures of human faces (also made from clay) were placed in the logo and on the board as well. The game was also given a fluorescent color scheme, updated fonts, and different styled dice and pawns from the original. The 2016 Winning Moves reissue returned to the original disco motif.
Gameplay (Original 1978 Parker Brothers version).
The game starts with each player being dealt four track cards and a large "Go to Lose" card, and placing their pawns on the scoring space marked "Start". On a turn, a player rolls the dice, and moves the corresponding number of spaces shown. If the space is empty, the player places a track card in the outline next to that space and follows its directions; if already occupied by a card, the player follows the instructions on that card. A player's turn ends if landing on a space marked "Score" (scoring 1 point), the space marked "Lose" (deducting 1 point), or on an unmarked space after having already played one card. At the end of a turn, the player draws another card to replace any played during his or her turn, and the next player takes their turn.
Most of the track cards have a number between 1 and 6, in additional to 10 and 12, as well as the direction for the player to travel. The track is a loop; as pawns travel counterclockwise along the loop, "ahead" cards move the pawn forward, and "back" cards move in reverse. Other cards include "Roll Again", "Go to Nearest 'Score'", "Go to Start", and "Exchange Cards" (in which the player swaps the Exchange card for any other card currently on the track.)
If a space is occupied by another pawn, the player rolls again (except for the Lose space), while disregarding any instructions on any adjacent track card (but still scoring a point on Score spaces). 
Scoring.
The object of the game is to play track cards in a way that directs one's pawn to a "Score" space, upon which the scorekeeper moves that player's peg ahead one point. A player can also score by rolling a 12, or by means of "Entrapment": If the player's pawn ends in a continual loop (for example, ahead 2/ahead 3/back 5), that player is said to be "trapped", at which point his or her pawn is left on the space at the "front" of the trap, and the player scores one point. If a player lands on a Score space that is already occupied, he/she scores a point and rolls again.
The Lose Space.
There is one space on the board marked "Lose". If a player lands on this space, he or she loses one point, and his or her turn ends immediately (even if the space is already occupied by one or more pawns.) There are two spaces on the back side of the track that also send the player directly to "Lose". In addition, each player has a large "Go to Lose" card; at any point in a player's turn, an opponent can use this card against that player to force him or her to go to the Lose space immediately. Once a large "Go to Lose" card is played, it is removed from the game. At no time can a player's score drop below zero.
Winning.
The first player to score 12 points wins the game.
Rule changes (Milton Bradley version).
When Milton Bradley began producing "Bonkers!", there were several minor rules changes:
Other than these small changes, and the cosmetic update to the game, "Bonkers!" remained virtually unchanged from the first version.
Rule changes (Winning Moves version).
In addition to reusing the original disco theme, the 2016 Winning Moves reissue also reverted to the original Parker Brothers rules.
