Can't Stop is a board game designed by Sid Sackson originally published by Parker Brothers in 1980; however, that edition has been long out of print in the United States.
If the neutral markers are on the board, but only in columns that cannot be made with any pair of the current four dice, the turn is over and the player gains nothing.
[1][2][3] The official rules merely say "If you can place a marker, you must...", not stating if that applies before or after a player decides how to subdivide the four dice.
Note that this variant makes it very difficult to pass a player with an established position on the columns on the side of the board (like 2 and 12).
In Can't Stop Express, players roll dice to score points.
[5] The reviewer Mikko Saari from Lautapeliopas considered the game to be "very simple" and praised the engagement due to the push-your-luck mechanism.
