This is a game for one, two, three or four players. The objective is to reach the ‘Finish’ at the bottom right of the game board. Each of the yellow bridges can only be crossed if the statement on the briudge is true for the current values of b, g and r determined by the dice scores.
Players take it in turns to roll the dice then decide whether to cross a bridge or stay where they are. If they click on a bridge on which the statement is not true they are shown a panel explaining their error and they then miss that turn (or sent back to Start in the one-player version).
Click the options button to change the number of players and to enter the names of those players. This will also restert the game.
A Transum virtual trophy is available for completing the game.
An interesting extension activity would be to calculate the probability of crossing bridges or finding the best(?) route from Start to Finish.
